IBM 750 manual IBM United States Hardware Announcement

(#7795) feature, as many as 32 LPARs are supported in a 32-core Power 750. If the PowerVM Standard or Enterprise Edition feature is installed in the system, a maximum of 10 dynamic LPARs for each physical processor can be defined, with a system maximum of 160 dynamic LPARs.

An HMC or IVM is required to manage POWER7 processor-based servers implementing partitioning. Multiple POWER7 processor-based servers can be supported by a single HMC.

If an HMC is used to manage any POWER7 processor-based server, the HMC must be a CR3, or later, model rack-mount HMC or C05, or later, deskside HMC.

When IBM Systems Director is used to manage an HMC or if the HMC manages more than 254 partitions, the HMC should have 3 GB of RAM minimum and be CR3 model, or later, rack-mount or C06, or later, deskside.

PowerVM Editions (optional)

Three optional PowerVM Edition features are now available on the Power 750: PowerVM Express Edition, PowerVM Standard Edition, and PowerVM Enterprise Edition. These are managed using built-in Integrated Virtualization Manager (IVM) software or optionally through use of an HMC.

PowerVM Standard Edition (#7794) and PowerVM Enterprise Edition (#7795) allow customers to create partitions in units of less than 1 CPU (sub-CPU LPARs) and allow the same system I/O to be virtually added to these partitions. The optional features, available for a fee, also include a software component that provides cross-partition workload management.

PowerVM Standard and Enterprise Editions offer:

•Micro-PartitioningTM(up to 10 partitions per processor, 160 per system)

•Virtualized disk and optical devices (VIOS)

•Automated CPU reconfiguration

•Real-time partition configuration and load statistics

•Support for dedicated and shared processor LPAR groups

•Support for manual provisioning of resources

At initial order entry, selecting feature number 7994 or 7995 will result in Micro- Partitioning to be enabled during manufacture and the enabling software media and publications to be shipped to the customer. When ordering feature number 7994 or 7995 as an MES, an activation key will be posted on an IBM Web site, and the customer must retrieve it and install it on the system.

Other features of PowerVM Editions:

•If any processors in a system have the Virtualization feature, all active processors must have it.

•Once the Virtualization feature is installed in a system, it cannot be removed.

•Virtual Ethernet and Virtual Storage are part of PowerVM Editions.

PowerVM Enterprise Edition also includes Live Partition Mobility, which allows for the

movement of a logical partition from one POWER6TM or POWER7 server to another with no application downtime, and Active Memory Sharing, which dynamically reallocates memory between running logical partitions on a server. Also available is PowerVM Express (#7793), designed for users looking for an introduction to more advanced virtualization features at a highly affordable price. With PowerVM Express and IVM, users can create up to three partitions on the server, leverage (VIOS), utilize Shared Dedicated Capacity to help optimize use of processor cycles, and even
