Serviceguard
package

Packages are the means by which Serviceguard starts and halts configured applications. A
package is a collection of services, disk volumes and IP addresses that are managed by
Serviceguard to ensure they are available.

Serviceguard
workload

A

monitored workload

associated with a

Serviceguard cluster

and a particular

package

within the

cluster. The workload (and the utilization data reported) follows the package it is associated
with as it moves between the nodes of the cluster.

simulation

A mock situation (scenario) that allows you to experiment with various capacity-planning
solutions.

SMH

See HP SMH.

standalone server

Hardware that can run one or more operating systems but does not support dividing hardware
resources into

nPartitions

.

system

A

server

,

nPartition

,

virtual partition

, or

virtual machine

that is running an instance of an

operating system.

1.

2.

Entities on the network that communicate through TCP/IP or IPX. To manage a system,
some type of management protocol (for example, SNMP, DMI, or

WBEM

) must be present

on the system. Examples of systems include

servers

, workstations, desktops, portables,

routers, switches, hubs, and gateways.

See also server.

system headroom

See headroom.

unbound core

For

vPars

versions prior to A.04xx, an unbound core is one that can be migrated between

virtual

partitions

while those partitions are running. Unbound cores cannot handle I/O interrupts.

Unbound cores are sometimes referred to as “floater processors.”

The distinction between bound and unbound cores does not apply to vPars version 4.0 or later.

utilization limits

The limits set on the usage of system resources such as CPU, memory, or network I/O by an
application. Utilization limits are expressed as a percent of the system capacity and the amount
of time an application is allowed to exceed this limit. The time that a limit is exceeded can be
expressed as a percentage of time or as a maximum duration of time.
See also max 15-min.

Utilization
Provider

The

WBEM

services provider for real-time utilization data from

managed systems

.

valid data

In

HP Insight Capacity Advisor software

, data that meaningfully contributes to the user's ability

to understand actual past resource usage and that provides reliable information for accurately
forecasting current and future capacity needs.
See also invalid data, missing data.

VC

HP Virtual Connect. A set of interconnect modules and embedded software for HP BladeSystem
c-Class enclosures that simplifies the setup and administration of server connections, thereby
enabling administrators to add, replace, and recover server resources dynamically.

vCPU

Virtual CPU. A single-core virtual processor in a

virtual machine

.

See also core, processor.

virtual device

An emulation of a physical device. This emulation, used as a device by an

Integrity VM virtual

machine

, effectively maps a virtual device to an entity (for example, backing store) on the

VM

Host

.

virtual machine

A software entity provided by HP Integrity Virtual Machines, VMware ESX, VMware ESXi, or
Microsoft Hyper-V. This technology allows a single

server

or (with Integrity Virtual machines)

nPartition

to act as a

VM Host

for multiple individual virtual machines, each running its own

instance of an operating system (referred to as a

guest OS

). Virtual machines are managed

systems in the HP Virtual Server Environment (VSE).
