Creating a Failover Peer
The Failover object defines methods for two servers to share common address
pools and ensure continuous availability.
It defines a role of the Primary Server and the Secondary Server in event of
a system failure. During a prolonged failure of the Primary Server, the Secondary
Server recovers all the addresses that the Primary Server had available for
allocation, and begins to reuse them.
To create Failover:
- Select the service for which you want
to create the Failover Peer object.
- Specify a name
to identify the Failover Peer object.
- Specify the
IP Address of the Primary Server.
-
Specify the Port number of the Primary Server.
-
Specify the IP Address of the Secondary Server.
-
Specify the Port number of the Secondary Server.
-
Specify the Max Client Lead Time. This is the length of time for which a lease
may be renewed by either server without contacting the other. (Specify this on
the Primary Server. This cannot be specified on the Secondary Server).
-
Specify the Failover Split. This specifies the split between the Primary and
Secondary Servers for the purpose of load balancing.
