Glossary

A

 

administration

The half (branch) of the administration network that contains all of the general-purpose

branchadministration 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 HostSee 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.

external networkA node that is connected to a network external to the HP XC system.

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.
