Glossary

A logically related set of processes active on a host system (a running application ) and/or a logically related set of files on a host system disk (an installed application).

HP Application Discovery recognizes applications based on standard package installation, templates that are shipped with the product, and templates that are defined by users.

The process of finding applications and gathering performance and location data about them for display and use.

A set of two or more systems configured together to host workloads, such that users are unaware that more than one system is hosting the workload.

Central management server. A system in the management domain that executes the HP Systems Insight Manager (HP SIM) software. All central operations within HP SIM are initiated from this system.

An nPartition, virtual partition, virtual machine, or resource partition whose resources are allocated by HP Global Workload Manager (gWLM).

Multiple compartments are grouped to form a shared resource domain (SRD). The compartments all share the resources of the SRD. A compartment can be in only one SRD. Each compartment holds a workload. gWLM manages each workload's resource allocation by adjusting the resource allocation of its compartment.

One or more hardware cabinets that are cabled together and that contain cells (circuit boards containing processors and memory), each of which can be assigned for exclusive use by an nPartition.

A set of resource-demand readings made at regular intervals for some period of time. The demand profile of a workload, system, or complex is used when doing capacity planning. Demand profiles can be based on historical data or computed as part of a forecast.

HP Global Instant Capacity. Software that enables you to move Rights To Use (RTUs) for Instant Capacity components within a group of servers. The GiCAP Group Manager page can be launched from an icon on the HP Virtualization Manager's Virtualization view.

HP Instant Capacity. The HP Utility Pricing Solutions product whose pricing model is based on purchasing components (processors, cell boards, and memory). With Instant Capacity you initially purchase a specified number of activated components and pay a right-to-access fee for a specified number of deactivated (iCAP) components. To activate a component, you purchase the component and license it through the application of a codeword.

Previous versions of iCAP were referred to as Instant Capacity on Demand, or iCOD.

A feature provided by HP Virtualization Manager, 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.

A server or other system that can be managed by HP SIM from a CMS.

A workload that is managed by HP Global Workload Manager (gWLM).

A CMS and its managed systems.

A workload that can be monitored by HP Virtualization Manager but has no policy associated with it. Monitored workloads are not managed by gWLM.

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 Global Workload Manager (gWLM) as long as several requirements are met. See the gWLM online help for a description of nPartition requirements.

A collection of rules and settings that control workload resources managed by HP Global Workload Manager (gWLM). For example, a policy can indicate the minimum and maximum amount of CPU resources allowed for a workload, and a target to be achieved.

A single policy can be associated with multiple workloads.

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 (gWLM).

A resource partition that is integrated with HP-UX Security Containment.

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. These requirements are detailed in the gWLM Getting the Most out of gWLM topic in the gWLM online help.

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.

An HP-supplied or user-defined set of rules, properties, or metadata that describe an object in a computing network.

Temporary Instant Capacity. An HP product that enables customers to purchase prepaid processor activation rights, for a specified (temporary) period of time. Temporary capacity is sold in 30-processor-day increments. TiCAP was formerly referred to as “TiCOD”.

A software entity provided by HP Integrity Virtual Machines, VMware ESX, or Microsoft Virtual Server. This technology allows a single server or (in the case of Integrity Virtual Machines) nPartition to act as a VM Host for multiple individual virtual machines, each running its own instance of an operating system (referred to as a guest OS). Virtual machines are managed systems in the HP Virtual Server Environment (VSE).

A software partition of a server, or of a single nPartition, where each virtual partition can run its own instance of an operating system. A virtual partition cannot span an nPartition boundary.

The collection of processes in a standalone server, nPartition compartment, virtual partition compartment, or virtual machine compartment. HP Global Workload Manager (gWLM) extends this concept to include processor set (PSET) compartments and Fair-Share Scheduler (FSS) group compartments. gWLM enables you to monitor and manage workloads by automatically adjusting the resource allocations of compartments based on policies.
