host
The
, which is the controlling operating system that allows multiple
(VMs) to be booted on a single server or nPartition.
1.
2.
A system or partition that is running an instance of an operating system.
Integrity VM
HP Integrity Virtual Machines. The HP product that allows you to install and run multiple
systems (
) on the same physical
system.
legacy addressing
The storage device addressing model that uses the device special file (DSF) path as defined in
HP-UX 11i v2 and earlier versions. In contrast to the
model introduced with
HP-UX 11i v3, the legacy device special file (DSF) is bound to a specific hardware path to a
storage device. For this reason, a device with multiple paths is represented by several legacy
DSFs. If the physical storage device is reconnected to a
through a different host bus adapter
(HBA) or a different target port, the address represented by the DSF is affected, requiring
reconfiguration of applications, volume managers, or file systems. Likewise, if additional paths
are offered to a given LUN (through the addition of a new SCSI controller or new SCSI target
paths), an equal number of additional DSFs are required to address them.

localnet
A
created by default when
is installed on a
. The local network
created by this vswitch can be used for communications among
but not for communication
between the VM Host and any guest or between any external system and a VM guest.
managed node
A system running under HP SIM/Insight Dynamics. Systems become managed nodes through
the HP SIM discovery mechanism.
managed system
See managed node.
MSE group
Multiserver Environment group. A set of
servers can be grouped into an Integrity
VM MSE group, as required when a set of Integrity VM servers is also configured as a
cluster.
NIC
Network interface card. Also called LAN card, LAN adapter, or PPA.
nPartition
A partition in a cell-based server that consists of one or more cells, and one or more I/O chassis.
Each nPartition operates independently of other nPartitions and either runs a single instance
of an operating system or is further divided into virtual partitions.
nPartitions can be used as compartments managed by HP Insight Global Workload Manager
software for Integrity (gWLM) as long as several requirements are met. Refer to the gWLM
online help for a description of nPartition requirements.
processor
Also referred to as the central processor unit (CPU), a processor is the hardware component in
a computer that processes instructions and plugs into a processor socket. A processor can
contain more than one
.
See also core.
Serviceguard
HP Serviceguard. A product that allows you to create high-availability
of HP 9000 or
HP Integrity servers. By installing Serviceguard on an HP Integrity VM Host system,
Serviceguard can manage
as Serviceguard packages. A Serviceguard
package groups application services (individual HP-UX processes) together and maintains
them on multiple nodes in the cluster, making them available for failover. When the VM Host
system fails, the guests automatically fail over to another node in the Integrity VM multiserver
environment (
). By installing Serviceguard on HP Integrity guests, each guest becomes
a Serviceguard cluster node. When a virtual machine fails, the guest applications can fail over
to another guest configured as a Serviceguard node or to another server or partition.
shared vswitch
A
that can be used by more than one active
Utilization
Provider
The
services provider for real-time utilization data from
vCPU
Virtual CPU. A single-core virtual processor in a
.
See also core, processor.
virtual CPU
See vCPU.
virtual machine
A software entity provided by HP
. This technology allows a single
server or
to act as a
for multiple individual virtual machines, each running
its own instance of an operating system (referred to as a
). Virtual machines are managed
