5 PowrVault Sris Storag Array Faturs Th Dll PowrVault MD3220i is a ddicatd, high-availability (HA), nxt-gnration shard-storag array dsignd to offr improvd prformanc and capacity for storag consolidation and srvr virtualization, dploymnt flxibility and scalability. Following ar a fw advantags of using PowrVault MD3220i. MD3220i hlps rduc th ffort rquird to stor and manag your data. Ths arrays rais th bar for prformanc, flxibility and scalability. Supports up to 32 physical srvrs whn connctd to on or mor 1 Gb Ethrnt switchs Scals up to 96 hard disk driv (HDD) storag capacity with PowrVault MD1200 and/or MD1220 nclosurs Cuts managmnt complxity with a singl managmnt intrfac and a singl systm to back up Th MD3200i/MD3220i arrays offr svral advantags ovr Fibr Channl systms to support your virtual srvr nvironmnt. 1 Gb Ethrnt is a matur, wll-undrstood tchnology that is lss complicatd than Fibr Channl tchnology. Ethrnt hardwar is cost-ffctiv and radily availabl. Widsprad familiarity with Ethrnt tchnology can hlp cut training tim and costs. Th MD3200i/MD3220i arrays ar managd by nxt-gnration MD Storag Managr softwar, an intuitiv, asy-to-us clint-basd Java application. Two diffrnt managmnt paths offr asy usr intraction, vn for thos with only a basic familiarity of storag systms. Th ntrpris window fatur monitors multipl systms through a singl intrfac. Wizard-basd array managmnt hlps simplify th configuration procss. Softwar dtcts and alrts you of any problms and launchs an automatic Rcovry Guru to hlp troublshoot and rsolv th issus. MD3200i/MD3220i arrays nabl you to mix and match componnts to crat your optimal tird-storag nvironmnt. You can dploy up to 96 HDDs by simply plugging in PowrVault MD1200 and/or PowrVault MD1220 nclosurs bhind MD3200i arrays. This mans you can scal your systm with a mix of both 3.5 and 2.5 hard drivs. In dual-controllr systms, you can hot plug additional storag nclosurs without shutting down th systm. Th MD3200i/MD3220i arrays dlivr an xcllnt prformanc/pric ratio. Four iscsi ports pr controllr nabl twic th throughput compard to prvious Dll 3000i iscsi arrays. Incrasd cach sizs of up to 2GB pr controllr mt larg databas application nds. SSD support optimizs th systm for th most dmanding applications. Th MD3200i/MD3220i's optional data protction faturs includ snapshots, virtual disk copy (VDC) and slf-ncrypting drivs (SEDs) with Scur Eras. Each virtual disk supports up to ight snapshots, with a total of 128 snapshots pr systm. Ths ar typically usd whn data nds to b 5

If a driv is rmovd, th SED, which ncrypts data writtn to th driv and dcrypts data rad from th driv, "locks" to prvnt unauthorizd accss. Solution Dscription Th Dll PowrVault MD3220i is a modular disk storag xpansion nclosur for PowrEdg srvrs capabl of housing up to (24) 2.5-inch disk drivs in a singl 2U rack abl chassis. Th nclosur can support 1 Trabyt Nar-Lin SAS (7200 RPM) as wll as 10K and 15K RPM SAS drivs ranging in capacitis up to 600GB. Dll PowrVault MD3220i Product Pag Figur 1:Dll PowrVault MD3220i nclosur with (24) 2.5-inch drivs Th tstd usr profil was 0.20 IOPS pr usr with a 3GB mailbox siz. This IO profil for Exchang 2010 rprsnts about 200 mssags (snt/rcivd) pr mailbox pr day. Using 7.2K RPM drivs, w achivd mor than nough prformanc Approximatly 20% mor than th targt of 400 IOPS.

Both Exchang 2010 Srvrs would thn host 5 activ and 5 passiv db and log copis as indicatd in th topology figur abov. In total, 10 activ and 10 passiv databas and log copis wr maintaind across both storag arrays. Th ESRP-Storag program focuss on storag solution tsting to addrss prformanc and rliability issus with storag dsign. Howvr, storag is not th only factor to tak into considration whn dsigning an Exchang solution. Othr factors which affct th prformanc of th storag solution ar: Srvr procssor utilization Srvr physical and virtual mmory limitations Rsourc rquirmnts for othr applications Dirctory and ntwork srvic latncis Ntwork infrastructur limitations Clint usag profils All ths factors ar byond th scop for ESRP-Storag. Thrfor, th ESRP rquirmnts of simulating numbr of mailboxs, siz of mailbox, and mailbox profil hostd pr srvr as part of th tstd configuration may not ncssarily b viabl for som customr dploymnts.

11 Rliability Rsults A numbr of tsts in th framwork chck rliability. Th goal is to vrify th storag can handl high load for a long priod of tim.

No rrors rportd on vnt log. No Any rrors rportd in during th databas and log chcksum procss? No Storag Prformanc Rsults Th Primary Storag prformanc tsting is dsignd to xrcis th storag with maximum sustainabl Exchang for ovr two hours. Th tst shows how long it taks for th storag to rspond to an undr load. Th data blow is th sum of all of th logical driv s and th avrag of all th logical drivs latncy during th tst (which was run for six hours). Each srvr is listd sparatly and th aggrgat numbrs across all srvrs ar also prsntd.

Th first on is to masur th squntial rad rat of th databas fils, and th scond is to masur th rcovry/rplay prformanc (playing transaction logs in to th databas). Databas Rad-only Prformanc Th tst is to masur th maximum rat at which databass could b backd up via VSS. Th following tabl shows th avrag rat for a singl databas fil. MB rad/sc pr databas 36.67() MB rad/sc total pr srvr

12 Transaction Rcovry/Rplay Prformanc Th tst is to masur th maximum rat at which th log fils can b playd against th databass. Th following tabl shows th avrag rat for 500 log fils playd in a singl storag group. Each log fil is 1 MB in siz. tim to play on fil (sc) 3.02 (avg. rsp. to rplay log/avg. # of logs rplayd) Conclusion This documnt was dvlopd by Dll Inc., and rviwd by th Microsoft Exchang Product tam. Th tst rsults and data prsntd in this documnt ar basd on th tsts introducd in th ESRP tst framwork. Customrs should not quot th data dirctly for thir pr-dploymnt vrification. It is still ncssary to go through th xrciss to validat th storag dsign for a spcific customr nvironmnt. Th ESRP Storag program is not dsignd to b a bnchmarking program. Its tsts ar not dsignd for achiving th maximum throughput for a givn solution. Rathr, thy ar focusd on producing rcommndations from vndors for th Exchang application. Thrfor, th data prsntd in this documnt should not b usd for dirct comparisons among th solutions.
