We're running OES2 NetWare (NW65SP8) and we're interested in setting up Cluster Services in a 2-node cluster for a file server to provide higher availability. I have some high-level questions we need to understand before we decide how to move forward, and I was hoping for some assistance here:

* I assume the server OS needs to be the same on both servers, yes?

* Does the server hardware need to be identical for both servers in the cluster?

* Can GroupWise be clustered? We also have a GroupWise 8 server we're considering clustering.

* Does the data have to be on a shared volume, or does cluster Svcs replicate data between local volumes on the 2 servers?

Thanks in advance for any info on these questions.
