SQL Server Cluster

    In a SQL Server Cluster configuration, does the physical nodes have to have the same processor count?

    I have two physical nodes. Both currently have 2 4-core 2.4 Ghz processor. I would like to replace one node with 2 6-core 2.8 GHz processor (12 twelve cores) and move the other two 4-core 2.4 Ghz to the other node giving it 4 4-core processors (8 total cores)

    I have automatically set processor afffinity mask for all processors.

    When the SQL instance rolls and restarts, it should change understand the change in processors and everything should be fine...I hope.

    Does this sound like an exceptable configuration?

    Thanks

    As long as you stay insde the same processor family (i.e. 7000's or 5000's) and don't try to mix (i.e. 5000 with 7000) you should be ok. With server 2008 they have really relaxed the restrictions and allow you to mix much more openly between processor families.
