In the past i was in charge of specing and setting up a Hyper-V server. Back then I chose to run four 4TB drives in RAID 10, in order to have redundancy and speed. Unfortunately, when running 10-14 VMs I think the drives are really limiting performance.
Now, I’ve been tasked with getting a new server and it looks like it’ll need ~8TB of usable storage. I’d like to know if Hyper-V Server 2016 supports tiered storage. We’re a fairly small company and can’t exactly afford to drop enough cash to buy 16TB (8 usable, 8 redundant) worth of server-grade SSDs. But of course, I also don’t want the machine to slow to a crawl when multiple VMs start hitting the disks.
I was thinking that four 4TB hard drives with a 1-2TB SSD cache might work well if Hyper-V supports it. Do you guys know if that would work, or if there’s another way to speed up disk performance without dropping several grand on SSDs?
