HP Insight Capacity Advisor 6.0 Software: User Guide

management
domain
A CMS and its managed systems.
max 15-min Maximum 15-minute sustained: data given in the Utilization Metric Summary screen of the HP
Insight Capacity Advisor software Profile Viewer, the highest value in the selected time interval
that was sustained for at least 15 minutes.
metric A specific measurement that defines a performance characteristic.
metric view
selection
In HP Insight Capacity Advisor software, a combination of the statistical model (such as peak or
average) used to calculate the metric and whether it is to be presented as a percentage or an
absolute value.
missing data Data that was not collected by HP Insight Capacity Advisor software, perhaps because a monitored
system was down during data collection. Such data is not used in analysis, though the collection
gap may be shown in the Profile Viewer.
See also invalid data, valid data.
monitored
workload
A workload that can be monitored by HP Insight Virtualization Manager software on HP-UX and
OpenVMS managed nodes, but which has no policy associated with it. Monitored workloads
are not managed by HP Insight Global Workload Manager software for Integrity (gWLM).
multithreading The ability of an application and operating system to allow parallel computing by dividing
processing between multiple processors or cores.
node See system.
nPartition A partition in a cell-based server that consists of one or more cells , and one or more I/O chassis.
Each nPartition operates independently of other nPartitions and either runs a single instance
of an operating system or is further divided into virtual partitions.
See also virtual partition.
OS Operating system.
package A package groups application services (individual HP-UX processes) together.
See also Serviceguard package.
parked workload A workload that is not currently associated with a system. A workload becomes parked if its
system is set to “none” when it is created or later modified. A parked workload that was
previously associated with a system may have historical data associated with it from HP Insight
Capacity Advisor software or HP Insight Global Workload Manager software for Integrity (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 HP Insight Global
Workload Manager software for Integrity (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.
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.
