operating system and its loader. Together, these provide a standard environment for booting

 

an operating system and running preboot applications.

enclosure

The hardware and software infrastructure that houses HP BladeSystem servers.

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.

FCFS

First-come, first-served. An LSF job-scheduling policy that specifies that jobs are dispatched

 

according to their order in a queue, which is determined by job priority, not by order of

 

submission to the queue.

first-come,

See FCFS.

first-served

 

G

 

global storage

Storage within the HP XC system that is available to all of the nodes in the system. Also known

 

as local storage.

golden client

The node from which a standard file system image is created. The golden image is distributed

 

by the image server. In a standard HP XC installation, the head node acts as the image server

 

and golden client.

golden image

A collection of files, created from the golden client file system that are distributed to one or

 

more client systems. Specific files on the golden client may be excluded from the golden image

 

if they are not appropriate for replication.

golden master

The collection of directories and files that represents all of the software and configuration data

 

of an HP XC system. The software for any and all nodes of an HP XC system can be produced

 

solely by the use of this collection of directories and files.

H

 

head node

The single node that is the basis for software installation, system configuration, and

 

administrative functions in an HP XC system. There may be another node that can provide a

 

failover function for the head node, but HP XC system has only one head node at any one time.

host name

The name given to a computer. Lowercase and uppercase letters (a–z and A–Z), numbers (0–9),

 

periods, and dashes are permitted in host names. Valid host names contain from 2 to 63

 

characters, with the first character being a letter.

I

 

I/O node

A node that has more storage available than the majority of server nodes in an HP XC system.

 

This storage is frequently externally connected storage, for example, SAN attached storage.

 

When configured properly, an I/O server node makes the additional storage available as global

 

storage within the HP XC system.

iLO

Integrated Lights Out. A self-contained hardware technology available on CP3000 and CP4000

 

cluster platform hardware models that enables remote management of any node within a

 

system.

iLO2

The next generation of iLO that provides full remote graphics console access and remote virtual

 

media.
