Plugin description
Pure Storage plugin for Fuel extends Mirantis OpenStack functionality by adding support for Pure Storage FlashArray block storage array.
The Pure Storage FlashArray is an iSCSI and Fibre Channel capable block storage device used as a Cinder backend
Requirements
| Requirement | Version/Comment |
|---|---|
| Mirantis OpenStack compatibility | >= 8.0 |
| Access to FlashArray VIP via cinder-volume node | |
| Access to FlashArray VIP via compute/cinder-volume nodes | |
| iSCSI/FC initiator on all compute/cinder-volume nodes |
Limitations
Pure Storage configuration
Prior to deployment ensure the following items are complete:
- For an iSCSI implementation ensure the Pure Storage FlashArray can route 10G Storage Network to all Compute nodes as well as the Cinder Control/Manager node.
- For an FC implementation ensure the fibre Channel Zone Manager is configured correctly within the Openstack deployment
- Create an AD/LDAP account for the Pure Storage cluster to use as the OpenStack Administrator account (if no AD/LDAP use the 'pureuser' account).
- Obtain the management VIP address for the Pure Storage FlashArray
Pure Storage Cinder plugin installation
All of the needed code for using Pure Storage in an OpenStack deployment is included in the upstream OpenStack distributioni with the exception of the Pure Storage Python SDK which is installed by this plugin. There are no additional libraries, software packages or licenses required beyond using this plugin.
Pure Storage plugin configuration
No additional configuration is required for the Pure Storage Cinder plugin, but the Fibre Channel Zone Manager must be configured correctly if FC is selected as the block storage protocol to be used by the Pure Storage FlashArray
