Reference: YE1 Overview The IBM Power 795 server is designed to help enterprises deploy cost-effective and flexible IT infrastructure while achieving exceptional application performance and increasing the speed of deployment of new applications and services. As the TM most powerful member of the IBM Power Systems family, this server provides exceptional performance, massive scalability, and energy-efficient processing for a full range of complex, mission-critical applications with the most demanding computing requirements. The innovative IBM Power 795 server with POWER7 processors is a symmetric multiprocessing (SMP), rack-mounted server. Equipped with either eight 32-core or 2-core processor books, the Power 795 server can be deployed in 2-core to 25-core, multiprocessing (SMP) configurations. With up to TB of buffered DDR3 memory and extensive I/O support, the Power 795 server can scale rapidly and seamlessly to address the changing needs of today's data center. With advanced PowerVM virtualization, EnergyScale technology, Capacity on Demand (CoD) options, and Active Memory Expansion options, the Power 795 helps businesses take control of their IT infrastructure and confidently consolidate multiple applications for the UNIX, IBM i, and Linux operating systems onto a single system. TM TM Each of the eight POWER7 processor books in a model 795 server has -bit architecture integrated into each of four single-chip modules (SCMs). Each SCM contains either a -core or -core CoD processor. The model 795 server is available starting as low as six active cores and increments one core at a time through builtin CoD functions. Processor books with -core SCMs allow server capacity to scale from six active cores to 192 active cores; whereas, books with -core SCMs allow server capacity to scale from active cores to 25 active cores. Also, the maximum number of active cores per partition using -core SCMs can be increased to 25cores when feature number 5 is installed. What makes the IBM high-end servers truly unique is the ability to switch between its standard throughput mode and its unique, optimized TurboCore mode, where performance per core is boosted with access to both additional L3 cache and additional clock speed. In standard mode, each -core SCM operates at. GHz with 32 MB of L3 cache and can scale up to 25-cores. When operating in TurboCore mode, each -core SCM operates with up to four active cores per SCM at.25 GHz and 32 MB of L3 cache, twice the L3 cache per core available in standard mode. In TurboCore mode, the Power 795 server can scale up to cores. Each -core SCM operates at 3.72 GHz only in standard mode with MB of L3 cache per core. the -core and -core SCMs are supported by 25 KB of L2 cache per core. The POWER7 DDR3 memory uses a new memory architecture to provide greater bandwidth and capacity. This enables operating at a higher data rate for large memory configurations. Each new POWER7 processor book can support up to 32 DDR3 DIMMs running at 1, MHz. A full system can contain up to TB of memory. Memory can be augmented with optional Active Memory Expansion.

Contact your IBM representative or IBM Business Partner for more information. IBM United States Hardware Announcement

6 Processor book #7 can run in standard (. GHz) or TurboCore mode (.25 GHz). TurboCore mode restricts the system from utilizing all of the processor cores in the system. A maximum of half of the physical cores can be utilized when in TurboCore mode. To utilize more than 5% of the processors present in the system, switch the system out of TurboCore mode and reboot the system. Switching in and out of TurboCore requires a system reboot. The entire system must operate in either standard or TurboCore mode. Processor book #72 is a 2-core, CoD processor. Processor book #72 runs only in standard mode at 3.72 GHz. CoD activations will activate processor cores only in the system serial number where they are purchased. If you move a processor book to another system, the processor cores may not be functional in that system until arrangements are made to move the processor activations or purchase additional processor activations. Contact your IBM representative or IBM Business Partner for more information. When using /32-core processor book (#7), a minimum of 25% of the available processor cores within a system must be activated, or a system minimum of 2 activations, whichever is greater. When using /32-core processor book (#7), the following minimum system processor cores activated using either #713 (1-core activation) or #717 (core activations) are: One processor book installed requires at least 2 permanently activated cores. Two processor books installed require at least 2 permanently activated cores. Three processor books installed require at least 2 permanently activated cores. Four processor books installed require at least 32 permanently activated cores. Five processor books installed require at least permanently activated cores. Six processor books installed require at least permanently activated cores. Seven processor books installed require at least 5 permanently activated cores. Eight processor books installed require at least permanently activated cores. When using /2-core processor book (#72), the following minimum system processor cores activated using either #7 (1-core activation) or #71 (core activations) are: One processor book installed requires at least 2 permanently activated cores. Two processor books installed require at least 2 permanently activated cores. Three processor books installed require at least 2 permanently activated cores. Four processor books installed require at least 2 permanently activated cores. Five processor books installed require at least 3 permanently activated cores. Six processor books installed require at least 3 permanently activated cores. Seven processor books installed require at least 2 permanently activated cores. Eight processor books installed require at least permanently activated cores. A minimum of 32 GBs total or 2 GBs of memory for each active processor core must be activated, whichever is greater. For a server with one #72 processor book installed with six active processors, a minimum of 32 GBs of memory must be activated. For a server with eight #7 processor books installed with activated processors, a minimum of GBs of memory must be activated. The maximum number of active cores in an AIX partition (LPAR) may be increased to 25-cores for the 32-core processor book, #7, when feature code 5 is installed, "AIX Enablement for 25-cores LPAR". Without #5 installed, the maximum number of active cores in a #7 partition is equal to 32-cores but not greater than -cores when four or more processor books are installed. Installing #5 as a MES order will require the system to reboot before the larger partition size of 25-cores will be recognized. Table 1.

Purchase will require lab services pre-analysis as a prerequisite to shipment. RPQ A135 "Large LPAR Lab Assessment" must be ordered for lab services pre-analysis. Software key requires feature number 5 to be installed. Memory Memory features include a total of four DIMMs. There is a required plug location for every memory feature attached to a processor. Each processor book has 32 memory DIMM slots ( memory features) and must be populated with POWER7 DDR3 Memory DIMMs. Each processor book requires a minimum of two memory features installed ( DIMMs). The minimum initial order quantity of a memory feature must equal two ( DIMMs). All POWER7 memory features must be purchased with sufficient permanent memory activation features so that the minimum system memory is at least 5% active for all memory features with the exception of features 52 and 221. For two /32 GB (#5), the minimum memory activated is 32 GBs. Although the minimum memory order default is x feature 51, the required minimum is that two memory features be installed for each processor book ordered. There is also a recommended system minimum 2 GBs of active memory for each active processor core. When only one processor book is installed (#7, #72), a minimum of 2 cores must be activated. Therefore, the minimum amount of memory activated for one processor book is GBs, which is the only exception to the above minimum of 32 GBs being activated for two /32 GB feature 5 memory features in a processor book. Minimum activations ordered with all newly purchased / GB memory (#52) is 75%, which equals 9/ GB per each 52 feature purchased. However, the minimum activations ordered with newly purchased feature 52 memory shall not exceed 75% of the total available feature 52 installed system memory. This allows newly ordered feature 52 memory to be purchased with less than 9/ GBs per each 52 feature ordered when the system activations currently installed exceed 75% of existing feature 52 capacity. Minimum activations ordered with all newly purchased /2 GB memory (#221) is 75%, which equals 7/2 GBs per each feature 221 purchased. However, the minimum activations ordered with newly purchased feature 221 memory shall not exceed 75% of the total available feature 221 installed system memory. This allows newly ordered feature 52 memory to be purchased with less than 7/2 GBs per each feature 221 ordered when the system activations currently installed exceed 75% of existing feature 221 capacity. Memory features 5, 51, and 52 can be mixed within the same POWER7 processor book. Memory CoD activations will activate memory hardware only in the system serial number where they are purchased. If you move memory hardware to another system, the memory may not be functional in that system until arrangements are made to move the memory activations or purchase additional memory activations. Contact your IBM representative or IBM Business Partner for more information. It is recommended that memory be installed evenly across all processor books in the system. Balancing memory across the installed processor books allows memory access in a consistent manner and typically results in the best possible performance for your configuration.

8 Plans for future memory upgrades should be taken into account when deciding which memory feature size to use at the time of initial system order. PowerCare service Included with Power 795 systems is a PowerCare services option, which entitles you to choose one of several high-value technical service offerings from IBM to complement and assist in the deployment of a new Power 795 system. This option is provided at no additional charge. By leveraging the skills, experiences, and proven methodology of IBM Systems Lab Services professionals, you can potentially increase the efficiency and quality of your complex data center operations. The PowerCare option is included with new Power 795 systems and MES upgrades into a Power 795. PowerCare options are reviewed during the Power 795 Technical and Delivery Assessment (formerly known as the Systems Assurance Review). The customer has up to 9 days from the install date of the Power 795 to select a PowerCare offering. Delivery of the selected service must be completed within nine months of the install date of the Power 795 system. For more details on available PowerCare options, visit Model upgrades Customers with installed -FHA servers can increase their computing power by ordering a model conversion to the Power 795 server. You can upgrade the IBM TM POWER -FHA server to an IBM POWER7 - server with Power 795 processors and POWER7 DDR3 memory. For upgrades from POWER processorbased systems, IBM will install new Power 795 processor books and memory in the -FHA CEC frame along with other POWER7 components. The current POWER Bulk Power Distribution and Regulator Assemblies will not be replaced. From the Power 595 CEC frame, POWER BPR (#333), BPD (#33), X PCI-X (#5797 and #579) and PCIe (#53 and #573) I/O drawers will be allowed to migrate to the upgraded Power 795 CEC. Any older RIO/HSL I/O drawers such as the #579, #595, #59/529, #5 used in -FHA will not attach. Also, any PCI adapters contained in older RIO/HSL drawers which are supported on the Power 795 will need to be moved to a X I/O drawer or be replaced by newer I/O. Along with PCI-X and PCIe I/O drawers migrating to the new upgraded 795, both the Power inch self-powered expansion and bolt-on racks (#953 and #95) will also be allowed to migrate. Also, the 19-inch, 2M expansion rack (#553) will migrate with the above model upgrade. Also, the 19-inch, 2EIA SAS I/O drawer (#5) and TotalStorage EXP2 Disk Drawer (SCSI - #57) will be allowed to migrate with the 19-inch rack. te that new #57 Disk can not be ordered against the - and thus only existing #57 drawers can be moved to the Power 795.

The On/ Off enablement features should be removed from the configuration file before the MES order is started to initiate the model upgrade. Any temporary use of processors or memory owed to IBM on the existing system must be paid before installing the new Power 795 model. Use up an existing credit days/minutes before upgrading as there is no product structure to convert Power 595 processor or memory days or processor minutes to Power 795 units. PowerVM PowerVM is available on the -: PowerVM Editions are available as a hardware feature (#793 for Standard Edition, #2 for Enterprise Edition). Clients select the feature that provides the level of virtualization appropriate for their workloads. Micro-Partitioning allows a single processor core to be shared by up to logical partitions. Virtual I/O Server (VIOS) is a single-function appliance that resides in an IBM TM POWER5, POWER, or POWER7 processor-based partition. It facilitates the sharing of physical I/O resources between client partitions (AIX V5.3 or later, IBM i V.1, or Linux) within the server. VIOS provides virtual SCSI targets and shared Ethernet adapter (SEA) virtual I/O to client LPARs. Virtual SCSI (VSCSI) enables the sharing of physical storage adapters (SCSI and Fibre Channel) and storage devices (disk and optical) between logical partitions. With virtual networking, a shared Ethernet adapter enables connectivity between internal and external virtual LANs (VLANs); virtual Ethernet provides high-speed connections between partitions. PowerVM Lx runs most x Linux applications, but PowerVM Lx cannot run applications that: Directly access hardware devices (for example, 3D graphics adapters) Require nonstandard kernel module access or use kernel modules not provided by the Linux operating system distribution Do not use only the Intel IA-32 instruction set architecture as defined by the 1997 Intel Architecture Software Developer's Manual consisting of Basic IBM United States Hardware Announcement 1-15

Use real-mode or 1-bit instructions. Are x Linux specific system administration or configuration tools. A full list of qualifications can be found at qual.html Live Partition Mobility, available only with PowerVM Enterprise Edition, will allow you to move a running AIX or Linux LPAR from one physical server to another with no downtime if both servers are using POWER or POWER7 processors. This capability can be used to evacuate workloads from a system before performing scheduled maintenance, to move workloads across a pool of different physical resources as business needs shift, and to move workloads away from underutilized machines so that they can be powered off to save on energy and cooling costs. Active Memory Sharing allows memory to be dynamically moved between running partitions for optimal resource usage. PowerVM Editions: PowerVM Standard Edition (#793) supports up to partitions per core, VIOS, PowerVM Lx, and multiple shared processor pools. PowerVM Enterprise Edition (#2) adds support for Live Partition Mobility and Active Memory Sharing. Other PowerVM technologies include: Workload Partitions (WPARs): Provide isolated instances on top of a single AIX.1, or later, image. Live Application Mobility (available with WPAR Manager): Provides the movement of a running AIX application from one server to another. System Planning Tool: Simplifies the process of planning and deploying Power Systems LPARs and virtual I/O. System control Each 795 server must be connected to an HMC for system control, LPAR, Capacity Upgrade on Demand, and service functions. The HMC is capable of supporting multiple POWER servers. Each 795 server can be connected to two HMCs for redundancy, if desired. The 795 is connected to the HMC through Ethernet connections to the front and rear Bulk Power Hub (BPH) in the CEC Bulk Power Assembly. IBM United States Hardware Announcement

15 On Demand business computing CoD for processors CoD for processors is available for the Power 795 servers. CoD for processors allows inactive processors to be installed in the 795 server and can be permanently activated by the customer as required. Power 795 offers two different processor books, #7 and #72; where #7 is a 32-core CoD processor book and #72 is a 2-core book. Each processor book has initially zero cores active that can be permanently activated using CoD activation features, #7, #71, #713, #717. Permanent single-core activations for #7 is done with #713 and -core activations with #717. Permanent single-core activations for #72 is done with #7 and -core activations with #71. The minimum number of permanently activated processors within a system is based on the number of processor books installed. A minimum of 25% of the available processor cores within a system must be activated, or a minimum of 2 activations, whichever is greater. When using /32-core processor book (#7), the following minimum system processor cores activated using either feature 713 (1-core activation) or feature 717 (-core activations) are: One processor book installed requires at least 2 permanently activated processor cores. Two processor books installed require at least 2 permanently activated processor cores. Three processor books installed require at least 2 permanently activated processor cores. Four processor books installed require at least 32 permanently activated processor cores. Five processor books installed require at least permanently activated processor cores. Six processor books installed require at least permanently activated processor cores. Seven processor books installed require at least 5 permanently activated processor cores. Eight processor books installed require at least permanently activated processor cores. When using /2-Core processor book (#72), the following minimum system processor cores activated using either feature 7 (1-core activation) or feature 71 (-core activations) are: One processor book installed requires at least 2 permanently activated processor cores. Two processor books installed require at least 2 permanently activated processor cores. Three processor books installed require at least 2 permanently activated processor cores. Four processor books installed require at least 2 permanently activated processor cores. Five processor books installed require at least 3 permanently activated processor cores. Six processor books installed require at least 3 permanently activated processor cores. Seven processor books installed require at least 2 permanently activated processors. Eight processor books installed require at least permanently activated processor cores. Additional CoD processor cores are activated in increments of one by ordering the appropriate activation feature number. If more than one processor is to be activated at the same time, the activation feature should be ordered in multiples, IBM United States Hardware Announcement

16 or increments of -core activations can be ordered using #713 with #7 processor book and #71 with #72 processor book. After receiving an order for a CoD processors activation, IBM will provide you with a 32-character encrypted key. This key is entered into the system to activate the desired number of additional processors. CoD processors that have not been activated are available to the 795 server for dynamic processor sparing when running a supported level of the AIX operating system. If the server detects the impending failure of an active processor, it will attempt to activate one of the unused CoD processors and add it to the system configuration. This helps to keep the server's processing power at full strength until a repair action can be scheduled. On/Off CoD On/Off CoD enables processors or memory to be temporarily activated in fullday increments as needed. Charges are based on usage reporting collected monthly. Processors and memory may be activated and turned off an unlimited number of times, whenever you want additional processing resources. This offering provides a system administrator an interface at the HMC to manage the activation and deactivation of resources. A monitor that resides on the server logs the usage activity. You must send this usage data to IBM monthly. A bill is then generated based on the total amount of processor and memory resources utilized, in increments of Processor and Memory (1 GB) Days. Before using temporary capacity on your server, you must enable your server. To do this, order an enablement feature (MES only) and sign the required contracts. If a Power 795 server uses the IBM i operating system in addition to AIX or Linux, you must inform the sales team placing the billing feature order which operating system caused the temporary On/Off CoD processor use so that the correct feature can be used for billing. The following features are used to order enablement codes and support billing charges on the Power 795: Model Processor Feature On/Off CoD Processor Enablement Feature Model Memory Features On/Off CoD Memory Enablement Feature AIX/Linux On/Off CoD Processor Billing Feature IBM i only On/Off CoD Processor Billing Feature On/Off CoD Memory Billing Feature Trial CoD Trial CoD is a function delivered with all Power Systems servers supporting CUoD resources. Those servers with stand-by CUoD processors or memory will be capable of using a one-time, no-cost activation for a maximum period of 3 consecutive days. This enhancement allows for benchmarking of CUoD resources or can be used to provide immediate access to stand-by resources when the purchase of a permanent activation is pending. Trial CoD is a complimentary service offered by IBM. Although IBM intends to continue it for the foreseeable future, IBM reserves the right to withdraw Trial CoD at any time, with or without notice. You can request either a Standard or an Exception Trial by visiting IBM United States Hardware Announcement

17 The On/Off CoD process consists of three steps: Enablement, Activation, and Billing 1. On/Off CoD enablement: Description Before requesting temporary capacity on a server, you must "enable" it for On/Off CoD. To do this, order an enablement feature (MES only) and sign the required contracts. IBM will generate an enablement code, mail it to you, and post it on the Web for you to retrieve and enter on your server. A processor enablement code lets you request up to 3 processor days of temporary capacity. If you have reached the limit of 3 processor days, place an order for another processor enablement code to reset the number of days you can request to 3. A memory enablement code lets you request up to 999 memory days of temporary capacity. If you have reached the limit of 999 memory days, place an order for another memory enablement code to reset the number of days you can request to 999. On/Off CoD enablement: Step-by-Step Prerequisite 1: Sales channel (IBM Business Partner) must sign one of the following contracts, if applicable: IBM Business Partner Agreement, Distributor Attachment for On/Off Capacity On Demand IBM Business Partner Agreement for Solution Providers -- Attachment for On/ Off CoD IBM Business Partner Agreement -- Attachment for On/Off CoD Prerequisite 2: Sales channel (IBM Business Partner or IBM Direct) must register at the following Web site a. Step 1: You initiate the request for On/Off CoD use by requesting Sales channel to enable the machine for temporary capacity. b. Step 2: You must complete and sign the following contracts. It is the Sales Channel's responsibility to return the signed contract to the responsible CSO organization and fax a copy to IBM at Required: IBM Customer Agreement, Attachment for On/Off Capacity On Demand; IBM Supplement for On/Off Capacity On Demand -- Optional: IBM Addendum for On/Off Capacity On Demand Alternative Reporting c. Step 3: Sales channel places an order for processor or memory enablement features. d. Step : Sales channel updates the Web site registration data (see prerequisite 2 above) with information about the customer machine being enabled for temporary capacity. te: The order for an enablement feature will not be fulfilled until this step is completed. e. Step 5: IBM generates an enablement code and mails/posts it. f. Step : You retrieve the enablement code and applies it to the server. 2. On/Off activation requests: Description When On/Off CoD temporary capacity is needed, simply use the HMC menu for On/Off CoD and specify how many of the inactive processors or GBs of memory you would like temporarily activated for some number of days. You will be billed for the days requested, whether the capacity is assigned to partitions or left in the shared processor pool. At the end of the temporary period (days you requested), you must ensure the temporarily activated capacity is available to be reclaimed by the server (not assigned to partitions), or you will be billed for any unreturned processor days (per the contract you signed). IBM United States Hardware Announcement

18 On/Off CoD activation requests: Step-by-step When there is a need for temporary capacity, use the On/Off CoD temporary capacity HMC menu for the server and specify how many of the inactive processors or GBs of memory you would like temporarily activated for some number of days. The user must assign the temporary capacity to a partition (whether or not the machine is configured for LPAR) to begin using temporary capacity. 3. On/Off CoD billing: Description The contract, signed by the you before receiving the enablement code, requires On/Off CoD user to report billing data at least once a month (whether there is activity or not). This data is used to determine the proper amount to bill at the end of each billing period (calendar quarter). Failure to report billing data for use of temporary processor or memory capacity during a billing quarter will result in default billing equivalent to 9 processor days of temporary capacity. The Sales channel will be notified of your requests for temporary capacity. As a result, the Sales channel must order a quantity of billing features (one feature for each billable processor and memory day reported). On/Off CoD billing: Step-by-step a. You must report billing data (requested and unreturned processor and memory days) at a minimum of once per month either electronically or via fax (stated requirement in the signed contract). b. At the end of each billing period (calendar quarter), IBM will process the accumulated data reported and notify the Sales channel for proper billing. c. The Sales channel places an order for the appropriate quantity of billing features (one processor billing feature ordered for each processor day used, or one memory day for each memory day utilized). d. IBM will ship a billing notice (notifies you of billing actions) to the ship-to address on the order as part of the fulfillment process. e. You pay the Sales channel and the Sales channel pays IBM for the fulfillment of the billing features. Utility CoD Registration and usage reporting for Utility CoD is made using a public Web site and payment is based on reported usage. Utility CoD requires PowerVM Standard Edition (#793) or PowerVM Enterprise Edition (#2) to be active on the -. For more information regarding registration, enablement, and use of Utility CoD, visit Utility CoD autonomically provides additional processor performance on a temporary basis within the shared processor pool. Utility CoD enables you to place a quantity of inactive processors into the server's Shared Processor Pool, which then becomes available to the pool's resource manager. When the server recognizes that the combined processor utilization within the shared pool exceeds % of the level of base (purchased/active) processors assigned across uncapped partitions, then a Utility CoD Processor Minute is charged and this level of performance is available for the next minute of use. If additional workload requires a higher level of performance, the system will automatically allow the additional Utility CoD processors to be used and the system automatically and continuously monitors and charges for the performance needed above the base (permanent) level.

19 Model Utility Billing Processor Feature Utility CoD Feature Description Processor Processor Processor Processor minutes minutes minutes minutes for for for for #7 (/32-core) #72 (/2-core) #7, IBM i #72, IBM i Capacity backup offering for DR (AIX/Linux/IBM i) POWER 795 capacity backup for DR capability The IBM Power 795 Capacity Backup (CBU) solution for Disaster Recovery (DR) offers an offsite, DR machine at an affordable price with a choice of two CBU features, #75 or #752. Power 795 CBU offerings allow flexibility in selecting active and stand-by processors in four configurations using equivalents of the two standard Power 795 processor books, #7 or #72. CBU feature #75 offers four different maximum stand-by configurations using a /32-core, equivalent #7 processor book. Each #75 configuration provides multiple increments of On/Off CoD billing credits. Each of the CBU offerings provides a fixed number of permanently activated processors. CBU #75 allows either /, /, /192 or 1/25 permanently activated cores. te: This is different from the 25% minimum activation required with orders for the standard #7 processor book. CBU feature #752 offers stand-by configurations using a /2-core, equivalent #72 processor book. Each #752 configuration provides multiple increments of 13 On/Off CoD billing credits. CBU #752 allows either 3/, /9, 9/ or /192 permanently activated cores. te: This is different from the 25% minimum activation required with orders for the standard #72 processor book. CoD activations of Power 795 CBU servers require the On/Off CoD Enablement function discussed under "On/Off CoD Enablement" in the On/Off CoD section. The On/Off CoD enablement code does not ship with the CBU server as customer contracts and Sales Channel registration are required prior to processing an MES order for On/Off CoD enablement feature #7971. The On/Off CoD usage days provided with the CBU server will be reflected as credits in the quarterly On/Off CoD Usage and Billing report, which is distributed to the Sales Channel that registers the CBU system for On/Off CoD. The no-charge processor days provided with the #75 and 752 are intended to be available for use in a disaster, other fail-over situations, or for fail-over testing; nevertheless, they can be used as you see appropriate. However, when the nocharge processor days provided with the CBU system are exhausted, additional temporary CoD processor-days may be purchased under the same terms and conditions available when ordering the Processor Billing feature for processor feature #7 or #72. Temporary on/off memory (gigabyte days) are not provided with CBU features #75 and #752. On/off memory can be enabled for a CBU server by ordering On/Off Memory Enablement #7973. The stand-by processors of #75 and #752 cannot be permanently activated. After exhausting the On/Off CoD billing credits provided with the CBU offering, additional On/Off CoD usage days may be purchased at regular On/Off CoD billing feature prices. Regular use of stand-by processors outside a disaster may be costly. For more information on CoD usage, visit IBM United States Hardware Announcement

20 Capacity BackUp Offering for IBM i (applies to IBM i only) The Power 795 server's Capacity BackUp (CBU) designation can help meet your requirements for a second system to use for backup, high availability, and disaster recovery. You can temporarily transfer IBM i processor license entitlements and 525 Enterprise Enablement entitlements purchased for a primary machine to a secondary CBU-designated system. Temporarily transferring these resources instead of purchasing them for your secondary system may result in significant savings. Processor activations cannot be transferred. The CBU specify feature #9 is available only as part of a new server purchase or during an MES upgrade from an existing system to a -. Certain system prerequisites must be met and system registration and approval are required before the CBU specify feature can be applied on a new server. The CBU for IBM i specify #9 can be used with any of the Power 795 processor book features, including the CBU for DR. However, temporary transfers of IBM i licensing and 525 entitlements are to permanently activated processors. The CBU for DR processor books #75/752 have relatively few permanently activated processors lessening the usefullness of CBU of IBM i in this situation. Standard IBM i terms and conditions do not allow either IBM i processor license entitlements or 525 OLTP (Enterprise Enablement) entitlements to be transferred permanently or temporarily. These entitlements remain with the machine they were ordered for. When you register the association between your primary and onorder CBU system, you must agree to certain terms and conditions regarding the temporary transfer. After a CBU system designation is approved and the system is installed, you can temporarily move your optional IBM i processor license entitlement and 525 Enterprise Enablement entitlements from the primary system to the CBU system when the primary system is down or while the primary system processors are inactive. The CBU system can then better support fail-over and role swapping for a full range of test, disaster recovery, and high availability scenarios. Temporary entitlement transfer means that the entitlement is a property transferred from the primary system to the CBU system and may remain in use on the CBU system as long as the registered primary and CBU system are in deployment for the high availability or disaster recovery operation. The primary system for a Power 795 server is a: 795 (-) 7 (9179 MHB) 595 (-FHA) 595 (9-595) These systems have IBM i software licenses with an IBM i P5 software tier or higher. The primary machine must be in the same enterprise as the CBU system. Before you can temporarily transfer IBM i processor license entitlements from the registered primary system, you must have more than one IBM i processor license on the primary machine and at least one IBM i processor license on the CBU server. An activated processor must be available on the CBU server to use the transferred entitlement. You may then transfer any IBM i processor entitlements above the minimum one, assuming the total IBM i workload on the primary system does not require the IBM i entitlement you would like to transfer during the time of the transfer. During this temporary transfer, the CBU system's internal records of its total number of IBM i processor license entitlements are not updated, and you may see IBM i license noncompliance warning messages from the CBU system. Such messages that arise in this situation do not mean you are not in compliance. IBM United States Hardware Announcement

21 Before being able to temporarily transfer 525 entitlements, you must have more than one 525 Enterprise Enablement entitlement on the primary server and at least one 525 Enterprise Enablement entitlement on the CBU system. You may then transfer the entitlements that are not required on the primary server during the time of transfer and that are above the minimum of one entitlement. For example, if you have an eight-core Power 795 as their primary system with four IBM i processor license entitlements (three above the minimum) and two 525 Enterprise Enablement entitlements (one above the minimum), they can temporarily transfer up to three IBM i entitlements and one 525 Enterprise Enablement entitlement. During the temporary transfer, the CBU system's internal records of its total number of IBM i processor entitlements is not updated, and they may see IBM i license noncompliance warning messages from the CBU system. If your primary or CBU machine is sold or discontinued from use, any temporary entitlement transfers must be returned to the machine on which they were originally acquired. For CBU registration and further information, visit Active Memory Expansion Active Memory Expansion is an innovative POWER7 technology that allows the effective maximum memory capacity to be much larger than the true physical memory maximum. Sophisticated compression/decompression of memory content can allow memory expansion up to %. This can allow a partition to do significantly more work or support more users with the same physical amount of memory. Similarly, it can allow a server to run more partitions and do more work for the same physical amount of memory. Active Memory Expansion is available for partitions running AIX.1, or later. Active Memory Expansion uses CPU resource to compress/decompress the memory contents. The trade off of memory capacity for processor cycles can be an excellent choice, but the degree of expansion varies based on how compressible the memory content is, and it also depends on having adequate spare CPU capacity available for this compression/decompression. Tests in IBM laboratories using sample workloads showed excellent results for many workloads in terms of memory expansion per additional CPU utilized. Other test workloads had more modest results. You have a great deal of control over Active Memory Expansion usage. Each individual AIX partition can turn on or turn off Active Memory Expansion. Control parameters set the amount of expansion desired in each partition to help control the amount of CPU used by the Active Memory Expansion function. An IPL is required for the specific partition that is turning memory expansion on or off. Once turned on, there are monitoring capabilities in standard AIX performance tools such as lparstat, vmstat, topas, and svmon. A planning tool is included with AIX.1 Technology Level allowing you to sample actual workloads and estimate both how expandable the partition's memory is and how much CPU resource is needed. Any model Power System can run the planning tool. In addition, a one-time, -day trial of Active Memory Expansion is available to provide more exact memory expansion and CPU measurements. The trial can be requested using the CoD Web page Active Memory Expansion is enabled by a chargeable hardware feature, #79, which can be ordered with the initial order of the server or as an MES order. A software key is provided when the enablement feature is ordered that is applied to the server. An IPL is not required to enable the server. The key is specific to an individual server and is permanent. It can not be moved to a different server. The additional CPU resource used to expand memory is part of the CPU resource IBM United States Hardware Announcement
