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.
To use Zadara Storage VPSA Volume Driver you will require:
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
.
