Capacity Upgrade on Demand

In Capacity Upgrade on Demand (CUoD), processors are shipped to the customer as installed in the p5-570, and can be activated later in increments of one processor. Additional options deliver the possibility to temporarily use the processor resources that are installed in the server.

All processor cards are 2-way, with 0-way active. In an initial order of the p5-570 system, at least two processors must be activated by ordering the appropriate activation features. At least 2 GB of installed memory must be installed on each processor card independent of processor activation.

On/Off Capacity on Demand

After an On/Off Processor Enablement feature is ordered and the associated enablement code is entered into the system, customers must report On/Off usage to IBM at least monthly. This information, which is used to compute the billing data, is then provided to the sales channel, which will place an order for a quantity of On/Off Processor Day Billing features.

Reserve Capacity on Demand

The Reserve Capacity option activation is a reserve capacity for 30 processor-days of prepaid reserve. To establish processor capacity on the server, select a quantity of inactive processors to be placed in the server's shared processor pool as reserve processors. After the server recognizes that non-reserve (permanently activated) processors that are assigned or available to the uncapped partitions have been 100% utilized, use of additional processors will cause processor days (good for a 24-hour period) to be subtracted from the prepaid number of processor days.

The 30-days Reserve Capacity Processor feature is activated with FC 7956.

Dynamic Processor Sparing

When you have non-activated CUoD processors, a feature called Dynamic Processor Sparing is automatically provided. Non-activated CUoD processors are processors that are physically installed in the system but not activated. Dynamic Processor Sparing makes the system capable of disabling a failing processor and enabling a non-activated CUoD available processor.

3.1.2 Capacity Upgrade on Demand for memory

Capacity Upgrade on Demand for memory offers the ability to add memory resources and to activate in increments of 1 GB using encrypted keys.

Each of these features consists of a set of four DIMMs, with half of the memory already activated and half of the memory available for later activation. Memory can be activated in different ways using feature codes described in “Capacity Upgrade on Demand for memory feature codes” on page 54.

Permanent activation

CUoD for memory is activated in increments of 1 GB and can be activated permanently by ordering FC 7950. The FC 7950 provides 1024 MB activation for DDR1 memory.

CUoD memory features are supported only on 1.65 GHz and 1.9 GHz processor cards with DDR1 memory.
