Guys, I need to spec out a new Hyper-V server and just wanted some general feedback / suggestions from the community on how to configure the storage as far as best performance.
I have a quote from our hardware vendor right now for the following:
OS (Hyper-V) partition: (2) 146GB SAS 15K drives in RAID-1
Storage partition (VMs will live here): (4) 1TB SAS 7.2K drives in RAID-5
SQL database partition (our SQL DBs will live here): (2) 128GB SSD drives in RAID-1
All partitions driven by a single IBM ServeRAID M5100 controller.
Is there a benefit to having the OS on a separate partition from the VMs? Do we need 15K drives for the OS partition, or would 10K or 7.2K drive be sufficient? Any other feedback / suggestions would be greatly appreciated.
Shaun
