Enterprise Enablement
features
Enterprise Enablement is a Capacity on Demand Advanced
Function technology that enables the system for 5250 online transaction
processing (OLTP).
The following table describes the Enterprise
Enablement features. Full-system Enterprise Enablement means that
100% of the processor cores are enabled.

Active Memory Expansion
Active Memory Expansion
(AME) is a POWER7® function
available for use in AIX® partitions
(AIX 6.1 or later with Technology
Level 4).
With AME, memory can be expanded beyond the physical
limits of the server or of the true physical memory assigned to the AIX partition by using compression
and decompression of memory content.
Depending on your data's
characteristics and the available processor resource, you might see
expansion up to 100% of the true memory that can allow your partition
to do more work, or allow your server to run more partitions and do
more work, or both. After Active
Memory Expansion is enabled on the server, you control which AIX partitions use Active Memory Expansion and control
the degree of expansion.
You can evaluate the use of Active Memory Expansion
at no charge with Trial Capacity on Demand (Trial CoD). With Trial
CoD, the Active Memory Expansion
function can be temporarily activated for up to 60 days at no charge.
Trial Active Memory Expansion
is available once per server and it allows you to validate the benefits
your POWER7 server can realize.
Complete
the following steps to order Trial Active Memory Expansion:
-
Go to the Trial Capacity on Demand website:
Trial Capacity on Demand
-
Select the request for Active
Memory Expansion.
-
Retrieve the activation code by going to
Active Memory Expansion request

Worldwide port name renewal code
A worldwide
port name (WWPN) is a unique 64-bit identifier that is assigned to
a fibre channel node port, called an N_port. The storage area network
(SAN) administrator assigns storage to a WWPN. This scheme provides
security that limits access to storage on the SAN. The fibre channel
standards allow N_Port virtualization, called NPIV, so that one N_port
can be shared and require the generation of a unique worldwide port
name for each NPIV. Each IBM® server
that supports NPIV provides up to 64,000 unique WWPNs. When a server
indicates that there are no WWPNs remaining, customers must request
a WWPN renewal code on the website. The code enables a WWPN prefix,
which provides the first 48 bits of each WWPN and makes 64,000 more
WWPNs available on the server.
Live Partition Mobility
Trial
The Live Partition Mobility feature enables live partitions
in servers with no application downtime, resulting in better system
utilization, improved application availability, and energy savings.
You can use the Live Partition Mobility Trial version to evaluate
Live Partition Mobility free of charge for a period of 60 days. After
the trial period of 60 days, if you want to continue to use Live Partition
Mobility, you can order the PowerVM® Enterprise
Edition. If you do not upgrade to PowerVM Enterprise
Edition, at the end of the trial period, your system automatically
returns to PowerVM Standard
Edition.

Activation for 256 core LPAR
The activation
for 256 core LPAR feature permanently enables greater than 128 cores
and up to 256 cores per dedicated processor partition on the 9119-FHB POWER7 servers. Without this
feature, the largest partition that can be created is up to 128 cores.
Micropartitions, which are not affected by this feature, can only
be created with a maximum of 128 virtual processors.
Note:
The
System Partition Processor Limit (SPPL) setting must be set to the
maximum value to allow a partition to be created with more than 32
cores. If the system is running in TurboCore mode, a partition cannot
be created with more than 128 cores.

Active Memory Mirroring
for hypervisor
Active
Memory Mirroring for hypervisor is designed to ensure that system
operation continues even in the unlikely event of an uncorrectable
error occurring in main memory used by the system hypervisor. The
feature permanently activates the Active Memory Mirroring for hypervisor
capability on the 9179-MHC POWER7 servers.
When this feature is activated, two identical copies of the system
hypervisor are maintained in memory at all times. Both copies are
simultaneously updated with any changes. In the event of a memory
failure on the primary copy, the second copy is automatically called,
eliminating platform outages due to uncorrectable errors in system
hypervisor memory.
