A high availability (HA) deployment of two Citrix® Command Center™ appliances can provide uninterrupted management of network devices. You configure one appliance as the primary node and the other as the secondary node. The primary node manages the network devices while the secondary node acts as a passive node. The secondary node becomes primary and takes over if the original primary node fails for any reason.
The primary node updates its health status at predefined intervals in a database table. Also, at predefined intervals, the secondary node checks the database for the status of the primary node. If a health check fails, the secondary node rechecks the health a predefined number of times, after which it determines that the primary node is not functioning normally. The secondary node then takes over as the primary (a process called failover). After a failover, the original secondary is the primary node. After the administrator corrects the problem on the original primary appliance and restarts it, the original primary appliance becomes the secondary node.
