How to ensure that each instance uses the disk of its host?

Hi,

I have a set of nodes and each of them is simply compute node + storage node. I don't have the cluster nodes solely for storage.

I want to make sure that if a vm 1 is running on a compute node A, then the vm 1 uses the disks attached on the node A. (I want it not to consume network I/O bandwidth for disk write operations.)

Many thanks for any helpful information.
