Concepts and Terminology

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

The process of finding applications and gathering performance data about them for display and use in a managed environment.

Two or more systems configured together to host workloads, in a way that users are unaware that more than one system is hosting the workload. A Serviceguard cluster is a specific type of cluster managed by Serviceguard software.

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

A graphical representation of systems and workloads by the Virtualization Manager software. From the Visualization tab, a hierarchical view presents systems (such as an nPartition, virtual partition, virtual machine, virtual connect domain, and so on) and their children as a self-contained unit. You can select the entire compartment or individual members within a compartment, then use the Virtualization Manager drop-down menu items and toolbar.

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

A CMS and its managed systems.

A hardware partition in a complex. Each nPartition operates independently of other nPartitions and either runs a single instance of an operating system or is further divided into virtual partitions. An nPartition can be used as a compartment managed by gWLM.

A collection of rules and settings that control workload resources. For example, a policy can indicate the minimum and maximum amount of processor resources allowed for a workload and a target to be achieved. A single policy can be associated with multiple workloads.

Shared resource domain. A collection of compartments that share system resources. The compartments can be nPartitions, virtual partitions, virtual machines, psets, or FSS groups.

HP Virtual Connect; a set of interconnect modules and embedded software for HP BladeSystem c-Class enclosures that simplifies the setup and administration of server connections, thereby enabling administrators to add, replace, and recover server resources dynamically.

A logical grouping of servers, visible by expanding a VC domain compartment from the Virtualization Manager's Visualization View, Blades perspective. Currently, only HP BladeSystem c-Class servers appear in a VC domain. VC domains can be collected in a group, and similiarly expanded from the Virtualization Manager.

A logical collection of VC domains with the same network and storage configuration. A VC domain group can be expanded from the Virtualization Manager's Visualization View, Blades perspective.

A software entity provided by HP Integrity Virtual Machines, VMware ESX, or Microsoft Virtual Server. 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, provided by HP vPars. Each virtual partition can run its own instance of an operating system. A virtual partition cannot span an nPartition boundary.

The view presented by clicking the Virtualization Manager's Visualization tab. By default, the view “perspective” is set for physical and logical systems. Alternately, you can change the view to show logical servers, server blades, virtual machines, Serviceguard, or systems and events.

A basic unit of manageability in Virtualization Manager. A workload is a set of processes whose real-time resource utilization can be monitored by Virtualization Manager and collected by Capacity Advisor. Workloads assigned to a Shared Resource Domain (SRD) can be managed according to a policy by Global Workload Manager (gWLM). Workloads are graphically displayed from the Virtualization Manager's Visualization View and Workload view. Workload types include: managed workloads that are managed by Global Workload Manager (gWLM) and monitored workloads that are not managed by gWLM and do not have a policy associated with them but can be monitored by Virtualization Manager. Whole-OS workloads include a set of all processes running on a system (server, nPartition, virtual partition, or virtual machine). Whole-OS workloads are not displayed as workloads in the Visualization View but are represented by the compartment box for the system. Serviceguard workloads are monitored workloads associated with a Serviceguard cluster and a particular package within the cluster.
