HP Instant Capacity for HP Integrity Superdome 2 Servers

Activating HP iCAP resources

The second step of iCAP acquisition and use process is the activation of the iCAP components. This

chapter discusses the permanent activation process. See the “

Temporarily activating and deactivating

HP Instant Capacity cores with HP Temporary Instant Capacity or HP Instant Access Capacity” section

on page 13 for information on the process for temporary activation.

Figure 4: Process to permanently activate iCAP components

As shown in Figure 4, to activate an iCAP component:

1. If necessary, activate cores temporarily using IAC or TiCAP until the order for RTUs are made.

2. Order the RTUs for the iCAP components that will be activated.

3. Order the necessary HP and third-party software license upgrades that might be required for the

additional active cores.

4. For processor RTUs, after the order is processed by HP, use the iCAP commands provided to

activate the iCAP cores (

see the current Instant Capacity user’s guide). It is recommended that you

regularly check and update the iCAP inventory data for your iCAP system on the HP Utility Pricing

Solutions portal.

For memory RTUs, after the order is processed by HP, power on the iCAP blade that has the iCAP

memory to activate. Please note that RTUs must be purchased for all of the iCAP memory on the

iCAP blade.

See the “

Immediate activation of HP Instant Capacity components” section on page 6 for the process

to activate components before submitting a purchase order.

Activating multiple core processors

iCAP quad-core processors such as the Intel

Itanium

-based Tukwila processors that come with

HP Superdome 2 servers are activated on a single-core basis, however, the RTU purchase is done at

processor level that is a single processor RTU activates four cores, one or all at a time. This allows

granularity for the addition of iCAP compute power, one core at a time. Since iCAP provides the

dynamic capability of moving usage right the cores activated are not, in any sense, restricted to a

single processor.
