Oracle ZFS Storage Appliance iSCSI Driver¶
Include the URL of your launchpad blueprint:
https://blueprints.launchpad.net/cinder/+spec/oracle-zfssa-cinder-driver
ZFSSA ISCSI Driver is designed for ZFS Storage Appliance product line (ZS3-2, ZS3-4, ZS3-ES, 7420 and 7320). The driver provides the ability to create iSCSI volumes which are exposed from the ZFS Storage Appliance for use by VM instantiated by Openstack’s Nova module.
Problem description¶
Currently there is no support for ZFS Storage Appliance product line from Openstack Cinder.
Use Cases¶
Proposed change¶
iSCSI driver uses REST API to communicate out of band with the storage controller. The new driver would be located under cinder/volume/drivers/zfssa, and it would be able to perform the following:
Create/Delete Volume
Extend Volume
Create/Delete Snaphost
Create Volume from Snapshot
Delete Volume Snapshot
Attach/Detach Volume
Get Volume Stats
Additionally a ZFS Storage Appliance workflow (cinder.akwf) is provided to help the admin to setup a user and role in the appliance with enought privileges to do cinder operations. Also, cinder.conf has to be configured properly with zfssa specific properties for the driver to work.
