Enabling Storage DRS
Storage DRS is a mechanism to balance space utilization and I/O load on datastores in a datastore cluster by migrating (Storage vMotion) the VMs. Storage DRS can only be enabled on a datastore cluster. To learn how to create a datastore cluster read the recipe Creating a datastore cluster.
It also influences the initial placement of the VMs on the datastores. For Storage DRS's I/O load balancing to work, all the hosts accessing the datastores should be of ESXi Version 5.0 or above. Also, the cluster cannot contain replicated and non-replicated datastores.
In this recipe we will learn how to enable Storage DRS.
How to do it…
The following procedure will guide you through the steps required to enable SDRS on a datastore cluster:
Use the vSphere Web Client to connect to the vCenter Server.
Navigate to Home | Storage.
Select the datastore cluster from the left pane; navigate to the Manage tab and then to the Settings sub tab:
Click on Storage DRS and click on Edit… to bring up the...
