Administrator Guide

• From the Servers view in the Navigation pane of Storage Manager, select Servers. Use the Create Datastore function to create a

datastore of the type VVOL. When you create a datastore using this function, you can also create a new storage container to be

associated with the datastore, or map to an existing storage container to be associated with the datastore.

NOTE: This is the recommended method.

After a storage container has been created, you can use vCenter to create a datastore and map it (mount it) to the storage container. Then

the datastore can be used to create VVol-based VMs.

Details about storage containers and VVols shown in the Summary tab when you select the Severs node.

How Storage Container Options Aect vCenter Advertised Capabilities

The creation of a storage container includes specifying options such as the use of compression, deduplication, encryption, and snapshots

and Storage Center Storage Proles. When the storage container creation completes. these options are advertised as capabilities to

vCenter. The following VASA version 2.0 system storage capabilities are supported by Unisphere Central, and are shown on the vCenter

Summary tab are shown under Capability Sets and in Default Proles in vCenter for individual datastores.

• compression

• dedupe

• encryption

• snapshotCapable

• SCstorageProle

NOTE

: These capabilities apply only to VVol datastores. They do not apply to legacy VMFS datastores.

A VMware administrator can use storage capabilities to create VM Storage Policies in vCenter.

Data Reduction Options for VVols

You can specify data reduction options when creating storage containers. These options are advertised (made available) to the VMware

administrator during VM Storage Prole creation.

When you use Unisphere Central to create storage containers, you can optionally set these data reduction options:

• Deduplication Allowed

• Compression Allowed

Specifying one or both of these options indicates the data reduction preferences for VMs that are then created.

You can also specify options for Data Reduction Input:

• None

• Compression

• Deduplication with Compression

These options are presented as checkboxes on the Create Storage Container wizard.

NOTE

: Even if the Compression Allowed and Deduplication Allowed checkboxes are selected, selecting the None prole option

results in no action being taken.

You can also select the Default Data Reduction Prole, if one has been specied using the User Preferences.

After a storage administrator creates a storage container with data reduction options specied, these options are advertised (shown as

being selected) on the VM Storage Prole wizard when a VMware administrator creates a storage prole. If you edit the storage

container’s Data Reduction option, you also change the advertised capabilities that are visible in the VM Storage Prole.

For information about using VM Storage Proles, see the VMware vCenter documentation.
