configured
processor
A processor that is configured at the boot console handler (BCH or EFI) and whose cores are
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-boot value 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
processor
A processor that has not yet been configured at the boot console handler (BCH or EFI). The 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
Firmware Interface
See EFI.
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
Capacity
See GiCAP.
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 A system or partition that is running an instance of an operating system.1.
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.
IAC See Instant Access Capacity.
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.
