With net8 you can configure load-balancing options. If you can't use net8, use MTS using dynamic instance registration on the listeners. You need a listener on every node that is part of the cluster.

In the latter case your clients should address by the cluster name, not by the individual node names. When you use failover and (or) load balancing from the client, you need to address the individual nodes. Check the net8 and ops installation guides for details.

failsafe is AFAIK some M$ thing on NT.
