If there are several shared datastores available to hosts in a cluster, and VMs in some datastores start suffering from higher than usual storage I/O latencies, it is likely the time to address this by spreading the load across multiple shared datastores. It is not a trivial task, the idea is to find the right combination of VMs and datastores where the space, IOPS and latencies represent the right state – so VMs can get as much IOPS and space as needed and latencies are minimal.
