HP XC System 3.x Software manual Glossary

Glossary

A
administration	The half (branch) of the administration network that contains all of the general-purpose
branch	administration ports to the nodes of the HP XC system.
administration	The private network within the HP XC system that is used for administrative operations.
network
B
base image	The collection of files and directories that represents the common files and configuration data
	that are applied to all nodes in an HP XC system.
branch switch	A component of the Administration Network. A switch that is uplinked to the root switch and
	receives physical connections from multiple nodes.
C
cluster	A set of independent computers combined into a unified system through system software and
	networking technologies.
cluster alias	The external cluster host name supported by LVS, which enables inbound connections without
	having to know individual nodes names to connect and log in to the HP XC system.
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.
	.
Console Branch	A component of the administration network. The half (branch) of the administration network that
	contains all of the console ports of the nodes of the HP XC system. This branch is established as
	a separate branch to enable some level of partitioning of the administration network to support
	specific security needs.
D
DHCP	Dynamic Host Control Protocol. A protocol that dynamically allocates IP addresses to computers
	on a local area network.
Dynamic Host	See DHCP.
Control Protocol
E
EFI	Extensible Firmware Interface. Defines a model for the interface between operating systems and
	Itanium-based platform firmware. The interface consists of data tables that contain platform-related
	information, plus boot and run-time service calls that are available to the operating system and
	its loader. Together, these provide a standard environment for booting an operating system and
	running preboot applications.
extensible	See EFI.
firmware interface
external network	A node that is connected to a network external to the HP XC system.
node
F
fairshare	An LSF job-scheduling policy that specifies how resources should be shared by competing users.
	A fairshare policy defines the order in which LSF attempts to place jobs that are in a queue or a
	host partition.
