Introduction
This documentation provides instructions for installing, configuring, and using the Fuel EMC VNX plugin version 4.0.0.
The EMC VNX plugin for Fuel extends the Mirantis OpenStack functionality by adding support for the EMC VNX arrays in Cinder using the iSCSI protocol. It replaces Cinder LVM driver which is the default volume back end that uses local volumes managed by LVM. Enabling EMC VNX plugin in Mirantis OpenStack means that all the Cinder services are run on controller nodes.
