availability set
An association of two individual nodes so that one node acts as the first server and the other
node acts as the second server of a service.

availability tool
A software product that enables system services to continue running if a hardware or software
failure occurs by failing over the service to the other node in an availability set.

branch switch
A component of the Administration Network. A switch that is uplinked to the root switch and
receives physical connections from multiple nodes.

cluster
A set of independent computers combined into a unified system through system software and
networking technologies.
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.
having to know individual nodes names to connect and log in to the HP XC system.
CMDB
Configuration and management database. Constructed during HP XC system installation, the
CMDB is a MySQL database that stores information about the nodes, hardware, and software
configuration, and network connectivity. This database runs on the node with the node
management role.

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.
