For the best experience with vVols functionality, you must follow specific guidelines.
vVols supports the following capabilities, features, and VMware products:
- With vVols, you can use advanced storage services that include replication, encryption, deduplication, and compression on individual virtual disks. Contact your storage vendor for information about services they support with vVols.
- vVols functionality supports backup software that uses vSphere APIs - Data Protection. Virtual volumes are modeled on virtual disks. Backup products that use vSphere APIs - Data Protection are as fully supported on virtual volumes as they are on VMDK files on a LUN. Snapshots that the backup software creates using vSphere APIs - Data Protection look as non-vVols snapshots to vSphere and the backup software.
Note: vVols does not support SAN transport mode. vSphere APIs - Data Protection automatically selects an alternative data transfer method.
For more information about integration with the vSphere Storage APIs - Data Protection, consult your backup software vendor.
- vVols supports such vSphere features as vSphere vMotion, Storage vMotion, snapshots, linked clones, and DRS.
- You can use clustering products, such as Oracle Real Application Clusters, with vVols. To use these products, you activate the multiwrite setting for a virtual disk stored on the vVols datastore.
For more details, see the knowledge base article at http://kb.vmware.com/kb/2112039. For a list of features and products that vVols functionality supports, see VMware Product Interoperability Matrixes.
- Because the vVols environment requires vCenter Server, you cannot use vVols with a standalone host.
- vVols functionality does not support RDMs.
- A vVols storage container cannot span multiple physical arrays. Some vendors present multiple physical arrays as a single array. In such cases, you still technically use one logical array.
- Host profiles that contain vVols datastores are vCenter Server specific. After you extract this type of host profile, you can attach it only to hosts and clusters managed by the same vCenter Server as the reference host.
