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. The full list of available storage drivers with a set of available operations on volumes limited by the driver capabilities is reflected in the Cinder Driver Support Matrix.
The currently supported storages include those that have the OpenStack Cinder iSCSI driver, OpenStack Cinder Fibre Channel (FC) driver, or use the Generic NFS Reference Driver (any storage with NFS support).
Limitations
- Volumes with external storage cannot be reverted from snapshots.
