HP Instant Capacity (iCAP) manual Efi

	enable the creation of one or more groups (GiCAP codewords). Codewords are purchased from
	HP and retrieved from the Utility Pricing Solutions Portal.
	See also RTU, sharing rights, usage rights.
configured	A processor that is configured at the boot console handler (BCH or EFI) and whose cores are
processor	now available for activation by the Instant Capacity software.
core	The actual data-processing engine within a processor. A single processor can have multiple
	cores, and a core can support multiple execution threads.
deactivate cell	The process of changing an active cell into an inactive cell. A cell becomes inactive when a shutdown
	for reconfiguration operation is performed on its nPartition. A cell can also be deactivated by
	setting its use-on-next-bootvalue to No and then performing a reboot for reconfiguration operation
	on the nPartition, or dynamically deactivated through a cell online deactivation (cell OLD)
	without rebooting.
deactivated core	See inactive core.
deconfigured	A processor that has not yet been configured at the boot console handler (BCH or EFI). The
processor	Instant Capacity software cannot activate a processor core that is deconfigured.
EFI	Extensible Firmware Interface. The system firmware user interface that allows boot-related
	configuration changes and operations on Intel™ Itanium™-based systems. For example, EFI
	provides ways to specify boot options and list boot devices. The boot console handler (BCH)
	provides a similar function for PA-RISC systems.
Extensible	See EFI.

Interface
failback	The process of restoring a system in a failover state back to its original state.
failover	The operation that takes place when a primary service (network, storage, or CPU) fails, and
	the application continues operation on a secondary unit.
GiCAP	Global Instant Capacity. Software that enables you to move usage rights for Instant Capacity
	components within a group of servers.
Global Instant	See GiCAP.
Capacity
guest	See virtual machine.
guest OS	The operating system that is running on a virtual machine.
HA	High availability. The ability of a server or partition to continue operating despite the failure
	of one or more components. High availability requires redundant resources, such as CPU
	resources and memory, in specific combinations.
hard partition	See nPartition.
high availability	See HA.
host	1. A system or partition that is running an instance of an operating system.
	2.	The physical machine that is the VM Host for one or more virtual machines.
host name	The name of a system or partition that is running an OS instance.
host OS	The operating system that is running on the host machine.
hyper-threading	The logical CPU feature that allows multiple execution threads (logical CPUs) within a single
	core. Hyper-threading does not result in a true multicore processor, but it can add performance
	benefits. True multicore processors typically deliver much greater performance than equivalent
	hyper-threading technology.
iCAP component	See Instant Capacity component.
iCAP core	See Instant Capacity core.
inactive cell	A cell that is not available for use by software running on an nPartition. This term usually
	describes a cell that has the following status (though any cell that is not active is by definition
	inactive).
	• The slot is present and is populated.
	•	Power is enabled.
