I'm running into trouble understanding the normalized I/O QoS settings in Hyper-V after I've done some testing.
I would like my VM to be able to use at least around the equivalent of 2 disks in RAID-0, so I set the limit to 500 IOPS in Hyper-V. I know this is a bit on the positive side, but that's not exactly the problem. The problem is this... When measuring performance of the disks, I see, on synthetic tests and the underlying hardware (3par storage), the VM indeed consumes around 500 IOPS max. The problem is, the disk also only gets around 4 MB/s total througput when copying files. While I would like a max of 500 IOPS for the disk I also want the server to have a throughput of around 100 MB/s. But you can understand, giving the server 12500 IOPS max isn't an option. How can I solve this?
