HP Cluster Test Software manual Glossary, Cmu

Glossary

administration disk	The disk located on the image server on which HP Insight CMU is installed. A dedicated space
	can be allocated to the cloned images.
administration	The private network within the system that is used for administrative operations.
network
clone image	The compressed image of the installation from the master disk. One clone image is needed for
	each logical group.
cluster	A set of independent computers combined into a unified system through system software and
	networking technologies.
CMU	HP Insight Cluster Management Utility
compute node	A node that is assigned only with the compute role and no other. Jobs are distributed to and run
	on nodes with the compute role. No other services run on a compute node.
control node	Another word for the head node.
head node	The node on which HP Cluster Test is installed on and run. Typically, the head node is also the
	image server. More than one head node can exist in a cluster.
iLO	Integrated Lights Out. A self-contained hardware technology that enables remote management
	of any node within a system.
iLO 2	The next generation of iLO that provides full remote graphics console access and remote virtual
	media.
image server	A node specifically designated to hold images that will be distributed to the nodes dedicated as
	secondary servers in each network entity. In a standard HP Insight CMU installation, the head
	node acts as the image server.
logical group	A group of similar machines running the same image. A node can belong to several logical
	groups.
management card	A hardware device on a server that enhances remote manageability. The management cards
	supported by HP Insight CMU are iLO, iLO 2, and LO 100i.
management	Typically, a private, Ethernet-based LAN that connects all the nodes in a cluster. HP Insight CMU
network	communicates with the compute nodes and terminal servers over the management network.
management node	Another term for head node.
master disk	A reference disk where the operating system and layered products are manually installed. Its
	contents are duplicated on the other nodes of a group.
network entity	A group of machines that are connected with an Ethernet switch. In each network entity, one of
	the nodes is temporarily dedicated as the secondary server, which means that it has the same
	role as the image server. Each node belongs to a unique network entity.
OA	Onboard Administrator. The enclosure management hardware, software, and firmware that is
	used to support all managed devices contained within the enclosure.
PXE	Preboot Execution Environment. A standard client/server interface that enables uninstalled network
	computers with an operating system to be configured and booted remotely. PXE booting is
	configured at the BIOS level.
RPM	Red Hat Package Manager.
	1.	A utility that is used for software package management on Linux operating systems, most
		notably to install and remove software packages.
	2.	A software package that is capable of being installed or removed with the RPM software
		package management.
secondary server	A dedicated node in a network entity where the cloned image is temporarily stored. The cloned
	image is propagated only to the other nodes that are defined inside the entity.
target disk	The hard drive on a target node where the cloned image is installed.
target node	A compute node that will receive the cloned image from a secondary server.
