    Domino R5 Clustering Question Relative T

    Locked

    by jroberts ·

    We’re going to be setting up 2 Domino R5 servers and they’ll be clustered. What does the TCP/IP addressing look like in this scenario? Does each server have its own IP address? Or does the cluster itself have its own IP address? We’re thinking that the cluster should have its own IP address so that all incoming traffic can be routed to the cluster entity and we’d get true benefit from load balancing. If our ISP has to direct traffic to one of the servers in the cluster, that seems to defeat the purpose.

    Anyone know?

      I assume you’re asking about an NT or W2K Network Load Balancing cluster (as opposed to a server cluster – different animal).

      The cluster has a virtual IP address to which all the traffic is directed. What happens behind the scenes is that all the server NICs hear the request and then decide amongst themselves who will respond to it and establish the connection.

      So you’re thinking correctly… the cluster does have its own address.

      Depends what clustering you implement. I’m most familiar with Vinca. Each physical machine will need an IP. When a failover occurs, the secondary machine normally “takes over” the service requests for the primary, however, sometimes this doesn’t work smoothly. The best way I’ve found is to get a third IP and set it up as a clustered IP. When a failover occurs, the IP address is then tranferred to the secondary machine. This should solve any DNS/WINS issues.
