I recently had a great question on some of the differences in virtual machine disk presentation from one of our amazing clients, and I thought I’d share the answer here because it’s a common question that I receive.
Some hypervisors (including some hyper-converged compute platform vendors who shall remain nameless) do not give you much flexibility in the way storage is presented to a VM. You pick the VM and click to add drives. That’s it. No knobs to turn, no mess, no fuss. It’s meant to be easy, and for almost all situations, that’s just fine.
But, that might not be the completely optimal way to configure a VM that is hungry for I/O (such as a large SQL Server), if you have the option to configure it a bit more closely.
