ScaleIO Fuel plugin

ScaleIO plugin for Fuel extends Mirantis OpenStack functionality by adding support for deploying and configuring ScaleIO clusters as block storage backend.

Problem description

Currently, Fuel has no support for ScaleIO clusters as block storage backend for OpenStack environments. ScaleIO plugin aims to provide support for it. This plugin will deploy a ScaleIO cluster and configure the OpenStack environment to consume the block storage services from ScaleIO.

Proposed change

Implement a Fuel plugin that will deploy a ScaleIO cluster and configure the ScaleIO Cinder driver on all Controller and Compute nodes.

Performance Impact

The ScaleIO storage clusters provide high performance block storage for OpenStack environments. Therefore, enabling the ScaleIO plugin in OpenStack will greatly improve performance of OpenStack block storage operation.

Other deployer impact

None

Developer impact

None

Implementation

This plugin contains several tasks:

  • The first task installs the ScaleIO cluster. All nodes will contribute to the storage pool by the amount specified by the user in the configuration process. Controllers 1, 2, and 3 will contain the MDM and the Gateway in HA mode.
  • The second task configures the ScaleIO gateway to avoid interference with the Horizon dashboard.
  • The third task enables HA in the ScaleIO gateway instances.
  • The fourth task configures all Compute nodes to use ScaleIO backend.
  • The fifth task configures all Controller nodes to use ScaleIO backend.
  • The sixth task creates and configures a Cinder volume type with the parameters from the ScaleIO cluster.

Work Items

  • Implement the Fuel plugin.
  • Implement the Puppet manifests.
  • Testing.
  • Write the documentation.

Dependencies

  • Fuel 6.1.

Testing

  • Prepare a test plan.
  • Test the plugin by deploying environments with all Fuel deployment modes.

Documentation Impact

  • Deployment Guide (how to install the storage backends, how to prepare an environment for installation, how to install the plugin, how to deploy an OpenStack environment with the plugin).
