The following diagram illustrates the components of a cluster group, including sample IP
addresses. For a list of required IP addresses and node names, see “List of IP Addresses and
Network Names” on page 31

If you are already using clusters, the Avid Interplay Engine will not interfere with your
current setup.
How Server Failover Works
Server failover works on two different levels:
• Failover in case of hardware failure
• Failover in case of network failure
Hardware Failover Process
When the Microsoft cluster service is running on both systems and the server is deployed in
cluster mode, the Interplay Engine and its accompanying services are exposed to users as a
virtual server (or cluster application). To clients, connecting to the clustered virtual Interplay
Engine appears to be the same process as connecting to a single, physical machine. The user or
client application does not know which node is actually hosting the virtual server.
