invalid data In Capacity Advisor , data that could potentially skew reporting results and lead to inaccurate or
misleading conclusions when capacity planning. Examples of events that Capacity Advisor can
recognize as potential sources of invalid points include the following:
•
System downtime during a data collection period
•
Data manually marked by the user as invalid
•
Partial collection from a virtual machine or a VM host
See also missing data, valid data.
Itanium®-based
systems Systems built on any version of the Intel® Itanium® architecture.
logical server A feature provided by Matrix OE visualization, a logical server is a set of configuration and
metadata that you create, activate, and assign to operate within a physical or
virtual machine .
An active logical server can be moved from one location to another, and its characteristics can
be modified. This feature allows you to populate an enclosure, load balance servers, and evacuate
servers in case of disaster; it allows you to
provision resources only when needed and increase
utilization of limited compute resources.
See also active logical server, inactive logical server.
LTU License to use. One of the three main components of Global Workload Manager (gWLM) : CMS ,
agents, and LTU for each agent. The CMS allows you to control and monitor gWLM. The agents
run on the systems where you are managing workloads. You install an LTU on each system that
runs an agent in order to continue full agent functionality beyond the initial trial period.
managed resource A resource that can be allocated and controlled using the Matrix OE visualization interface.
Managed resources include:
cores , memory, disks, and I/O bandwidth.
managed system A server or other system that can be managed by Systems Insight Manager from a CMS . A
managed system can be managed by more than one CMS.
managed
workload A workload that is managed by Global Workload Manager (gWLM) .
management
domain A CMS and its managed systems .
max 15-min Maximum 15-minute sustained: data given in the Utilization Metric Summary screen of the Capacity
Advisor Profile Viewer , the highest value in the selected time interval that was sustained for at
least 15 minutes.
metric A specific measurement that defines a performance characteristic.
metric view
selection In Capacity Advisor , a combination of the statistical model (such as peak or average) used to
calculate the metric and whether it is to be presented as a percentage or an absolute value.
missing data Data that was not collected by Capacity Advisor , perhaps because a monitored system was down
during data collection. Such data is not used in analysis, though the collection gap may be shown
in the
Profile Viewer .
See also invalid data, valid data.
monitored
workload A workload that can be monitored by Matrix OE visualization but has no policy associated with
it. Monitored workloads are not managed by Global Workload Manager (gWLM) .
multithreading The ability of an application and operating system to allow parallel computing by dividing
processing between multiple
processors or cores .
node See system.
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 .
See also virtual partition.
OS Operating system.
package A package groups application services (individual HP-UX processes) together.
See also Serviceguard package.
