Other Capacity on Demand Advanced Functions
This topic explains other Capacity on Demand (CoD) Advanced Functions such as Enterprise Enablement, Active Memory™ Expansion, worldwide port name renewal, Live Partition Mobility Trial, activation for 256-core LPAR and Active Memory Mirroring for Hypervisor.
Enterprise Enablement features
Enterprise Enablement is a Capacity on Demand Advanced Function technology that enables the system for 5250 online transaction processing (OLTP).
Active Memory Expansion
Active Memory Expansion (AME) is a 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 server can realize.
Complete the following steps to order Trial Active Memory Expansion:
- Go to the Trial Capacity on Demand website:
- Select the request for Active Memory Expansion.
- Retrieve the activation code by going to
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. 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.
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. 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.
