Hi,
I am setting up a new Hyper-V 2012 R2 host. I got a 8TB RAID5 dedicated to the planned virtual file server data disk. I have another RAID on the host for the host OS and yet another RAID on the host that will house the VMs including the OS disk for the file server.
Our backup solution does not support raw disks, so please do not suggest I use raw disks.
My question is:
Purely from a performance perspective, should I split the 8TB data disk into 2 (or more) fixed VHDXs at 4TB each or am better off with just 1 fixed VHDX at 8TB?
Any other reasons why several VHDXs might be better than just one big one?
Please don't tell me what's supported by Microsoft, I know whats supported, I'm asking what's best for performance and if there are any other reasons why several VHDX is a better option over 1 big.
Thanks.
