Can an MSCS cluster be built from servers that use Digital Alpha processors?
Yes. Windows NT Server Enterprise Edition is available for both Intel and Alpha processors. Digital has already validated several cluster configurations for MSCS using Alpha-based servers. Note that MSCS does not permit mixing Intel-based and Alpha-based servers in the same cluster. This is because there are some differences in the on-disk format used by each type of processor, so MSCS would not be able to failover disks from one to the other.
