Use Cases¶
Proposed change¶
2 new volume drivers for iSCSI and FC should be developed, bridging Open stack commands to XtremIO management system (XMS) using XMS Rest API. The drivers should support the following Open stack actions:
Volume Create/Delete
Volume Attach/Detach
Snapshot Create/Delete
Create Volume from Snapshot
Get Volume Stats
Copy Image to Volume
Copy Volume to Image
Clone Volume
Extend Volume
