I am building out a server for our software tech support group. They will be running VM Server on this to host many VM images. It's an older Dell 6600, quad proc, 24GB machine. They've requested that all drives attached to the RAID controller be put into a RAiD 5 array, and formatted as one large drive C: (7 disks, comes out to 850+ GB). I personally don't like creating servers like this- but they want to maximize on their disk space. Is there a compelling reason to partition a system drive (30-40GB) for Drive C: and then leave the rest for data/programs, especially since it's one large RAID 5 array and everythings hitting the same spindles?
