Setting Storage Tiers for Datastores

Six levels of storage tier costs are available to be applied to each datastore or datastore cluster managed by Commander. By default, Storage Tier 1 is applied to all datastores and datastore clusters.

Datastores — When you set the storage tier for a datastore, the tier is also assigned to the datastore's actual location on disk (which is displayed as the Location property for a datastore). You can't assign a storage tier to a datastore that's part of a datastore cluster; you must assign the storage tier at the datastore cluster level. When you change a datastore's storage tier, the costs of VMs on that datastore are automatically recalculated.

Datastore clusters — When you set the storage tier for a datastore cluster, all datastores in that cluster are assigned the same storage tier. When you move a datastore into a datastore cluster, the datastore is automatically assigned the storage tier of the cluster. When you move a datastore out of a datastore cluster, the datastore retains the storage tier of the parent cluster.

When you configure storage tiers, you must ensure that datastores are available to back them.

When a user requests a VM that has with no explicit storage tier set, automated deployment uses the default storage tier specified by the cost model applied to the deployment destination. If the deployment destination for the service request doesn't target a datastore for this storage tier, the automated deployment will fail. For example, if a highly available datastore isn't assigned to the default storage tier for a VM configured to be highly available, automated deployment will fail. Always configure the default storage tier to be backed by datastores for vCenter, SCVMM highly available storage, and SCVMM non-HA storage. If this configuration isn't possible due to the way you use storage, contact Customer Support for other configuration options.

To assign a storage tier to a datastore or datastore cluster:

  1. Select the datastore in the Storage view (from the tree or the Datastores tab), or in the Infrastructure or Applications view (from the Datastores tab).

    Or, select a datastore cluster in the Storage view (from the tree or from the Datastore Clusters tab).

  2. On the Summary page, select Actions >Set Storage Tier.
  3. In the Set Storage Tier dialog, select the appropriate storage tier, and click OK.
