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 use the Pure Storage iSCSI Driver and Generic NFS Reference Driver.
• Volumes with external storage cannot be reverted from snapshots.
