HP Insight Capacity Advisor 6.0 Software: User Guide

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.

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).
