I have a customer with the following set up, does it make sense...? A large VM machine, 64 GB with SAN
Then a sql server machine that has Partition C:\ on LUN with Raid 5 Partition D:\ on LUN with Raid 1
Both Partitions are in a Disk array of 10 discs, with Raid 10. In this disc array there are also other Maschines with Partitions on a LUN with Raid 5.
In total on the VM machine there are a total of 22 VMs running!!
My largest concern, other than there being soo many VMs running simultaneously is the redundant nature of Raid 5 in a raid 10 array etc. Is that normal??
