  • mgmt01 - central web management server.
  • mon01 - main monitoring server running Zabbix.
  • cfgdb01 - configuration database server running Apache ZooKeeper.

The root accounts in each virtual server have the first compute node’s public SSH key set during installation and therefore are accessible from first compute node via SSH.
