Fuel plugin for Datera as a Cinder backend

The Datera plugin for Fuel extends Mirantis OpenStack functionality by adding support for Datera EDF in Cinder using the iSCSI protocol.

Problem description

Currently, Fuel has no support for Datera EDF as block storage for OpenStack environments. The Datera plugin aims to provide support for it.

Proposed change

Implement a Fuel plugin that will configure the Datera driver for Cinder on all Controller nodes.

Performance Impact

The Datera EDF provides high performance block storage for OpenStack environments, and therefore enabling the Datera driver in OpenStack will greatly improve the peformance of OpenStack.

Other deployer impact

The deployer should make sure the IP of the management VIP is correct, prior to deploying the Fuel plugin to the controllers. If this is not done the VIP needs to altered and the cinder service will have to be restarted.

Developer impact

None

Implementation

The plugin generates the approriate cinder.conf to enable the Datera EDF within OpenStack. The Datera v2 API driver, which is required as v1 is deprecated, is bundled with the Fuel plugin.

There are two tasks the plugin performs on nodes with the Cinder role: * Install the v2 API driver. * Update cinder.conf to reflect the correct settings enabling the driver.
