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.

A complex includes one or more cabinets that are cabled together and all of the hardware resources that they contain. A complex has a single Service Processor.

The actual data-processing engine within a processor. A single processor might have multiple cores, and a core might support multiple execution threads.

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.

Fair-Share Scheduler group. A group of processes that has its CPU allocation managed by the HP-UX FSS. FSS groups allow you to allocate fractions of cores, rather than only whole cores, to the processes in the group.

HP Global Instant Capacity. Software that enables you to move usage rights 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 Visualization view.

Microsoft Hyper-V (formerly Microsoft Server Virtualization). A hypervisor-based virtualization system that allows multiple operating systems to run on a host at the same time. Hyper-V supports partitions in which the operating systems run, including one parent partition running Windows Server 2008.

HP Instant Capacity. The HP Utility Pricing Solutions product that 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.

Earlier 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 Systems Insight Manager (HP SIM) from a CMS . A managed system can be managed by more than one 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 HP Global Workload Manager (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. Refer to 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.

Processor set. A collection of processors grouped together for exclusive access by applications assigned to that processor set. Each application runs only on processors in its assigned processor set.

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.

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.

In HP Application Discovery, templates specify the data collection and matching rules to be used to define and discover an application.

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. TiCAP was formerly known as “TiCOD”.

The WBEM services provider for real-time utilization data from managed systems.

A software entity provided by HP Integrity Virtual Machines, VMware ESX, Microsoft Virtual Server, or Microsoft Hyper-V. This technology allows a single server or (with 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.

A server running software such as HP Integrity Virtual Machines, VMware ESX, Microsoft Virtual Server, or Microsoft Hyper-V, that provides multiple virtual machines, each running its own instance of an operating system.

Web-Based Enterprise Management. A set of web-based information services standards developed by the Distributed Management Task Force, Inc. A WBEM provider offers access to a resource. WBEM clients send requests to providers to get information about and access to the registered resources.

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.
