Configuration Guidelines
CPU Building Blocks with different clock speeds can co-exist in one system, but must be separated into hard
partitions where the CPUs have the same speed.
CPU Building Block or instant Capacity (iCAP) CPU Building Block Modules type (Tru64 UNIX or OpenVMS) must
match the base system operating system selected in Step 2, or purchase a base operating system upgrade license to
match the license with the CPU Building Block Module.

Configuration and Use of instant Capacity (iCAP) CPUs
The instant Capacity (iCAP) program gives HP customers the option to purchase add-on CPU modules at a reduced price
and install those modules in systems ready to activate instantly when needed for extra computational capacity. To use the
iCAP program for AlphaServers:
Order and install iCAP CPU modules along with Full Use CPUs. The total number of Full Use CPU Building Block
Modules plus iCAP CPU Building Bock Modules must adhere to the limits outlined above for GS1280 systems.
Use the iCAP software (supplied with the iCAP CPU Module) to set iCAP CPUs inactive. As long as the total number
of active CPUs does not exceed the number of licensed CPUs owned for the system, the owner may choose which
CPUs to designate as iCAP.
Inactive iCAP CPUs cannot include the primary CPU, CPUs responsible for hardware interrupts, CPUs being used by
an application when configuring iCAP, or a CPU connected to an I/O Building Block Drawer.
Activate the iCAP CPUs for First Use when extra capacity is needed, and then promptly purchase the iCAP
Enablement (Right-to-Use).
