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
