This will now require a separate section "Use Cases". This was originally within "Problem description", but use cases seems to be missed when it was filled out. This will hopefully improve spec submission. Change-Id: I3615ca5ff5c46851e682739a8343242e2f1b0a8d

Use Cases
Proposed change
2 new volume drivers for iSCSI and FC should be developed, bridging Open stack commands to XtremIO managment 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
