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).
