Zadara Storage VPSA volume driver

Zadara Storage, Virtual Private Storage Array (VPSA) is the first software defined, Enterprise-Storage-as-a-Service. It is an elastic and private block and file storage system which, provides enterprise-grade data protection and data management storage services.

The ZadaraVPSAISCSIDriver volume driver allows the Zadara Storage VPSA to be used as a volume back end storage in OpenStack deployments.

System requirements

To use Zadara Storage VPSA Volume Driver you will require:

Zadara Storage VPSA version 15.07 and above
iSCSI or iSER host interfaces

Supported operations

Create, delete, attach, and detach volumes
Create, list, and delete volume snapshots
Create a volume from a snapshot
Copy an image to a volume
Copy a volume to an image
Clone a volume
Extend a volume
Migrate a volume with back end assistance
Manage and unmanage a volume

Configuration

Create a VPSA pool(s) or make sure you have an existing pool(s) that will be used for volume services. The VPSA pool(s) will be identified by its ID (pool-xxxxxxxx). For further details, see the VPSA's user guide.
Adjust the cinder.conf configuration file to define the volume driver name along with a storage back end entry for each VPSA pool that will be managed by the block storage service. Each back end entry requires a unique section name, surrounded by square brackets (or parentheses), followed by options in key=value format.

Note

Restart cinder-volume service after modifying cinder.conf.
