HP-UX System Administrator's Guide: Overview

Utility Meter The software and hardware device that receives PPU utilization information from the PPU
software. The utility meter is initially installed and configured by an HP service representative.
virtual LUN
ID
The final element in a LUN hardware path (0x3 in the following example):
64000/0xfa00/0x3
virtual
machine
Abstractions of real, physical machines. Multiple virtual machines can share a common set of
physical resources.
See also Integrity VM guest.
Virtual
Partition
A software partitioning of a server or nPartition where each virtual partition contains an instance
of an operating system. Though an nPartition can contain multiple virtual partitions, the inverse
is not true — a virtual partition cannot span nPartition boundaries.
See also nPartitions.
virtual root
node
In a virtualized path to a device (in the agile view), instead of a series of bus-nexus addresses
leading to the HBA, the path contains a virtual bus-nexus (with an address of 64000). This virtual
bus-nexus is called the “virtual root node”. An example of a LUN hardware path (showing the
virtual root node) is:
64000/0xfa00/0x3
Virtual Server
Environment
(VSE)
An integrated server virtualization offering for HP-UX, Linux, and Windows servers that provides
a flexible computing environment maximizing usage of server resources.
VSE consists of a pool of dynamically sizeable virtual servers; each can grow and shrink based
on service level objectives and business priorities. For more information, see http://hp.com/go/
vse.
See also Service Level Objective.
virtualization
Technologies for using your computing resources in ways not dependent on the physical
characteristics of those resources. For example, a logical volume can span multiple physical disk
devices.
virtualized
LUN
hardware path
See LUN hardware path.
volume group A collection of physical volumes (physical disks), used by the Logical Volume Manager. Volume
groups can be subdivided into logical volumes (flexible virtual disks that can contain file systems,
swap space, or used as dump devices or raw disk access).
See also logical volume.
vPars See Virtual Partitions.
WBEM
(Web-Based
Enterprise
Management)
WBEM is a set of management and Internet standard technologies developed by the Distributed
Management Task Force (DMTF) to unify the management of enterprise computing environments.
