Zadara VPSA Driver for OpenStack Manila

Zadara’s 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.

Manila VPSA driver provides a seamless management capabilities for
VPSA volumes, in this case, NFS & SMB volumes without losing the
added value provided by the VPSA Storage Array/Flash-Array.


  • VPSA Storage Array/Flash-Array running version 20.12 or higher.
  • Networking preparation – the Zadara VPSA driver for Manila support
    DHSS=False (driver_handles_share_servers), the driver does not handle
    the network configuration, it is up to the administrator to ensure
    connectivity from a manila-share node and the Openstack cloud to the
    VPSA Front-End network (such as neutron flat/VLAN network).
