Problem description =================== This is a new Cinder driver that would enable Open Stack to work on top of XtremIO storage. The following diagram shows the command and data paths. :: +----------------+ +--------+---------+ | | Command | | | | Path | Cinder + | | Nova +---------------> | Cinder Volume | | | | | | | | | +-----+----------+ +--------+---------+ | | | | | | | | | | +------------------+ | | | | Command +--+ | Path + | XtremIO Driver | | | | | | | | +------+-----------+ | | | | | + | XtremIO Rest API | | v | | +----------------+ | +-----------------+ | | | | | | Compute | | | | | | +----> XtremIO | | | Data Link | storeage | | +-----------------------------------------+ | +----------------+ +-----------------+ 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 Alternatives ------------ None Data model impact ----------------- None REST API impact --------------- None Security impact --------------- None Notifications impact -------------------- None Other end user impact --------------------- None Performance Impact ------------------ This feature will use native snapshot so the user can expect great speed up to all snapshot/clone related actions. Other deployer impact --------------------- None Developer impact ---------------- None Implementation ============== Assignee(s) ----------- Primary assignee: shay-halsband Other contributors: None Work Items ---------- Implement REST API client to XMS Implement Logic for each functionality to support both iSCSI and FC Dependencies ============ Testing ======= Continuous integration as required for all drivers in the Juno timeframe Documentation Impact ==================== Add documntation on how to install and use the drivers.
