HP-UX vPars and Integrity VM V6.3 Administrator Guide

Glossary
This glossary defines the terms and abbreviations as they are used in the Integrity VM
product documentation.
Accelerated Virtual
Input/Output
See AVIO
adoptive node The cluster member where the package starts after it fails over.
APA Auto Port Aggregation. An HP-UX software product that creates link aggregates, often called
“trunks,” which provide a logical grouping of two or more physical ports into a single “fat pipe”.
This port arrangement provides more data bandwidth and higher reliability than would otherwise
be available.
application A collection of processes that perform a specific function. In the context of virtual machine clusters,
an application is any software running on the guest.
assignable
resource
The resources that you can designate to be assigned to a partition.
asymmetric
Serviceguard
configuration
A cluster configuration in which the cluster nodes do not have access to the same physical storage
and network devices.
autoboot A characteristic of a virtual machine whereby it is set to start whenever Integrity VM starts. Virtual
machines can be set to either auto or manual boot using the -B option to the hpvmcreate,
hpvmmodify, hpvmmigrate, or hpvmclone commands.
available resources Processors, memory, and I/O resources that are not assigned to a virtual machine. These resources
are available to be used in new partitions or can be added to existing partitions.
AVIO Accelerated Virtual Input/Output. An I/O protocol that improves virtual I/O performance for
network and storage devices used within the Integrity VM environment. The protocol also enables
support for a greater number of virtual I/O devices per guest. Special drivers are required on
both the VSP and guests. Participating guests must include a virtual I/O device configured to use
the AVIO protocol.
backing store The physical device on the VSP that is allocated to guests, such as a disk or file.
Base memory This can be used by vPar kernel for critical data structures. You can add the memory but cannot
delete from a live vPar.
Blade A board that contains CPUs and memory, and slots for C-class mezzanine cards, and onboard
NICs. A blade is the equivalent of a cell in terms of being the unit of assignment for defining
nPartitions.
BMC Baseboard Management Controller. The Management Processor (MP) console for Intel® Itanium
systems.
boot virtual
machines
To load a virtual machine's operating system and start it. Once a virtual machine has been
configured with an operating system, it is considered a guest, and is started automatically when
Integrity VM starts, or manually using the hpvmstart command.
See also start virtual machines.
c3000 enclosure The HP BladeSystem c3000 enclosure works well in smaller data centers. A single c3000 enclosure
is 6U high and can hold up to eight server, storage, or I/O option blades and up to four
interconnect modules.
c7000 enclosure The HP BladeSystem c7000 enclosure is optimized for enterprise data centers. A single c7000
enclosure is 10U high and can hold up to 16 server, storage, or I/O option blades and up to
eight interconnect modules.
captive virtual
console account
A special-purpose user account created on the VSP for each guest administrator or operator.
cell local memory See CLM
CLM Non-interleaved memory that can be quickly accessed by processors residing on the same socket
as the memory. This is the same concept as SLM.
