Fuel plugin for ScaleIO-Cinder clusters as a Cinder backend

ScaleIO-Cinder plugin for Fuel extends Mirantis OpenStack functionality by adding support for ScaleIO clusters for Cinder backend.

Problem description

Currently, Fuel has no support for ScaleIO clusters as block storage for OpenStack environments. ScaleIO-Cinder plugin aims to provide support for it. This plugin will configure OpenStack environments with an existing ScaleIO cluster

Proposed change

Implement a Fuel plugin that will configure the ScaleIO-Cinder driver for Cinder on all Controller nodes and Compute nodes. All Cinder services run on controllers no additional Cinder node is required in environment.

Performance Impact

The ScaleIO-Cinder storage clusters provide high performance block storage for OpenStack environment, and therefore enabling the ScaleIO-Cinder driver in OpenStack will greatly improve peformance of OpenStack.

Other deployer impact

None

Developer impact

None

Implementation

The plugin generates the approriate cinder.conf to enable the ScaleIO-Cinder cluster within OpenStack. There are scaleio driver and filter required files, the plugin contains the files and will copy them to the correct location.

Cinder-volume service is installed on all Controller nodes and Compute nodes. All instances of cinder-volume have the same “host” parameter in cinder.conf file. This is required to achieve ability to manage all volumes in the environment by any cinder-volume instance.
