Greetings, Just wonder if Microsoft would support an exchange 2007 cluster consisting of two Dell Poweredge 2950's and 4 PowerEdge 1950's. I heard somewhere that while it will work you may not be able to get support from Microsoft if you runa cluster with different hardware. Thanks for any info Brian
