Use n OSHA/CSA pproved non-conductive step or pltform ldder specified for t lest kg (300 lb.) lod cpcity. Fire suppression systems A fire suppression system is the responsibility of the customer. The insurnce underwriter, locl fire mrshl, or locl building inspector, or ll three, must be consulted in selecting fire suppression system tht provides the correct level of coverge nd protection. IBM designs nd mnufctures equipment to internl nd externl stndrds tht require certin environments for relible opertion. Becuse IBM does not test ny equipment for comptibility with fire suppression systems, IBM does not mke comptibility clims of ny kind nor does IBM provide recommendtions on fire suppression systems. Power cbles Use only IBM pproved UL power cbles. For your sfety, IBM provides power cble with grounded ttchment plug to use with this IBM product. To void electricl shock, lwys use the power cble nd plug with correctly grounded outlet. IBM power cbles used in the United Sttes nd Cndre listed by Underwriters Lbortories (UL) nd certified by the Cndin Stndrds Assocition (CSA). For units intended to be operted t 115 volts: Use UL-listed nd CSA-certified cble set consisting of minimum 18 AWG, Type SVT or SJT, three-conductor cble, mximum of 15 feet in length nd prllel blde, grounding-type ttchment plug rted 15 mperes, 125 volts. For units intended to be operted t 230 volts (U.S. use), use UL-listed nd CSA-certified cble set consisting of minimum 18 AWG, Type SVT or SJT, three-conductor cble, mximum of 15 feet in length nd tndem blde, grounding-type ttchment plug rted 15 mperes, 250 volts. For units intended to be operted t 230 volts (outside the U.S.), use cble set with grounding type ttchment plug. The cble set must hve the pproprite sfety pprovls for the country in which the equipment is to be instlled. IBM power cbles for specific country or region re usully vilble only in tht country or region. Connect ll power cbles to correctly wired nd grounded electricl outlet. Ensure tht the outlets supplies correct voltge nd phse rottion ccording to the system rting plte. Ensure tht ll customer fcility outlets re protected with circuit brekers rted t mximum for 30 Amps. The power cble plugs operte s the system min-disconnection method. Lekge current XIV systems incorporte electromgnetic-interference filter cpcitors tht re required to prevent electricl noise from penetrting the power grid. A chrcteristic of filter cpcitors, during norml opertion, is high mount of lekge current. Depending on the storge configurtion, this lekge current cn rech 100 ma. Sfety nd environmentl notices xi

12 For the most relible opertion, do not use Ground Fult Circuit Interrupter (GFCI), Erth Lekge Circuit Breker (ELCB), nd Residul Current Circuit Breker (RCCB) type circuit brekers with XIV systems. The XIV system is certified for sfe opertion nd is complint with IEC, EN, UL, CSA stndrds. However, if lekge detection circuit brekers re required by locl electricl prctice, the brekers must be sized for lekge-current rting of 300 ma or greter to reduce the risk of server outge cused by erroneous nd spurious tripping. Site preprtion The IBM service representtive cn only minimlly reposition the rck t the instlltion site, s needed to service the XIV system. The customer is responsible for using professionl movers or riggers in the cse of equipment reloction or disposl. Attention: Do not tilt the XIV system rck more thn 12.5 degrees. If more clernce is needed for models 281x-114, 281x-214, or 281x-314 rcks, the weight-nd-height-reduced shipping (feture code 0200) must be ordered to reduce the height of the rck. When this option is ordered, dt modules re shipped seprtely, nd the rck top cover cn be removed by the IBM service representtive before the XIV system is moved to its finl loction by professionl movers. DANGER Hevy equipment - personl injury or equipment dmge might result if mishndled. Use only professionl movers. xii IBM XIV Gen3 281x-11x, 281x-21x, nd 281x-314 Plnning Guide

25 Chpter 3. Plnning for compression Before implementing IBM Rel-time Compression on your system, ssess the current types of dtnd volumes tht re used on your system. Note: If you re using IBM XIV Storge System softwre version 11.6.x or lter, nd IBM XIV Mngement Tools version 4.6 or lter, you cn see storge sving estimtes (even if compression is not licensed or is just disbled). The decision to compress volumes cn be bsed on the expected storge svings of the compressed dtnd the expected effect on performnce. Understnding compression rtes, rtios, nd svings Consider use cse where the originl cpcity required to hold dt ws 100 TB, but 20 TB fter compression (100 TB = 20 TB + 80 TB sved). The following vlues help to clrify these terms: Compression rte = 80% Compression svings rte = 80% Compression svings = 80 TB Prerequisites nd limittions Compression rtio = originl size (100 TB) divided by the size on disk fter compression (20 TB) = 5:1 When you consider svings, it is esiest to use the compression rte. The compression rtio helps in understnding how much effective dt you cn store on your system. So, when you hve 5:1 compression rtio, you will be ble to store 500 TB of dt on 100 TB of physicl cpcity. The following prerequisites nd limittions re for XIV Storge System models 114 or 214, with XIV Storge softwre version 11.6 or lter, nd models 214 or 314 with XIV Storge softwre version or lter. Tip: Consider using version with model 214 to benefit from improvements like compressed volume size. v Compressed volumes must be creted in thin-provisioned pools. v To convert mirrored volume from uncompressed to compressed (or vice vers), the mirroring reltionship for tht volume must first be removed nd then recreted fter the conversion. v Snpshots cnnot be converted from compressed to uncompressed nd vice vers. Snpshots tht lredy existed before volume ws converted from non-compressed to compressed re not converted nd re not vilble with the converted volume. v Spce requirements: Copyright IBM Corp. 2008,

26 Prior to enbling compression, the system must hve minimum of 17 GB of free hrd spce vilble. Enbling compression reserves 17 GB from the vilble system hrd cpcity. It is reserved for internl system use only. Before the compression process, there must be enough spce for both compressed nd uncompressed versions of the volume. For models 114 nd 214 with version : Volume size must be t lest 103 GB before compression. For models 214 nd 314 with version : Volume size must be t lest 51 GB before compression. The following is prtil list of limittions. v Up to 1024 volumes nd snpshots cn be compressed. v The following limits pply to compression cpcity: System must hve minimum of 17 GB of free hrd spce to enble IBM Rel-time Compression. Thin pools require minimum of 17 GB of free hrd spce vilble to convert or trnsform volumes from uncompressed to compressed. Thin pools require minimum free soft spce tht is t lest s lrge s the volume size tht is being converted from uncompressed to compressed. When you decompress compressed volume, you must hve both free hrd spce t lest the size of the uncompressed volume nd free soft spce. It is good prctice to hve free soft spce t lest the size of the uncompressed volume. The Storge Admin cn modify the system soft cpcity. Use the XCLI commnd, system_soft_cpcity_set soft_size=sizegb. For exmple: system_soft_cpcity_set soft_size= The soft cpcity size of the system cn be set to the following: - Up to 3 times the size of the hrd cpcity of the system (with version ) - Up to 2 PB (with version ) And s low s the mximum size between the currently llocted soft cpcity nd the system's hrd cpcity (whichever is greter). The current hrd, soft, nd llocted soft cpcity cn be retrieved by using the system_cpcity_list commnd. Tip: Over-provisioning with Rel-time Compression is sfe, since compression rtios re predictble nd stble. v To compress n uncompressed volume in thick pool, it must be moved to thin-provisioned pool with compression enbled. v Only one conversion process cn be ctive t ny time. v Adding module, rebuilding disk, or upgrding the system suspends nd then resumes the conversion process. For the most current informtion bout the limittions, refer to the Limittions section of the IBM XIV Storge System Gen3 Relese Notes, versions nd IBM XIV Gen3 281x-11x, 281x-21x, nd 281x-314 Plnning Guide

27 Estimting compression svings Compressible dt cn be identified nd expected compression rtios cn be estimted even before using compression. On n XIV system supporting compression, the compression rtio for ll uncompressed volumes in the system is continuously estimted, even before enbling compression. The decision to use compression cn be bsed on the expected storge svings of the compressed dtnd the expected effect on performnce (throughput nd ltency) of the compression processing overhed. Informtion on compression usge cn lso be monitored using the XIV GUI to determine the potentil svings to your storge cpcity when uncompressed volumes re compressed. You cn view the totl percentge nd totl size of cpcity svings when compression is used on the system. Compression svings cross individul domins, pools nd volumes cn lso be monitored. These compression vlues cn be used to determine which volumes hve chieved the highest compression svings. See the IBM XIV Storge System Mngement Tools User Guide for more informtion on monitoring nd using compression. Note: Keep in mind tht the expected storge svings cn vry from 5% higher or lower thn the ctul compression rtio. A negtive estimted compression rtio cn be due to metdt tht consumes storge spce on volume, even when 0% estimted compression rtio is received from dt tht cnnot be compressed. Effective cpcity Effective cpcity is the mount of storge tht is llocted to pplictions. Using thin-provisioned storge rchitectures, the effective cpcity is virtully lrger thn the rry usble cpcity. This is mde possible by over-committing cpcity, or by compressing the served dt. Compression is the preferred method to pply thin-provisioning to usble cpcity, since the compression rtio is highly predictble. Hrd cpcity denotes usble, non-compressed cpcity, wheres soft cpcity denotes the nominl cpcity tht is ssigned to volumes, nd reported to ny hosts mpped to those volumes. Thin provisioning denotes committing more soft cpcity thn hrd cpcity. Soft cpcity is ssigned t pool level. In the cse of compression, thin-provisioning is obvious: compressed volume will forever use less hrd cpcity thn soft cpcity. In XIV terms, the effective cpcity is llocted out of the system soft cpcity, nd is the sum of the sizes of ll the llocted volumes. In n XIV System Gen3 Turbo Compression model 314, the mximl, non-compressed hrd cpcity supported in single XIV frme is 485 TB (15 modules, 6 TB drives). However, n XIV frme cn effectively ccommodte up to 2 PB of rel written dt - when the dt is compressed. With very high compression rtes, filling system up to 2 PB of soft cpcity my not require lot of usble cpcity. The mximum soft cpcity tht cn be llocted to volumes in XIV is 2 PB. Considering the compression rtio for typicl dt profiles on XIV systems, the effective soft cpcity leverged within 15-module frme will rnge from 1 PB to 2 PB.

28 dt, nd void over-sizing the system, it is importnt to ssess the expected compression rtio for the stored dt. The Comprestimtor commnd-line host-bsed utility cn be used for tht purpose. For more informtion on Comprestimtor, see Estimting compression svings using IBM Comprestimtor utility on pge 9. The mximum effective cpcity is reched when ll the soft cpcity hs been llocted to volumes (tht is, 2 PB). For more informtion on how to fine-tune soft nd hrd cpcities, refer to "Additionl spce utiliztion guidnce" in the Rel-time Compression with IBM XIV Storge System Model 314 (REDP-5306) Redbook. Generl compression sving guidelines The best cndidtes for dt compression re dt types tht re not lredy compressed. Compressed dt types re used by mny worklods nd pplictions, such s dtbses, chrcter/ascii bsed dt, emil systems, server virtuliztion, CAD/CAM, softwre development systems, nd vector dt. The following exmples represent worklods nd dt tht re lredy compressed nd re, therefore, not good cndidtes for compression: v Compressed udio, video, nd imge file formts: File types such s JPEG, PNG, MP3, medicl imging (DICOM), nd MPEG2. v Compressed user productivity file formts: Microsoft Office 2007 nd newer formts (.pptx,.docx,.xlsx, etc.), PDF files, Microsoft Windows executble files (.exe), etc. v Compressed file formts: File types such s.zip,.gzip,.rr,.cb, nd.tgz. IBM Rel-time Compression is best suited for dt tht hs n estimted compression svings of 25% or higher. There re vrious configurtion items tht ffect the performnce of compression on the system. Different dt types hve different compression rtios, nd it is importnt to determine the compressible dt currently on your system. The IBM Comprestimtor, host-bsed utility, cn be used to estimte expected compression rtes. Compressing selectively, bsed on sving estimtes, optimizes both cpcity use nd performnce. For more informtion on Comprestimtor, see Estimting compression svings using IBM Comprestimtor utility on pge 9. The following tble shows the compression rtio for common pplictions nd dt types: Tble 4. Compression rtios for different dt types Dt Types/Applictions Compression Rtios Productivity Up to 75% Dtbses Up to 80% CAD/CAM Up to 70% Virtuliztion Up to 75% Note: The required cpcity reserve is equl to the size of the volume (not the used cpcity, but the volume size). 8 IBM XIV Gen3 281x-11x, 281x-21x, nd 281x-314 Plnning Guide

29 Estimting compression svings using XIV GUI The XIV softwre provides built-in comprestimtor function from the XIV Mngement Tools GUI on n XIV system supporting Rel-time Compression. From the XIV GUI, compressible dt cn be identified nd expected compression rtios cn be estimted even before using compression. Compression does not even hve to be enbled to view compression sving estimtes. Continuous sving estimtes re visible t ll times for uncompressed volumes. And the compression rtio for ll uncompressed volumes in the system is continuously estimted in cyclicl mnner. Tht is, the potentil svings estimtions pper continuously nd re updted every few hours. The decision to use compression cn be bsed on the expected storge svings of the compressed dtnd the expected effect on performnce (throughput nd ltency) of the compression processing overhed. Figure 1 displys the compression svings (in both percentge nd GB vlues) of compressed volumes nd uncompressed volumes with estimtes of potentil svings, should the uncompressed volumes be compressed. These potentil compression svings re constntly being updted. Figure 1.

30 Comprestimtor is commnd-line host-bsed utility tht cn be used to estimte the expected compression rte for block-devices. The utility uses dvnced mthemticl nd sttisticl lgorithms to perform smpling nd nlysis efficiently. The utility lso displys its ccurcy level by showing the compression ccurcy rnge of the results tht re chieved bsed on the formuls it uses, deviting plus or minus 5 percent bsed on the formuls tht re used by the RACE implementtion. The utility runs on host tht hs ccess to the devices to be nlyzed. It runs only red opertions, so it hs no effect on the dt tht is stored on the device.

38 Dtnd interfce module fetures This informtion describes the dtnd interfce module options for the IBM XIV Storge System. For dtnd interfce modules with 1 TB limited-cpcity, the modules contin 2 TB DDMs, but the usble cpcity is limited to 1 TB by using the short-stroking method. By short stroking the DDM, only the outer sectors of the disk pltters re used to store dt. Hed repositioning delys re minimized, which results in shorter ccess times nd incresed I/O performnce. Cpcity on Demnd (CoD) modules re modules tht re physiclly instlled in the rck nd fully functionl but tht re not 'ctivted' for use until more cpcity is needed. Additionl cpcity is ctivted by ordering miscellneous equipment specifiction (MES) with the pproprite CoD ctivtion feture. In relity, instlling the CoD ctivtion feture llows for the use of n dditionl, incrementl portion of totl system cpcity tht is proportionl to the shre of CoD module in the system. For exmple in 15-module system, if three of the modules re ordered s CoD (nd not yet ctivted), this mens tht initilly the customer is only licensed to use 12/15 of the system usble cpcity. By ctivting the three CoD modules, the customer will then be licensed to fully utilize the system usble cpcity (or 15/15 of the cpcity). CoD ctivtion fetures do not require physicl instlltion. If you receive notifiction to instll this feture, only report the instlltion ccording to the field-reporting guide for your respective geogrphicl re. Tble 12.

Prepre the site in dvnce so tht professionl movers or riggers cn trnsport the equipment to the finl site within the computer room. If the site cnnot be prepred before the delivery time, you must mke rrngements to hve the professionl movers return to finish the trnsporttion lter. Only professionl movers cn trnsport the equipment. An IBM service representtive instlls the XIV system. The IBM service representtive cn only minimlly reposition the rck within the room, s needed to complete required service ctions. Professionl movers or riggers re required to trnsport the XIV system rck s close to the instlltion site s possible becuse of its weight. Professionl movers or riggers re lso required to relocte or dispose of the XIV system. Plnning for floor nd spce requirements You must ensure tht the loction of the XIV system meets spce nd floor requirements. Procedure Complete the following steps to ensure tht the plnned instlltion loction meets spce nd floor lod requirements: 1. Decide whether the XIV system is to be instlled on rised floor. 2. Determine whether the floor meets the floor-lod requirements for the XIV system. 3. Clculte the mount of spce need for the rck footprint nd service clernce requirements. 4. Determine where to plce the rck in the instlltion site, bsed on the floor-lod nd spce requirements. 5. If the loction hs rised floor, prepre the rised floor with cble cutouts nd required ventiltion. 6. If the loction is not rised floor, resolve ny sfety concerns tht re cused by the loction of overhed-cble exits nd cble routing. 7. Provide your IBM service representtive with the following informtion before the instlltion:. Whether under-floor or over-hed power-cbling scheme is to be used. b. The distnce of the rck from the power receptcles. Rised or non-rised floor considertions You cn instll the IBM XIV Storge System on rised or non-rised floor. Rised floor considertions Instlling the rcks on rised floor provides the following benefits: Copyright IBM Corp. 2008,

50 v Improves opertionl efficiency nd provides greter flexibility in the rrngement of equipment. v Increses ir circultion for better cooling. v Protects the interconnecting cbles nd power receptcles. v Prevents tripping hzrds becuse cbles cn be routed underneth the rised floor. When you instll on rised floor, consider the following fctors: v The rised floor must be constructed of fire-resistnt or noncombustible mteril. v Avoid the exposure of metl or highly conductive mteril t ground potentil to the wlking surfce when metllic rised floor structure is used. Such exposure is considered n electricl sfety hzrd. v The rised floor height must be t lest 30.5 cm (12 in.). Clernce must be dequte to ccommodte interconnecting cbles, Fibre Chnnel cble rcewys, power distribution, nd ny piping tht is present under the floor. Floors with greter rised floor heights llow for better equipment cooling. v When rised floor tile is cut for cble entry or ir supply, n extr floor tile support (pedestl) might be required to restore the structurl integrity of the pnel to the previous requirement. v The use of protective covering (such s plywood, tempered msonite, or plyron) is required to prevent dmge to floor tiles, crpeting, nd pnels while equipment is being moved into or is relocted within the instlltion site. When the equipment is moved, the dynmic lod on the csters is greter thn when the equipment is sttionry. v Concrete subfloors require tretment to prevent the relese of dust. v Use noncombustible protective molding to eliminte shrp edges on ll floor cutouts to prevent dmge to cbles nd hoses, nd to prevent csters from rolling into the floor cutout. v Sel rised-floor cble openings to prevent the escpe of chilled ir. v Pedestls must be firmly ttched to the structurl (concrete) floor by using n dhesive. For more informtion, see Prepring for rised-floor instlltion nd cbling on pge 32. Non-rised floor considertions Rised floors re preferred becuse they provide better support for the cbling nd to ensure efficient cooling for the XIV system; however, overhed cbling t the rer of the rck is vilble when the XIV system is instlled on non-rised floor. Unlike rised-floor cbling, the instlltion plnning, cble length, nd the rck loction in reltion to the cble opening t the top of the rck re criticl to the successful instlltion when using overhed cbling.

Note: Plce the opening under the XIV system, centered on the bck edge of the tile long the rer of the rck. Sizing the cutout correctly is importnt. An oversized cutout permits excessive cooling loss nd wekens the floor tile. An undersized cutout must be enlrged, which cuses n instlltion dely while the tile is replced or the cutout is enlrged. 4. To llow for ventiltion for irflow nd support system cooling requirements, hve t lest two tiles (nd preferbly more) in front of the XIV system (see Figure 8). These tiles must hve minimum of 40% perfortion. 5. If the ruggedized rck is ordered, see Ruggedized rck feture on pge 21 for dditionl floor preprtion steps. 6. If the rer-door het exchnger is ordered, see Rised floor hose requirements nd mngement on pge 82 for dditionl floor preprtion steps. Prepring for non-rised-floor instlltion nd cbling Prepre the instlltion site to ccommodte overhed cbling for minline-power cbles, customer Fibre Chnnel host cbles, network Ethernet cble, nd customer nlog phone line. Using overhed cbling provides mny of the cooling nd sfety benefits tht re provided by rised flooring in non-rised floor environment. Unlike rised-floor cbling, the instlltion plnning, cble length, nd the system loction in reltion to the cble entry point re criticl to the successful instlltion of top cble exit. Notes: v Min-power cbles re routed to the rck by the customer, nd internlly routed nd connected by n IBM service representtive. v Host-ttchment cbles re internlly routed nd connected by either the customer or by n IBM service representtive. v All remining cbles re internlly routed nd connected by n IBM service representtive.

54 Instlltion nd sfety requirements If the cbles re too long, there might not be enough room inside of the rck to hndle the extr length nd the extr cble might interfere with the servicing tsks, preventing concurrent repir. IBM Corporte Sfety restricts the servicing of your overhed equipment to mximum of 10 feet from the floor. Therefore, your power source must not exceed 10 feet from the floor nd must be within 5 feet of the top of the rck. Servicing ny overhed equipment higher thn 10 feet requires specil bid contrct. Contct your IBM Representtive for more informtion bout specil bids. Prepring for the ruggedized rck If the optionl ruggedized rck (feture code 0080) ws ordered, the customer must purchse fstening hrdwre nd prepre the loction where the kit is to be instlled before n IBM service representtive cn instll the ruggedized rck on ny of your XIV systems. Procedure The customer must perform one of the following procedures before the ruggedized rck instlltion, depending upon whether the XIV system sets on rised or non-rised floor. For either type of instlltion, work with consultnt or structurl engineer to ensure tht the site preprtions meet the requirements. v Rised floor with depth of mm (9-22 in.) 1. Consult the mnufcturer of the floor pnels tht re used t the instlltion site to ensure tht the floor pnels cn sustin concentrtion lod of 454 kg (1000 lb) per rck. More pnel supports (pedestls) might be required to restore structurl integrity of the pnels. For multiple rck instlltion, two csters might induce concentrtion lod s high s 907 kg (2000 lb) on floor pnel. 2. Obtin the service of qulified consultnt or structurl engineer to determine the pproprite hevy-duty concrete or slb-floor eyebolts. Ech eyebolt must withstnd 2268 kg (5000 lb) pull force per eyebolt. 3. Purchse four 0.5x13-in. hevy-duty concrete or slb eyebolts, with n internl dimeter of 1-3/16 in. 4.

56 Procedure To complete the rer-door het exchnger site preprtion, see Chpter 10, Plnning for the rer-door het exchnger, on pge 69 Plnning for power requirements Ensure tht your operting environment meets the c-power nd voltge requirements. The IBM XIV Storge System contins three uninterruptible power supplies nd redundnt min-power cbles tht mintin power to the XIV system in the event of n c-power loss. The three uninterruptible power supplies in the XIV system re recognized by the centrl uninterruptible power supply system in the min dt center s stndrd modern storge-system power supplies. The XIV system does not impose ny hrmful chrcteristics to the centrl uninterruptible power supply in the min dt center. The XIV system hs redundnt min-power cbles. For two-min-power-cble configurtion, you must supply power from two independent sources of electricity. Consult n IBM service representtive to discuss power source options for the four-min-power-cble configurtion. Note: Removing ll c power from the XIV system cuses n emergency shutdown. All modified dt is then sved to disks, nd the XIV system turns off within 5 minutes. Customer responsibilities v You must supply enough brnch circuits to prevent overloding from the equipment tht you instll. v You must ensure tht ech electricl outlet is correctly wired nd grounded to prevent n electricl shock. IBM responsibilities v The IBM service representtive complete severl checks, including voltge nd grounding checks before the power to the XIV system is connected. v The IBM service representtive connects power to the rcks nd initilly powers on the equipment. Power outlet requirements Ensure tht the instlltion site hs the required power outlets. Two independent power outlets re required for the two power cords tht re needed by ech XIV system. Importnt: To eliminte single point of filure, the outlets must be independent. This mens tht ech outlet must use seprte power source nd ech power source must hve its own wll circuit breker. For the most relible opertion, do not use Ground Fult Circuit Interrupter (GFCI), Erth Lekge Circuit Breker (ELCB), nd Residul Current Circuit Breker (RCCB) type circuit brekers with XIV systems. The XIV system is certified 36 IBM XIV Gen3 281x-11x, 281x-21x, nd 281x-314 Plnning Guide

57 for sfe opertion nd is complint with IEC, EN, UL, CSA stndrds. However, if lekge detection circuit brekers re required by locl electricl prctice, the brekers must be sized for lekge-current rting of 300 ma or greter to reduce the risk of server outge cused by erroneous nd spurious tripping. Power sources Severl c power source configurtions re vilble. v Two 30 A, V c, three-phse receptcles, ech connected to different power source v Two 60 A, V c, three-phse receptcles, ech connected to different power source v Two 60 A, V c, single-phse receptcles, ech connected to different power source. The IBM XIV Storge System is protected by n uninterruptible power supply for internl use. However, you cn reduce the risk of power outge by connecting the system to n externl uninterruptible power supply, bckup genertor, or both. J1 is the primry feed. This llows for better dt center power usge becuse the ATS returns to J1 if there is power to tht connector. If the three-phse, 30A ATS for non-emea (feture code 9894) is instlled nd both power feeds into the XIV system hve voltges within the opertionl tolernce, the power lod is shred cross both power feeds. If power feed fils, the ATS switches the full power lod to the remining feed. To prepre the power cbles, you must provide your IBM service representtive with the following informtion before the instlltion: v The distnce from the rck to the power receptcles. v Whether overhed or under-floor power-cbling is to be used. Power consumption This informtion describes the power consumption for prtil nd full rck configurtions. The following tble lists the power consumption for ech supported disk-drive module (DDM) cpcity with solid-stte drives (SSDs). If no SSDs re present, the power consumption is mrginlly less. The power consumption for prtil-rck configurtions is the typicl vlue nd is provided only for reference purposes. To support concurrent cpcity upgrdes, the instlltion site must provide sufficient power cpcity to support high performnce on full rck configurtion of 15 modules.

Three-phse delt instlltions (200 V V) with ATS feture code 9894 require wll circuit brekers tht hve rting of 30 A. For the most relible opertion, do not use Ground Fult Circuit Interrupter (GFCI), Erth Lekge Circuit Breker (ELCB), nd Residul Current Circuit Breker (RCCB) type circuit brekers with XIV systems. The XIV system is certified for sfe opertion nd is complint with IEC, EN, UL, CSA stndrds. However, if lekge detection circuit brekers re required by locl electricl prctice, the brekers must be sized for lekge-current rting of 300 ma or greter to reduce the risk of server outge cused by erroneous nd spurious tripping. For more informtion, see Lekge current on pge xi. v Min-power cbles with the following feture codes must meet specific design certifictions: 9891 uses bulk wire tht meets UL nd CSA sfety gency certifictions, but not the EU hrmoniztion certifiction uses bulk wire tht meets the EU hrmoniztion certifiction, but not UL nd CSA sfety gency certifictions uses bulk wire tht meets UL nd CSA sfety gency certifictions, but not the EU hrmoniztion certifiction. Emergency power-off considertions The IBM XIV Storge System does not hve n emergency power-off (EPO) switch; however, you cn connect the XIV system to room EPO switch. Note: Ntionl or locl building, electricl, fire prevention, sfety, nd other lws or regultions might ddress or control the mnner in which informtion technology equipment is instlled within certin fcilities nd environments. The ppliction of those lws or regultions might depend on considertions of fctors beyond the nture or design of the equipment to be instlled. It is customer responsibility to interpret nd identify ny lws or regultions pplicble to the instlltion of informtion technology in its environment nd to inform IBM, IBM Business Prtners, or their designted instllers of ny ctions not identified in this plnning guide tht re necessry to instll informtion technology equipment in the customer fcilities in ccordnce with such pplicble lws or regultions. A room EPO switch cn be powered by the XIV system uninterruptible power supplies for use with non-powered switch circuit brekers. The EPO circuit in the uninterruptible power supplies is considered Clss 2 circuit (UL, CSA stndrds) nd sfety extr-low voltge (SELV) circuit (IEC stndrd). Contct your IBM service representtive for more informtion bout connecting to room EPO switch. Attention: Powering off the XIV system using room EPO switch results in dt loss nd possible loss of configurtion. An IBM service representtive is required to recover n XIV system tht ws turned off using room EPO switch. If the XIV system loses c power but is not powered off using n EPO circuit, dtnd configurtion re preserved. Plnning for environmentl requirements Ensure tht the instlltion site meets ll operting environment requirements for the XIV system. Chpter 6. Instlltion site requirements 41

62 Procedure To ensure tht the instlltion site meets the requirements, complete the following steps: 1. Use dequte ventiltion, especilly during the first 120 dys of continuous opertion. Ensure tht there is n verge room outdoor intke ir rte of 0.4 ir chnge per hour. 2. Keep front nd rer of the rck cler of obstruction. 3. Verify tht you cn meet the environmentl operting requirements t the ir intke loctions. 4. Consider optimizing the ir circultion nd cooling for the rck by using rised floor, djusting the floor lyout, nd dding perforted tiles round the ir intke res. Operting environment requirements You must verify tht your operting environment is comptible with the required specifictions. With or without the rer-door het exchnger option, the ir tht enters the front door of the XIV system must meet the following requirements. Operting (powered on) v Temperture: C (50-95 F) v Reltive humidity: 20-80%, non-condensing v Mximum wet bulb temperture: 25 C (77 F) v Mximum ltitude: 2134 m (7000 ft) Non-operting (powered off) v Temperture: 5-45 C ( F) v Reltive humidity: 20-80%, non-condensing v Mximum wet bulb temperture: 27 C (80.6 F) Shipping v Temperture: C ( F) v Reltive humidity: 5-95%, non-condensing v Mximum wet bulb temperture: 29 C (84.2 F) Importnt: An XIV system tht runs continuously must be within the specified operting environment. An XIV system cn operte t the mximum llowble temperture for only short durtions, such s might occur during disk drive module or power-supply unit replcement. Continuous opertion bove the mximum temperture increses the probbility of component filure. Air enters t the front of the rck nd leves t the bck. To prevent the ir tht is leving the rck from entering the intke of nother piece of equipment, plce rcks in lternte rows, in bck-to-bck, nd front-to-front rrngement. Align the front of rcks on floor-tile sem, with full line of perforted tiles immeditely in front of the rck, nd with the ir temperture t the front of the rck less thn 27ºC (80.6ºF). System environmentl cclimtion Condenstion is norml nd nturl occurrence if pckging is removed t time of delivery, during extreme cold wether delivery times. 42 IBM XIV Gen3 281x-11x, 281x-21x, nd 281x-314 Plnning Guide

63 All IBM equipment hs been tested in climte chmbers duplicting shipping tempertures of - 40 C (- 40 F) to 60 C (140 F) nd condenstion nd frost do not impct relibility of the product. It is highly recommended tht the device not be removed from the shipping pckge for t lest 24 hours, in order to cclimte to the new temperture conditions. If there re still visible signs of condenstion fter the initil 24 hour wit period, cclimte the system without the shipping bg for n dditionl hours, or until no further visible condenstion remins. If pckge mteril removl is necessry, equipment should be plced in loction wy from ny ir vents. Air circultion nd cooling You cn tke steps to optimize the ir circultion nd cooling for your XIV system. Procedure To optimize the cooling round your XIV system, complete the following steps: 1. Instll the XIV system on rised floor, which provides incresed ir circultion for better cooling. For more informtion, see Rised or non-rised floor considertions on pge Instll perforted tiles in the front nd bck of ech bse rck nd expnsion rck s follows:. For stnd-lone bse rck, instll two fully perforted tiles in front of the bse rck nd one prtilly perforted tile t the bck of the bse rck. b. For row of rcks, instll row of perforted tiles in front of the rcks nd one or two fully perforted tiles t the bck of ech two rcks. c. For groupings of rcks, where hot isle nd cold isle lyout is used, use cold isle row of perforted tiles in front of ll rcks. For hot isles, instll perforted tile per pir of rcks. For more informtion, see Prepring for rised-floor instlltion nd cbling on pge (Model 281x-114, model 281x-214, nd model 281x-314 only) Consider using the rer-door het exchnger (feture code 0082) to further reduce the temperture of the ir tht leves the rck. The rer-door het exchnger is wter-cooled door tht is designed to remove het tht is generted from the rck before it enters the computer room. The door uses stndrd fittings nd couplings. The door removes up to 50,000 BTUs of het, which is pproximtely 15 kw, from the ir tht exits rck tht is full of servers. The rer-door het exchnger cn increse server density without incresing cooling requirements, mking the option more cost-effective solution thn dding n ir-conditioning unit. This door is n effective solution for dt center t the limit of its cooling cpcity, but tht still hs usble floor spce to dd rcks.

Risks tht re posed by the presence of excessive prticulte levels or concentrtions of hrmful gses include dmge tht might cuse the XIV system to mlfunction or cese functioning ltogether. This specifiction describes limits for prticultes nd gses tht re intended to void such dmge. The limits must not be viewed or used s definitive limits becuse numerous other fctors, such s temperture or moisture content of the ir, cn influence the impct of prticultes or environmentl corrosives nd gseous contminnt trnsfer. In the bsence of specific limits, implement prctices tht mintin prticulte or gs levels tht re consistent with the protection of humn helth nd sfety.

Use these three redundnt ports to connect to systems tht re used for mnging the XIV system using the IBM XIV Storge Mngement GUI nd IBM XIV commnd-line interfce (XCLI). These ports cn lso be used for sending emil notifictions nd SNMP trps bout event lerts, nd communiction with key servers for mnging encryption keys. Note: Use ll three connections for redundncy. If the customer uses only one pth nd the module for tht connection goes down, the bility to mnge the XIV system is lost. For informtion bout IP configurtion nd protocol requirements, see Mngement ports requirements on pge 53. Use these two virtul privte network (VPN) ports re used to connect to the XIV Remote Support Center. Note: Use both VPN connections for redundncy to void losing remote support if one of the modules fils. Use these two ports to connect the XIV system directly to notebook computer on which the GUI nd XCLI re instlled. The IBM service representtive uses these ports to initil configure nd service the XIV system. A Dynmic Host Configurtion Protocol (DHCP) server is implemented over this port. The DHCP server utomticlly ssigns IP ddresses to the notebook computer nd estblishes connection to the XIV system. To estblish connection between the notebook computer nd the XIV system, you must mnully set the Ethernet dpter on the notebook computer to use fixed ddress nd subnet msk. Do not use the Dynmic Host Configurtion Protocol (DHCP) server tht is implemented over this port. Importnt: v The technicin port must be used only by n IBM service representtive. It is not intended for customer use. v Use the technicin ports only for direct-connection to single notebook-computer. Do not connect the technicin ports to the network.

73 Mngement ports requirements The mngement ports re connected to systems tht re used for mnging the XIV system through the IBM XIV Storge Mngement GUI nd IBM XIV commnd-line interfce (XCLI). These ports cn lso be used for sending e-mil notifictions nd SNMP trps bout event lerts. To ensure redundncy in cse of interfce-module filure, the IBM XIV Storge System is mnged through three IP ddresses over Ethernet interfces. Ech IP ddress is hndled by different interfce module. The IBM XIV Storge Mngement GUI nd XCLI must be configured with ll three IP ddresses tht re defined for the XIV system. Mngement functions cn be performed through ny of the IP ddresses. These ddresses cn be ccessed simultneously by multiple clients. Users must configure the IBM XIV Storge Mngement GUI or XCLI for the set of IP ddresses tht re defined for the specific XIV system. To be resilient to network filure, ensure tht the network equipment tht provides mngement communiction is protected by n uninterruptible power supply. IP configurtion For ech of the three mngement ports, the customer or technicl ssistnt must provide the following informtion to the IBM service representtive before the instlltion is strted: v IP ddress of the port v Net msk v Defult IP gtewy v Mximum trnsmission unit (MTU) Note: All mngement IP interfces must be connected to the sme subnet nd use the sme network msk, gtewy, nd MTU. In ddition, provide the following system-level IP informtion: v IP ddress of the primry nd secondry DNS servers v IP ddress or DNS nmes of the SNMP mnger, if required v IP ddresses or DNS nmes of the SMTP servers Protocols The XIV system is mnged through dedicted mngement ports tht re running TCP/IP over n Ethernet connection. Mngement is crried out through the following protocols: v The XIV system communictes with key servers using the KMIP protocol over TCP port 5696 (if the encryption feture is enbled). v Proprietry protocols re used to mnge the XIV system from the IBM XIV Storge Mngement GUI nd IBM XIV commnd-line interfce (XCLI). This mngement communiction is over TCP port The XIV GUI nd XCLI ct s the client nd initite the connection. The XIV system cts s the server. All trffic over this port is encrypted through the Secure Sockets Lyer (SSL) protocol. v The XIV system responds to SNMP requests when sending replies to SNMP mngers. v The XIV system initites SNMP pckets when sending trps to SNMP mngers. Chpter 7. Network nd host connectivity requirements 53

74 Network configurtions v The XIV system initites SMTP trffic when sending emils for either event notifictions or for SMS gtewys. SMTP connections use port 25. v The IBM XIV Storge Mngement GUI nd XCLI communiction is Secure Sockets Lyer (SSL) encrypted, which provides security for psswords nd vrious informtion. v The mngement ports must be on different subnet thn the VPN ports tht re used for remote ccess. Host systems cn connect to n XIV system over Fibre Chnnel network or over n Ethernet network by using the Internet Smll Computer System Interfce (iscsi) protocol. Restriction: Direct ttchment between hosts nd the XIV system is not supported. Host systems must not hve mix of Fibre Chnnel nd iscsi connections to the XIV system. If your sitution requires you to temporrily mix Fibre Chnnel nd iscsi host ccess to migrte dt, you must pln crefully to void dt loss. Importnt: v Host trffic cn be directed to ny of the interfce modules. The storge dministrtor must ensure tht host connections void single points of filure. The server dministrtor must ensure tht the host worklod is dequtely blnced cross the connections nd interfce modules. This blncing cn be done by instlling the relevnt host-ttchment kit. Review the blncing periodiclly nd when trffic ptterns chnge. v Alwys employ multipthing for dt connections. If multipthing is not used, host-connection error is displyed. If there is problem on one pth in the connection nd n interfce module fils, host-connection error is lso displyed. Not ll host systems support multipth configurtion between the protocols. v Host systems must hve the pproprite host-ttchment kit instlled. Host ttchment kits re vilble for AIX, HP-UX, Linux, Solris, nd Microsoft Windows operting systems. For more informtion, see IBM XIV Host Attchment Kit ( com.ibm.help.strghosts.doc/hk-homepge.html).

In production environment, lwys connect Fibre Chnnel hosts to minimum of two seprte SAN switches in independent fbrics to provide redundncy. Severl network configurtions tht use Fibre Chnnel re techniclly possible, nd ech configurtion vries in terms of cost, flexibility, performnce, nd relibility. Three redundnt configurtions re described: 12 pths to ech volume, 6 pths to ech volume, nd miniml cbling.

The following exmple configurtions re for n XIV system over Fibre Chnnel with six interfce modules. For n XIV system over Fibre Chnnel with three interfce modules, fewer pths re used, but the principle of blncing pths cross ll interfce module still pplies. The minimum supported configurtion is pths to two different interfce modules. One pth to single interfce module is not supported. Host system cn hve s mny HBAs s needed to support the operting system, ppliction, nd overll performnce requirements. In n XIV system, ech interfce module hs four Fibre Chnnel ports. For supported interoperbility configurtions, see the System Storge Interopertion Center website ( ssic). Redundnt configurtion with six pths to ech volume Figure 13 on pge 56 illustrtes redundnt configurtion in which ll six interfce modules re ccessed by using six pths per LUN on the host. This configurtion is recommended for most generl-purpose configurtions. Host relibility during pth error recovery on certin operting systems is complicted by incresing the number of pths per LUN. For host systems with two HBAs, the six pths per LUN method is recommended. In this configurtion: v Ech host is equipped with dul HBAs. Ech HBA (or HBA port) is connected to one of two Fibre Chnnel switches. v Ech Fibre Chnnel switch hs connection to seprte Fibre Chnnel port on ech of the six interfce modules. v One host uses the first three pths per fbric, nd the next host uses the three other pths per fbric. v If fbric fils, ll interfce modules re still used. v Ech volume hs six pths.

85 Chpter 9. Plnning for remote support nd cll home Remote support connections This informtion describes wht you must know to pln for remote support nd cll home connections. XIV Remote Support Center is mngement system used by uthorized IBM service representtives to provide remote support nd problem-determintion ssistnce over secure network interfce, either before or fter prts re clled out by the internl dignostic tests of the IBM XIV Storge System. IBM uthorized personnel use remote support connections to perform rel-time problem nlysis nd isoltion. Remote ccess uses one of the following two methods: v A secure, high-speed, dedicted connection through virtul privte network (VPN) or mngement port on the XIV system. This is the preferred remote support method. v A modem nd dedicted, nlog telephone line. The security fetures differ mong these methods, including the direction of the connection. Remote ccess through dedicted network connection Remote ccess over dedicted network connection is the preferred method for obtining remote support. When using this method, the XIV system is connected to the XIV Remote Support Center through one of the virtul privte network (VPN) ports or mngement ports on the ptch pnel. The XIV Remote Support Center provides high level of security for remotely supported XIV systems through encryption, uthentiction, uthoriztion, uditing, nd field-proven security components. The XIV Remote Support Center hs three components: v The XIV remote support client is softwre tht is instlled on the XIV system nd hndles remote support connectivity. It relies on single outgoing TCP connection nd is not ble to receive inbound connections of ny kind. The XIV remote support client is controlled by using the IBM XIV commnd-line interfce (XCLI) nd strts connection, termintes connection (due to timeout or customer request), nd ttempts to reconnect when the connection is terminted unexpectedly. v The front servers serve s hub t which the XIV systems nd the remote-support bck server connect. The front servers re locted in n IBM DMZ nd receive nd mintin connections from the XIV remote support client nd the bck server. The front servers re strictly inbound nd do not initite ny outbound communiction. No sensitive informtion is stored on the front server, nd ll dt pssing through the front server from the client to the bck server is encrypted, so the front server or mlicious entity in control of front server cnnot ccess this dt. v One or more bck servers re locted within the IBM intrnet. Only IBM service representtives tht re uthorized to perform remote support of XIV systems Copyright IBM Corp. 2008,

86 cn ccess these servers. The bck server uthentictes the IBM service representtive, provides the IBM service representtive with user interfce through which to choose system to support, nd mnges the remote support session s it progresses. The IBM service representtive connects to the bck server by using Secure Shell (SSH) client or n HTTPS connection with ny browser. Requirement: To perform remote support through the Remote Support Center, the XIV system must be ble to initite n outbound SSH connection to IBM. If the XIV system does not hve direct ccess to the Internet (for exmple, due to firewll), you cn use the XIV Remote Support Proxy to fcilitte the connection to IBM. For more informtion, see the IBM XIV Storge System Remote Support Proxy Instlltion nd User's Guide. The following figure illustrtes the remote support components. Customer IBM Internet Intrnet Mngement host Customer firewll IBM firewll Front server Bck server IBM XIV Storge System xiv10033 Figure 16. Remote support components The XIV Remote Support Center uses the Secure Shell (SSH) protocol for trnsporting dt. The encryption used by SSH provides confidentility nd integrity of the trnsferred dt even over insecure mediums. To conduct remote support session, the IBM service representtive must explicitly connect to the XIV Remote Support Center bck server. The following secure remote connection process occurs when support session is opened: 1. The customer initites n Internet SSH connection to the XIV Remote Support Center. 2. The XIV Remote Support Center identifies the XIV system nd mrks it s connected. 3. The IBM service representtive connects to the XIV Remote Support Center using SSH. 4. The XIV Remote Support Center uthentictes the IBM service representtive. 5. The IBM service representtive is shown list of currently connected XIV systems tht correspond with the defined permissions, or the IBM service representtive mnully enters the seril number to view the XIV system. 6. The IBM service representtive chooses the XIV system to support. Only permitted XIV systems re displyed, nd ll ctivity is logged. 7. The fully recorded support session commences. 8. The IBM service representtive termintes the support session. 9. The XIV system disconnects from the XIV Remote Support Center. 66 IBM XIV Gen3 281x-11x, 281x-21x, nd 281x-314 Plnning Guide

87 While support session is in progress, the XIV system genertes events nd displys the system sttus on the IBM XIV Storge Mngement GUI. You cn view the process of phsing out module or the restrt of customer-visible system services s it hppens. The customer hs full control over whether to proceed with support session by using mechnisms such s timeout or force-disconnect. If session disconnects unexpectedly, the IBM service representtive cn resume the session when the XIV system next connects to the Remote Support Center. Remote ccess by modem To use the modem for remote ccess, you must connect dedicted, nlog telephone line to the modem nd give the telephone number to IBM. The telephone line must support dil-in; however, becuse the IBM XIV Storge System does not mke outgoing clls by using the modem, the telephone line does not need to support diling out. Ensure tht you use the correct connector for your country to dil in. For exmple, in Germny nd Luxembourg, use N-coded connectors. Figure 17 illustrtes the remote support connectivity by using modem. Cll home configurtion Figure 17. Remote support connectivity by modem Using cll home, you cn set up the XIV system to utomticlly send pre-filure or filure notifictions to the IBM Troubleshooting Ticketing System in the IBM Service Center. You cn lso configure the XIV system to utomticlly send lerts directly to you. Cll home cnnot ccept incoming communiction, which mens tht the IBM Service Center cnnot contct the XIV system using cll home. When certin events occur in the XIV system, cll home sends notifiction to the IBM Service Center. After receiving the notifiction, IBM service personnel nlyze the problem promptly nd tke pproprite ction. If the problem requires service, n IBM service representtive is sent to your site with ny necessry replcement prts. With ccess to the XIV system, IBM service personnel cn perform service tsks, such s viewing error logs nd problem logs or inititing trce nd dump retrievls. Cll home notifictions re sent through emil from n SMTP server. You must hve n SMTP emil system vilble tht the XIV system cn use to send outgoing cll home emils to IBM. Chpter 9. Remote support nd cll home 67

88 Importnt: It is customer responsibility to configure the SMTP emil system to enble the XIV system to send outgoing emils for the cll home function. The emil configurtion rules must not inhibit cll home emils from being sent in rel time. Emils with Importnce or X-Priority in the emil heder must not be delyed. For exmple, XIV emils must not be plced in queue for lter delivery or filtered for priority. The dministrtor must verify correct configurtion nd function of the emil system before instlltion. Filure to verify the emil system might dely the successful instlltion of the XIV system. Figure 18 shows cll home routing.

92 Prepring your site to provide wter to the het exchnger You must prepre your site to provide wter to the rer-door het exchnger before the rck cn be instlled. The following requirements must be met before the rer-door het exchnger cn be instlled: v Provide chilled, conditioned wter tht meets the specifictions. v Procure nd instll the wter supply system tht is suitble for your dt center. v Provide redundnt secondry-cooling-loop wter supply or enough room ir conditioning to hndle tolerble het lod if the function of one or more of the het exchngers is compromised. If the rer door is opened for rck mintennce or if conditioned wter supply to the door is stopped, the rck het lod is sent into the room nd must be hndled by room ir conditioning until the conditioned wter supply is restored. v Provide floor or ceiling tile cutouts or protective coverings to void tripping hzrds on non-rised floors s prt of hose mngement. Wter specifictions for the secondry cooling loop Lern bout the wter specifictions tht re required for the secondry cooling loop of your rer-door het exchnger. The wter tht is being supplied to the het exchnger must meet the following requirements; otherwise, system filures might occur over time, s result of: v Leks tht re cused by corrosion nd pitting of the metl components of the het exchnger or the wter supply system. v Buildup of scle deposits inside the het exchnger, which cn cuse the following problems: A reduction of the bility of the het exchnger to cool the ir tht is exhusted from the rck. Filure of mechnicl hrdwre, such s hose quick-connect dpter. v Orgnic contmintion, such s bcteri, fungi, or lge. This contmintion cn cuse the sme problems s described for scle deposits. Wter control nd conditioning for the secondry cooling loop The wter tht is used to fill, refill, nd supply the het exchnger must be prticle-free deionized wter or prticle-free distilled wter with pproprite controls for voiding the following issues: v Metl corrosion v Bcteril fouling v Scling Becuse of typicl wter tempertures (described in Wter delivery specifictions for secondry loops), the wter might not be ble to originte from the primry building chilled-wter system. Conditioned wter for the het exchnger must be supplied s prt of secondry, closed-loop system. Importnt: Do not use glycol solutions becuse they cn dversely ffect the cooling performnce of the het exchnger. 72 IBM XIV Gen3 281x-11x, 281x-21x, nd 281x-314 Plnning Guide

93 Mterils for the secondry cooling loops You cn use ny of the following mterils in supply lines, connectors, mnifolds, pumps, hoses, nd ny other hrdwre tht mkes up the closed-loop wter-supply system t your loction: v Copper v Brss with less thn 30% zinc content v Stinless steel 303, 304, or 316 v Ethylene Propylene Diene Monomer (EPDM) rubber, peroxide cured, non-metl oxide Mterils to void in secondry loops Do not use ny of the following mterils in ny prt of your wter supply system. v Oxidizing biocides (such s, chlorine, bromine, nd chlorine dioxide) v Aluminum v Brss with greter thn 30% zinc v Irons (non-stinless steel) Wter supply requirements for secondry cooling loops Ensure tht the following requirements re met for the system tht supplies the chilled conditioned wter to the het exchnger. Temperture Pressure Flow rte The het exchnger, supply hose, nd return hoses re not insulted nd do not hve fetures tht re designed to ddress the cretion nd collection wter from condenste. Avoid ny condition tht might cuse condenstion. The temperture of the wter inside the supply hose, return hose, nd the het exchnger must be kept bove the dew point of the loction where the het exchnger is being used. Attention: Typicl primry chilled wter is too cold for use in this ppliction becuse building chilled wter cn be s cold s 4-6 C (39-43 F). Importnt: If the system tht supplies the cooling wter is not ble to mesure the room dew point nd utomticlly djust the wter temperture, the minimum wter temperture tht must be mintined is 18 C ±1 C (64.4 F ±1.8 F). The minimum wter temperture is consistent with the ASHRAE Clss 1 Environmentl Specifiction tht requires mximum dew point of 17 C (62.6 F). See the ASHRAE document Therml Guidelines for Dt Processing Environments. You cn find informtion bout obtining this document on the ASHRAE website ( %20Processing%20Environments). The wter pressure in the secondry loop must be less thn kp (100 psi). Norml operting pressure t the het exchnger must be kp (20 psi) or less. The flow rte of the wter in the system must be in the rnge of liters (6-10 gllons) per minute. Chpter 10. Plnning for the rer-door het exchnger 73

94 Pressure drop versus flow rte for het exchngers (including quick-connect couplings) is defined s pproximtely 48 kp (7 psi) t 30 liters (8 gllons) per minute. Wter volume limits Air exposure The het exchngers hold liters ( gllons). 15 meters (50 ft) of 19 mm (0.75-in.) supply nd return hoses hold pproximtely 9.4 liters (2.5 gllons). To minimize exposure to flooding in the event of leks, the entire cooling system (het exchnger, supply hose, nd return hose) excluding ny reservoir tnk must hve mximum 15.1 liters (4 gllons) of wter. This is cutionry sttement not functionl requirement. Also, consider using lek detection methods on the secondry loop tht supplies wter to the het exchnger. The secondry cooling loop is closed loop, with no continuous exposure to room ir. After you fill the loop, remove ll ir from the loop. Air bleed vlves re provided t the top of ech het exchnger mnifold for purging ll ir from the system. Wter delivery specifictions for secondry loops The delivery system for the secondry cooling loop provides chilled wter to the rer-door het exchnger. The delivery system includes pipes, hoses, nd the required connection hrdwre to connect to the het exchnger. This informtion provides exmples for setting up the secondry cooling loop nd operting chrcteristics tht re needed to provide n dequte, sfe supply of wter to the het exchnger. The primry cooling loop is considered to be the building chilled-wter supply or modulr chiller unit. The primry cooling loop must not be used s direct source of coolnt for the het exchnger for the following resons: v If the supply wter temperture is below the room dew point, condenstion forms nd cuses dripping from the door components. v If lek develops in the door, supply hose, or return hose, lrge mount of wter is vilble. Procurement nd instlltion of the components tht re needed to crete the secondry cooling loop system re required for this design nd re your responsibility.

You cn determine the best configurtion for your instlltion by nlyzing the needs of your fcilities, or site preprtion representtive cn provide this nlysis. Flexible hoses re needed to supply nd return wter between your hrd plumbing (mnifolds nd cooling distribution units) nd the het exchnger, llowing needed movement for opening nd closing the rck rer door. Hoses re vilble tht provide wter with cceptble pressure-drop chrcteristics nd tht help prevent depletion of some corrosion inhibitors. These hoses must be mde of peroxide cured ethylene propylene diene monomer (EPDM), non-metl-oxide mteril nd must hve Prker Fluid Connectors quick-connect couplings t ech end. These couplings re comptible with the het exchnger couplings. Hose lengths from 3 to 15 meters (10-50 ft), in increments of 3 meters (10 ft), re vilble. Hoses tht re longer thn 15 meters (50 ft) might Chpter 10. Plnning for the rer-door het exchnger 81

For informtion bout supplier of these hoses, see Secondry cooling loop prts nd services informtion on pge 86. Use solid piping or tubing tht hs minimum inner dimeter of 19 mm (0.75 in.) nd the fewest possible joints between mnifold nd het exchnger in ech secondry loop. You cn use quick-connect couplings to ttch the hoses to the distribution mnifolds. You must use quick-connect couplings to ttch the hoses to the het exchnger. Hose couplings tht connect to the het exchnger must hve the following chrcteristics: v The couplings must be constructed of pssivted 300-L series stinless steel or brss with less thn 30% zinc content. The coupling size is 19 mm (0.75 in.). v The supply hose must hve Prker (mle) quick-coupling nipple, prt number SH6-63-W, or equivlent. The return hose must hve Prker (femle) quick-connect coupling, prt number SH6-62-W, or equivlent. v At the opposite (mnifold) end of the hoses, use similr quick-connect couplings. However, if you wnt to use other types of connectors, mke sure tht positive locking mechnisms re used to prevent loss of wter when the hoses re disconnected. The connections must minimize wter spill nd ir inclusion into the system when they re disconnected. You cn lso permnently ttch hoses to the mnifolds by using brbed fittings nd clmps. Rised floor hose requirements nd mngement On rised floor, hoses cn be routed under the floor tiles nd cn be brought up from beneth the rck through specil tile cutouts. The hoses re connected to the quick-connect couplings on the bottom of the het exchnger. In typicl exmple, ech het exchnger requires specil cut 0.6 m 0.6 m (2 ft 2 ft) floor tile below it with the opening outside of the rck footprint. A portion of the tile is cut wy nd correctly covered to protect ginst shrp edges. The corner opening is plced directly under the hinge side of the rck rer door. The opening size of the cut is mm wide mm long ±12.7 mm (6.0 in. wide 7.5 in. long ±0.5 in.) in the direction prllel to the door.

104 ech het exchnger still requires specil cut 0.6 m 0.6 m (2 ft 2 ft) floor tile. However, the floor tile is positioned completely within the footprint of the rck. A modified cble opening or independent hose cutout is used. Flexible hoses tht ech contin right-ngle elbow re used to route the hoses under the rck in lrge loop to llow hose movement when the door is opened nd closed. Figure 29 nd Figure 30 on pge 85 show how to route hoses under the rck with enough hose length to llow the hose to move freely s the door is opened nd closed. Note: Existing tile cutouts for electricl or other cbles cn lso be used for the hoses, if enough spce is vilble.
