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

HP Insight Capacity Advisor

software

, along with additional information that you have provided. A 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.

For example, in the case of a system running several workloads, the relative headroom for any
one workload is the percentage by which one workload can grow without exceeding the
utilization limits set for itself and without causing any of the other workloads on the system to
exceed their limits.

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.

server

Physical server:

Hardware that can run one or more operating systems, including a

partitionable

complex

. Also, hardware that can run an instance of the

vPars monitor

. Server

1.

hardware includes one or more cabinets containing all the available processing

cores

,

memory, I/O, and power and cooling components. HP Integrity servers include two types
of server hardware: standalone servers and cell-based servers.

2.

Virtual server:

A software-based virtual environment that can run an operating system.

A virtual server includes a subset of the server hardware resources, including

cores

, memory,

and I/O. Virtual servers may be

virtual partitions

under

vPars

or

virtual machines

under

Integrity VM

.

3.

HP Systems Insight Manager software uses the term “server” for any standalone server,
nPartition, or virtual server that is running an instance of an operating system or an instance
of the vPars monitor.

See also system.

Service Processor

An independent support processor for HP servers that support

nPartitions

. The Service Processor

provides a menu of service-level commands, plus commands to reset and reboot nPartitions
and configure various parameters.

The Service Processor in HP servers is sometimes called the Management Processor (MP) or
the Guardian Service Processor (GSP).

Serviceguard

Specialized software for protecting mission-critical applications from a wide variety of hardware
and software failures. With Serviceguard, multiple servers (nodes) and/or server partitions are
organized into an enterprise cluster that delivers highly available application services to
LAN-attached clients. HP Serviceguard monitors the health of each node and rapidly responds
to failures in a way that minimizes or eliminates application downtime.

Serviceguard
cluster

A Serviceguard cluster is a networked grouping of HP 9000 or HP Integrity servers (host systems
known as nodes) having sufficient redundancy of software and hardware that a single point
of failure will not significantly disrupt service.
