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


  1. 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.

  2. 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.


Restart cinder-volume service after modifying cinder.conf.

Sample minimum back end configuration

enabled_backends = vpsa

zadara_vpsa_host =
zadara_vpsa_port = 80
zadara_user = vpsauser
zadara_password = mysecretpassword
zadara_use_iser = false
zadara_vpsa_poolname = pool-00000001
volume_driver = cinder.volume.drivers.zadara.ZadaraVPSAISCSIDriver
volume_backend_name = vpsa
