Storage DRS is a mechanism to balance Space Utilization and I/O load across Datastores in a Datastore Cluster. The balancing is achieved by migrating Virtual Machines between datastores using Storage vMotion.
Storage DRS can only be enabled on a datastore cluster.
Datastores (VMFS/NFS) can be grouped to form a datastore cluster. Storage DRS monitors the datastore space utilization and SIOC metrics to redistribute VM files among datastores in a datastore cluster. It also provides initial placement recommendations when deploying VMs into the datastore cluster.
In this recipe, we will learn how to create a datastore cluster and enable Storage DRS on it.
