How can i plan Hardware specs specially harddisk and RAID for hyper-V virtual infrustructure

hi,

i going purchase physical box 4x600 gb sas drive plan run arround 40 vms on it.

now bit confused iops utilization , load can carry raid 10 in physical box.

my plan

1. configure raid 10

2. run arround 40 vms 20 gb each dynamic vhd.

please suggest me if there problem related performance face or suggest me performance hdd configuratin can run required vms

thanks & regards,

interesting.  i've never heard recommendation use different spindles in san.  in fact, of time recommendation build large shared volume spans multiple spindles, particularly in san, typical practice.  then, large single volume, create multiple vhds.  creating individual luns each vm creates lot of management overhead no performance gain.

as original post, going have live purchase.  not give indication io load created each of 40 vms going running, nor provide information on io capabilities of disks , raid controller.  so, not have problems whatsoever, or have 1 or 2 vms demand entire io capacity of system.

if have sample workload of vms generate in regards io, measure it.  math extrapolate load of 40 vms against measured ability of io subsystem.  if don't have sample workload, create one, measure it, , math.
