XProtect Management Server Failover elements

XProtect Management Server Failover consists of the following elements:

Failover cluster - It consists of two independent computers that work together to maintain high availability of the management server, log server, event server, and SQL Server. If one of the computers fails, the other computer in the cluster takes over the workload of running the VMS server components.

Primary and secondary computers - Typically, the primary computer is the computer you have a running VMS installation on. To configure the failover cluster, you install a VMS product on the secondary computer that mirrors the one on the primary computer.

Nodes - The failover cluster consists of two computers called nodes. The primary computer is referred to as Node 1, and the secondary computer is referred to as Node 2. The names of the nodes do not change but they can have different states. During normal operation, the node the VMS servers run on is in PRIM state and the standby node is in SECOND state.
