You may be in the right forum.

Depending on what you want to cluster, Unix might work MUCH better than Micro$oft.

To actually answer the question...

No, you really do not have to have the same exact hardware, at east not in a Windows cluster though it is best practice to have the same spec's on all your nodes.

You need to consider this...

Assuming you have a DL380G4 and a DL360G4. The 380 has 12GB ram andthe 360 has 6GB ram. You can cluster the 2 systems, and make the 380 your primary active node. But if you have to failover, you will be running on a server that has less resources then your primary.

At the very least, you should have the same amount of memory and other resources needed to support the clustered application. If you want to go overboard on the primary and have JUST enough on the standby, it would work. Not as good, but it would work.

See this page:

http://www.microsoft.com/windows2000/techinfo/planning/server/clustersteps.asp

"All hardware should be identical, slot for slot, card for card, for all nodes. This will make configuration easier and eliminate potential compatibility problems."

Oops!

compare that to VMS clustering:

ANY system running VMS can cluster with ANY other system running VMS, as long as the VMS versions are no more than one version level different, up to a supported maximum of 96 nodes....

Proost.

Have one on me.

That happens only with Microsoft.

With trucluster of Red Hat Cluster, or any other cluster for Linux, the machines doesn't have to be "the same".
