HP Capacity Advisor 7.2 User Guide

associated with a system may have historical data associated with it from Capacity Advisor or
Global Workload Manager (gWLM). As with any workload, the historical data will be lost if the
workload is deleted.
When migrating a workload from one system to another, it may be useful to park the workload
(removing the association with the original system) until the new system becomes available. This
preserves the historical data for the workload across the migration.
partition 1. A subset of server hardware that includes core, memory, and I/O resources on which an
operating system (OS) can be run. This type of partitioning allows a single server to run an
OS independently in each partition with isolation from other partitions.
See also nPartition, virtual partition.
peak The highest utilization value in the selected time interval.
policy A collection of rules and settings that control workload resources managed by Global Workload
Manager (gWLM). For example, a policy can indicate the minimum and maximum amount of
CPU resources allowed for a workload, and a target to be achieved.
A single policy can be associated with multiple workloads.
power
management
Insight Control power management. An integrated power monitoring and management application
that provides centralized control of server power consumption and thermal output at the level of
the data center. It extends the capacity of data centers by enabling you to reduce the amount of
power and cooling required for ProLiant and Integrity servers.
PRM Process Resource Manager. An HP product used to dynamically divide resource utilization among
different applications and users PRM controls the amount of resources that processes use during
peak system load.
Process Resource
Manager
See PRM.
processor The hardware component that plugs into a processor socket. Processors can contain more than
one core.
See also core.
processor module The packaging of one or more processors to connect into a single socket on the system bus.
Examples include the Intel® Xeon® FC-mPGA package, the HP mx2 dual-processor module, and
the IBM Power 5 MCM.
Profile Viewer Provides a visual display of historical utilization data collected by Capacity Advisor, along with
additional information that you have provided. The Profile Viewer enables you to examine different
time intervals and different categories of data.
provision A function that makes a component operational. Provisioning might include installing, upgrading,
loading, and configuring a software or hardware component. Provisioning a server includes
loading the appropriate software (operating system and applications), customizing and configuring
the system, and starting the server and its newly-loaded software. This makes the system ready
for operation.
Quality of Service A combination of qualitative and quantitative factors such as up time, response time, and available
bandwidth, that collectively to describe how well a system performs. The Quality of Service is
frequently embodied in a Service Level Agreement or in a set of Service Level Objectives between
or among organizations.
relative headroom The percentage by which the demand on a resource can grow before the utilization limits set for
the resource are exceeded.
See also headroom.
resource partition A subset of the resources available to an operating system instance, isolated for use by specific
processes. A resource partition has its own process scheduler.
scenario A possible configuration of systems and workloads under consideration when doing capacity
planning.
See also what-if scenario.
