Integrity VM

HP Integrity Virtual Machines. 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.

logical server

A feature provided by HP Insight Virtualization Manager software, a logical server is a set of

 

configuration and metadata that you create, activate, and assign to operate within a physical

 

or virtual machine. An active logical server can be moved from one location to another, and its

 

characteristics can be modified. This feature allows you to populate an enclosure, load balance

 

servers, and evacuate servers in case of disaster; it allows you to provision resources only when

 

needed and increase utilization of limited compute resources.

managed

A workload that is managed by HP Insight Global Workload Manager software for Integrity

workload

(gWLM).

monitored

A workload that can be monitored by HP Insight Virtualization Manager software but has no policy

workload

associated with it. Monitored workloads are not managed by HP Insight Global Workload

 

Manager software for Integrity (gWLM).

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.

 

nPartitions can be used as compartments managed by HP Insight Global Workload Manager

 

software for Integrity (gWLM) as long as several requirements are met. Refer to the gWLM

 

online help for a description of nPartition requirements.

 

See also virtual partition.

package

A package groups application services (individual HP-UX processes) together.

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 Capacity

 

Advisor 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.

 

2. A resource partition, made up of either a Fair-Share Scheduler or a processor set, that runs

 

within a single OS. This type of partitioning controls resource allocations within an OS.

 

See also nPartition, virtual partition.

percent resident

A measure of the fractional amount of physical memory in use by a particular application for

memory

a period of time.

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.

process map

A script residing in /etc/opt/vse/scripts that enables you to create output process IDs

 

(PIDs).

processor set

See PSET.

pruned

When a file is reduced to a set number of lines based on criteria determined by the system

 

(application) or the software user.
