HP XC System 2.x Software Image server, Integrated Lights Out, Interconnect, Internet address

image server

A node specifically designated to hold images that will be distributed to one or more client systems. In a standard XC installation, the head node acts as the image server and golden client.

Integrated Lights Out

See iLO

interconnect

The private network within the XC system that is used primarily for user file access and for communications within applications.

interconnect

Provides high-speed connectivity between the nodes. It is used for message passing and remote memory access capabilities for parallel applications.

Internet address

A unique 32-bit number that identifies a host’s connection to an Internet network. An Internet address is commonly represented as a network number and a host number and takes a form similar to the following: 192.168.0.1.

I/O node

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

IPMI

Intelligent Platform Management Interface. A self-contained hardware technology available on HP ProLiant DL145 servers that allows remote management of any node within a system.

L

Linux Virtual Server

See LVS

load file

A file containing the names of multiple executables that are to be launched simultaneously by a single command.

Load Sharing Facility

See LSF

local storage

Storage that is available or accessible from one node in the XC system.

LSF

Load Sharing Facility. The batch system resource manager on an HP XC system. LSF places a job in a queue and allows it to run when the necessary resources become available. LSF manages just one resource, which is the total number of processors designated for batch processing.

LSF can also run interactive batch jobs and interactive jobs. An LSF interactive batch job allows you to interact with the application while still taking advantage of LSF scheduling policies and features. An LSF interactive job is run without using LSF batch processing features but is dispatched immediately by LSF on the LSF execution host.

See also LSF execution host

LSF execution host

The node where LSF runs. A user’s job is submitted to the LSF execution host. Jobs are launched from the LSF execution host and are executed on one or more compute nodes.
