HP Matrix Operating Environment 7.0 Getting Started Guide

resource partition A subset of the resources available to an operating system instance, isolated for use by specific
processes. A resource partition has its own process scheduler. CPU resources in the partition may
be allocated using Fair-Share Scheduler groups or processor sets. Policies for controlling the
allocation of resources to the partition can be set using HP Global Workload Manager.
server blades Thin, modular, self-contained computer servers, containing one or more microprocessors and
memory. Server blades are designed for high density and eliminate many components such as
power cords and network cables that are present in traditional rack-mount systems.
service processor An independent support processor for HP servers that support nPartitions. The service processor
provides a menu of service-level commands, plus commands to reset and reboot nPartitions and
configure various parameters.
The service processor in HP servers is sometimes called the management processor (MP) or the
guardian service processor (GSP).
Serviceguard
cluster
An HP Serviceguard cluster is a networked group of HP 9000 or HP Integrity servers (host systems
known as nodes) having sufficient redundancy of software and hardware that a single point of
failure will not significantly disrupt service.
Serviceguard
package
Packages are the means by which HP 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.
SMI-S Storage Management Initiative Specification. SMI-S delivers open storage network management
interface technology in order to have “all storage managed by the SMI interface” as the unifying
factor between all objects that must be managed in a storage area network and the tools used
to manage them.
socket (CPU socket). The physical chip carrier on the circuit board that houses a CPU chip. The CPU
may consist of multiple cores.
SRD Shared resource domain. A collection of compartments that share system resources managed by
HP Global Workload Manager (gWLM). The compartments can be nPartitions, virtual partitions,
virtual machines, processor sets (PSETs) or Fair-Share Scheduler (FSS) groups.
A server containing nPartitions can be an SRD as long as nPartition requirements are met.
A server or an nPartition divided into virtual partitions can be an SRD for its virtual partition
compartments. A VM Host can be an SRD to its virtual machines. Similarly, a server, an nPartition,
or a virtual partition containing PSETs can be an SRD for its PSET compartments. Finally, a server,
an nPartition, or a virtual partition containing FSS groups can be an SRD for its FSS-group
compartments.
A complex with nPartitions can hold multiple SRDs. For example, if the complex is divided into
nPartitions named Par1 and Par2, Par1's compartments could be virtual partitions, while Par2's
compartments are PSETs.
SSL Secure Sockets Layer. Protocol for validating identity and for creating an encrypted connection
between a server and a Web browser.
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.
TiCAP Temporary Instant Capacity. An HP product that enables customers to purchase prepaid core
activation rights for a specified (temporary) period of time. Temporary capacity is sold in 30
processing-day increments.
Utilization Provider The WBEM services provider for real-time utilization data from managed systems.
VCEM Virtual Connect Enterprise Manager. A management tool for defining a server connection profile
for each server bay. This profile establishes the media access control (MAC) addresses for all
