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 system

A server or other

system

that can be managed by HP SIM from a

CMS

. A managed system can

be managed by more than one CMS.

managed
workload

A

workload

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

(gWLM).

management
domain

A

CMS

and its

managed systems

.

monitored
workload

A

workload

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

policy

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

Manager software for Integrity (gWLM).

MSA

HP StorageWorks Modular Smart Array. MSA is a direct attach, external shared storage solution
that helps customers easily transition from direct attached to centralized storage. It allows
departmental and small- to medium- business customers to grow capacity as demands increase.

nPartition

A

partition

in a

cell-based server

that consists of one or more

cells

and one or more I/O components.

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.

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

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.

1.

2.

A

resource partition

, made up of either a

Fair-Share Scheduler (FSS) group

or a

processor set

,

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

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.

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.

PSET

Processor set. A collection of processors grouped together for exclusive access by applications
assigned to that processor set. Each application runs only on processors in its assigned processor
set.

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. CPU resources in the partition
may be allocated using

Fair-Share Scheduler groups

or

processor sets

. Policies for controlling the
