Glossary

A

Administrative Network

The private network within the XC system that is used for administrative operations.

admin branch

The half (branch) of the Administrative Network that contains all of the general-purpose admin ports to the nodes of the XC system.

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 XC system.

branch switch

A component of the Administrative 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 XC system.

Console Branch

A component of the Administrative Network. The half (branch) of the Administrative Network that contains all of the console ports of the nodes of the XC system. This branch is established as a separate branch to enable some level of partitioning of the Administrative 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 Control Protocol

See DHCP

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.
