Managing external storages

Besides the local compute storage, you can integrate your compute cluster with a third-party storage compatible with OpenStack. This will allow you to use an enterprise-grade storage solution, as well as isolate storage from your compute nodes.

OpenStack provides multiple drivers for different storages. A set of available operations on volumes is limited by the driver capabilities and can be checked in the Cinder Driver Support Matrix.

Limitations

• The currently supported storages only include those that have the OpenStack Cinder iSCSI driver and use the Generic NFS Reference Driver (any storage with NFS support). For the full list of available iSCSI drivers, refer to the Cinder Driver Support Matrix.
• Volumes with external storage cannot be reverted from snapshots.
