IBM delivers enhanced capabilities for the Power S1024, Power S1022, Power S1014, Power S1022s, Power L1024, and Power L1022 servers as follows:

Active Memory Expansion (#EMBP)

AME is an innovative technology supporting the AIX® operating system that helps enable the effective maximum memory capacity to be larger than the true physical memory maximum. Compression or decompression of memory content can enable memory expansion up to 100% or more. This can enable a partition to do significantly more work or support more users with the same physical amount of memory. Similarly, it can enable a server to run more partitions and do more work for the same physical amount of memory.

AME uses CPU resource to compress or decompress the memory contents. The trade-off of memory capacity for processor cycles can be an excellent choice, but the degree of expansion varies on how compressible the memory content is. It also depends on having adequate spare CPU capacity available for this compression or decompression.

Power10 chips include a hardware accelerator designed to boost AME efficiency and use less Power core resource. The Power10 accelerator includes some minor enhancements and also leverages Power10 higher bandwidth and lower latency characteristics.

You have a great deal of control over AME usage. Each individual AIX partition can turn on or turn off AME. Control parameters set the amount of expansion desired in each partition to help control the amount of CPU used by the AME function. An IPL is required for the specific partition that is turning on memory expansion. When turned on, monitoring capabilities are available in standard AIX performance tools, such as lparstat, vmstat, topas, and svmon.

A planning tool is included with AIX, enabling you to sample actual workloads and estimate both how expandable the partition's memory is and how much CPU resource is needed. Any Power model can run the planning tool. In addition, a one-time, 60-day trial of AME is available to enable more exact memory expansion and CPU measurements. You can request the trial using the Power Capacity on Demand website.

AME is enabled by chargeable hardware feature (#EMBP), which can be ordered with the initial order of the system node or as an MES order. A software key is provided when the enablement feature is ordered, which is applied to the system node. An IPL is not required to enable the system node. The key is specific to an individual system node and is permanent. It cannot be moved to a different server.

The additional CPU resource used to expand memory is part of the CPU resource assigned to the AIX partition running AME. Normal licensing requirements apply.

One-core Base Processor Activations for scale-out capacity migration

Each new Base Processor Activation feature purchased on a scale-out Power10 server is eligible to be exchanged for a corresponding Power9 one-core Base Processor Activation feature using the Entitled Systems Support (ESS) process to help facilitate scale-out capacity migration.

IBM i System Subscription Indicator on Power S1014 server (#EHSB)

Feature EHSB provides an IBM Power S1014 server with a four-core processor module that supports a maximum system memory of 64 GB and subscription licensing for the IBM i 7.3, or later operating system version. Having feature EHSB on the order will cause the order to be routed to an IBM Project Office representative for the IBM System Subscription integrated processes.

Note: Feature EHSB is password protected. Contact for additional information.
