Re: Volume driver in Cinder by ISCSI way



EMC's volume driver (implemented in emc.py) is open source but EMC storage is not.  EMC volume driver allows users to provision EMC storage in OpenStack.  This is the same case with many other vendor provided drivers.  The EMC volume driver that is available currently supports iSCSI protocol on VNX and VMAX/VMAXe arrays.

I have a README for how to use this driver in Folsom.  See the following link:


We are still doing development for Grizzly, so I don't have a README yet.  You can take a look of the Folsom doc to get started.  Let me know if you have any questions.

To add another driver, you can just add it under cinder/volume/drivers like emc.py.

For development efforts, it is better to use openstack-dev list instead of this general openstack list.  You can also join #openstack-cinder IRC channel in freenode for online discussion with cinder developers.

Thanks for your help, that's very kind of you ;-)

EMC is not open-source code project, right? And Openstack support EMC
by iSCSI way. That is to say, iSCSI is the bridge to connect Openstack and
EMC, right? Could you please give me the docs of
I wanna understand how to realize EMC's iSCSI driver.

By the way, if i wanna add a driver(a block storage system by iSCSI way) for
Openstack Cinder, i should just add my driver file under the dir,
like emc.py, right?
