HP Capacity Advisor 7.2 User Guide

hardware catalog A store of data containing physical and operational attributes of current supported models of HP
servers. This data is provided to help you define realistic “what-if” systems to use in Capacity
Advisor planning scenarios.
headroom In general, the amount of a computing resource that is available on a system after all requirements
for applications on the system are accounted for.
In Capacity Advisor, requirements for applications include the utilization limits set for each
application.
See also relative headroom.
high availability See HA.
host 1. A system or partition that is running an instance of an operating system.
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.
HP iLO HP iLO. An application that allows you to remotely configure, update, and operate server blades
and standalone systems.
HP SMH HP System Management Homepage. HP SMH is a web-based interface that consolidates and
simplifies the management of a single HP-UX server. HP SMH is also available for Linux and
Microsoft® Windows® systems. HP SMH integrates with HP Systems Insight Manager, the strategic
platform for multisystem management.
hyper-threading
Intel® Hyper-Threading Technology. The ability of certain processors to create a second virtual
core that allows additional efficiencies of processing. This is not a true multi-core processor, but
it adds performance benefits. True multi-core processors typically deliver much greater performance
than equivalent hyper-threading technology.
iCAP HP Instant Capacity. The HP Utility Pricing Solutions product that allows you to purchase and
install additional processing power through the use of a two-step purchase model. Initially, you
purchase system components (cores, cell boards, memory) at a fraction of the regular price
because the usage rights are not included. These Instant Capacity components are inactive but
installed and ready for use. When extra capacity is needed, you pay the remainder of the regular
price for the usage rights to activate the components. If the regular price for the component is
reduced by the time the usage rights are purchased, the remainder price is proportionally reduced,
providing additional savings.
Earlier versions of iCAP were referred to as Instant Capacity on Demand, or iCOD.
iCAP core Also referred to as a core without usage rights, a core that is physically installed in an HP Instant
Capacity (iCAP) system but does not have usage rights and is not activated. After obtaining usage
rights, iCAP cores can be turned on by the iCAP software or during installation. Cores with usage
rights are activated with the icapmodify command (or the vparmodify command in a virtual
partition) while HP-UX is running.
inactive logical
server
A logical server that contains metadata but is not currently bound to a specific physical server or
system. Inactive logical servers that have never been activated might or might not be bound to
storage.
See also active logical server, logical server.
Insight Control
power
management
See power management.
Instant Capacity See iCAP.
Integrity VM See Integrity VM.
Integrity VM Integrity VM. A soft partitioning virtualization product that allows you to install and run multiple
systems (virtual machines) on the same physical host system (Integrity server or nPartition). The
Integrity server or nPartition acts as a VM Host for the virtual machines (also referred to as guests).
The virtual machines share a single set of physical hardware resources, yet each virtual machine
is a complete environment in itself and runs its own instance of an operating system (referred to
as a guest OS).
See also virtual machine, VM Host.
