HP Capacity Advisor 7.2 User Guide

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 Capacity Advisor, 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.

virtual machine
management
Insight Control virtual machine management. The HP Matrix Operating Environment application
that allows you to manage and configure Integrity VM.
virtual partition A software partition of a server, or of a single nPartition, where each virtual partition can run its
own instance of an operating system. A virtual partition cannot span an nPartition boundary.
See also nPartition, virtual machine.
visualization Provides hierarchical visualization of servers and workloads, with seamless access to the
management tools of the Matrix OE technologies.
VM See virtual machine.
VM Host A server running HP Integrity Virtual Machines, VMware ESX, VMware ESXi, or Microsoft Hyper-V,
that provides multiple virtual machines, each running its own instance of an operating system.
vPars An HP software product that provides virtual partitions.
See also virtual machine.
vPars monitor The program that manages the assignment of resources to virtual partitions in a vPars-enabled
system. To enable virtual partitions, the vPars monitor must be booted in place of a normal HP-UX
kernel. Each virtual partition running under the monitor then boots its own HP-UX kernel.
The vPars monitor reads and updates the vPars partition database, boots virtual partitions and
their kernels, and emulates certain firmware calls.
See also VM Host.
WBEM Web-Based Enterprise Management. A set of web-based information services standards developed
by the Distributed Management Task Force, Inc. A WBEM provider offers access to a resource.
WBEM clients send requests to providers to get information about and access to the registered
resources.
See also Utilization Provider.
