Guide to the EMC VNX Plugin for Fuel

EMC VNX plugin for Fuel extends Mirantis OpenStack functionality by adding support for EMC VNX arrays in Cinder using iSCSI protocol. It replaces Cinder LVM driver which is the default volume backend that uses local volumes managed by LVM. Enabling EMC VNX plugin in Mirantis OpenStack means that all Cinder services are run on Controller nodes.

Requirements

Requirement Version/Comment
Fuel 7.0 and higher
EMC VNX array It should be configured and deployed. It should be reachable via one of the Mirantis OpenStack networks.

Limitations

  1. Since only one storage network is available in Fuel 7.x on OpenStack nodes, multipath will bind all storage paths from EMC on one network interface. In case this NIC fails, the communication with storage is lost.
  2. Fibre Channel driver is not supported.
