Problem description
|
|
===================
|
|
|
|
This is a new Cinder driver that would enable Open Stack to work on top of
|
|
XtremIO storage.

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
|
|
