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 storage systems include those that utilize the OpenStack Cinder driver with support for either the iSCSI or Fibre Channel (FC) protocol, as well as storage systems using the Generic NFS Reference Driver (any storage solution with NFS support).
