HP Matrix Operating Environment 7.1 Getting Started Guide

iCAP HP Instant Capacity. The product allows you to purchase and install additional processing power
through the use of a two-step purchase model. Initially, you purchase system components (cores,
cell boards, memory) at a fraction of the regular price because the usage rights are not included.
These Instant Capacity components are inactive but installed and ready for use. When extra
capacity is needed, you pay the remainder of the regular price for the usage rights to activate
the components. If the regular price for the component is reduced by the time the usage rights
are purchased, the remainder price is proportionally reduced, providing additional savings.

logical server A logical server is the complete software image of a server, including operating system,
applications, configuration data, and metadata that you create and assign to operate on a
physical server or virtual machine. Logical servers simplify the provisioning, management, and
movement of servers; and they allow you to quickly populate an enclosure, load balance servers,
and evacuate servers in case of disaster. Using logical servers, you can provision resources only
when needed, increasing optimal utilization of limited compute resources. Logical servers are a
feature of the HP Matrix Operating Environment.

LTU License to use.
managed instance A resource that is managed via a public cloud service provider. These resources are represented
as Cloud Resources inside HP CloudSystem Matrix and can be added to a server pool in the
same way as any other VM Host or ESX Resource Pool.
managed system A server or other system that can be managed and monitored by HP Insight Management software
from an HP Systems Insight Manager CMS. A system can be managed and monitored by more
than one CMS.
managed
workload
A workload that is managed by HP Global Workload Manager.
management
domain
A CMS and its managed systems.
monitored
workload
A workload that can be monitored by the HP Matrix Operating Environment, but has no policy
associated with it. Monitored workloads are not managed by HP Global Workload Manager.
nPartition A partition in a cell-based server that consists of one or more cells and one or more I/O
components. 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 Global Workload Manager (gWLM)
as long as several requirements are met. Refer to the gWLM online help for a description of
nPartition requirements.
See also virtual partition.
parked workload A workload that is not currently associated with a system. A workload becomes parked if its
system is set to “none” when it is created or later modified. A parked workload that was previously
associated with a system may have historical data associated with it from Capacity Advisor or
HP Global Workload Manager. As with any workload, the historical data is lost if the workload
is deleted.
When migrating a workload from one system to another, it may be useful to park the workload
(removing the association with the original system) until the new system becomes available. This
preserves the historical data for the workload across the migration.
partition A subset of server hardware that includes core, memory, and I/O resources on which an
operating system (OS) can be run. This type of partitioning allows a single server to run an
OS independently in each partition with isolation from other partitions.
1.
2. A resource partition, made up of either a Fair-Share Scheduler (FSS) group or a processor
set, that runs within a single OS. This type of partitioning controls resource allocations within
an OS.
See also nPartition, virtual partition.
policy A collection of rules and settings that control compute resources For example, an HP Global
Workload Manager (gWLM) policy can indicate the minimum and maximum amount of CPU
resources allowed for a workload, and a target to be achieved.
