HP XC Clustering Software
The SVA runs HP XC System Software Version 3.0 clustering software. The SVA uses HP XC for the following key system management tasks:
•Installing and reinstalling a uniform set of software on visualization nodes.
•Booting and shutting down the cluster.
•Managing user accounts and user directories across the cluster.
•Naming each of the nodes in the cluster and determining which nodes are up and running.
•Serializing application use of the cluster.
