EMC VNX Plugin for Fuel
EMC VNX plugin
EMC VNX plugin for Fuel extends Mirantis OpenStack functionality by adding support for EMC VNX arrays in Cinder using iSCSI protocol. It replaces Cinder LVM driver which is the default volume backend that uses local volumes managed by LVM.
Requirements
| Requirement | Version/Comment |
|---|---|
| Mirantis OpenStack compatibility | >= 7.0 |
Limitations
Since only one storage network is available in Fuel 6.x on OpenStack nodes, multipath will bind all storage paths from EMC on one network interface. In case this NIC fails, the communication with storage is lost.
Installation Guide
EMC VNX configuration
Before starting a deployment you have to preconfigure EMC VNX array and connect it properly to the environment. Both EMC SP IPs and all iSCSI ports should be available over storage interface from OpenStack nodes. To learn more about EMC VNX configuration, see the official EMC VNX series documentation
EMC VNX configuration checklist:
- create username/password
- create at least one storage pool
- configure network for A and B Service Processors
- configure network for all iSCSI ports
EMC VNX plugin installation
To install EMC VNX plugin, follow these steps:
-
Download the plugin from Fuel Plugins Catalog
-
Copy the plugin on already installed Fuel Master node; ssh can be used for that. If you do not have the Fuel Master node yet, see Quick Start Guide:
# scp emc_vnx-2.0-2.0.0-0.noarch.rpm root@<Fuel_master_ip>:/tmp -
Log into the Fuel Master node. Install the plugin:
# cd /tmp # fuel plugins --install emc_vnx-2.0-2.0.0-0.noarch.rpm -
Check if the plugin was installed successfully:
# fuel plugins id | name | version | package_version ---|---------|---------|---------------- 1 | emc_vnx | 2.0.0 | 2.0.0
EMC VNX plugin configuration
- Create an environment with the default backend for Cinder.
- Enable the plugin on the Settings tab of the Fuel web UI and fill in form
fields:
- username/password - access credentials configured on EMC VNX
- SP A/B IP - IP addresses of the EMC VNX Service Processors
- pool name (optional) - a name of the EMC VNX storage pool on which all Cinder volumes will be created. Provided storage pool must be available on EMC VNX. If pool name is not provided then EMC VNX driver will use a random storage pool available on EMC VNX. You can also use a Volume Type OpenStack feature to create a volume on a specific storage pool. For more information, see Multiple pools support
- Deploy the environment without a Cinder node. All required Cinder services are run on Controller nodes.
Release Notes
This is the first release of the plugin.
