In a nutshell, I have a test 2012 R2 cluster (2-node) attached by fibre to a SAN. The SAN at present is configured with 2 volumes, one RAID 10 and the other RAID 5.
2 questions really. Is it best practice for each guest to have 2 virtual hard disks, one for OS and the other for data. If so, would it be appropriate to put the OS vhdx on the RAID 10 and the data on RAID 5?
I'm trying to get a general rule of thumb rather than cater for say specifics such as SQL server. I'm really looking at file servers and the like initially.
