I've read about the performance issues with dfferencing disks but I still think there is a solid place for them and thats the os boot partition. If I'm going to have 20 vms on a csv based volume I don't won't to waste the 20+ gigs per guest just for the os boot. If I get a good base disk with all of the most used applications installed and have the pagefile located somewhere else I don't think the delta's would be that great thus it should not create a performance issue. Also in a SAN based csv volumes does it make any sense in having the pagefile go to a seperate csv volume? Any opinions on this? thanks
