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.

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.

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).
|
|
* User Guide (which features the plugin provides, how to use them in the
|
|
deployed OpenStack environment).
|
|
* Test Plan.
|
|
* Test Report.
