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

EMC VMAX Driver Update
https://blueprints.launchpad.net/cinder/+spec/emc-vmax-driver-juno-update
This driver is an enhancement of the EMC SMI-S driver for VMAX. In Juno, the support for VNX will be removed from the SMI-S driver. Moving forward, this driver will support VMAX only. Some new features will be added for VMAX.
Problem description
The existing EMC SMI-S iSCSI and FC driver has some missing features for VMAX. In previous release, support for Extend Volume and Create Volume from Snapshot were only implemented for VNX. In Juno, these features will be added for VMAX.
In previous release, masking view, storage group, and initiator group need to be created ahead of time. In Juno, this will be automated.
Use Cases
Proposed change
The following features will be added to the SMI-S based driver to support VMAX:
- Extend volume
- Create volume from snapshot
- Dynamically creating masking views, storage groups, and initiator groups
- Striped volumes
- FAST policies
