Hello,   Dell doesn't certify OpenStack w/Equallogic.   It's the underlying software like Cinder that does the work with storage arrays.  The driver uses EQL Group CLI commands, the syntax of which hasn't changed, except for new features.    [URL] [URL]  So there should be no issue with any recent version of firmware.  It's good to be running something current, or at least near current as a general rule.   Regards,   Don   
Do you have the Compatibility Matrix List of Openstack on Equallogic? I want to know information of the recommended PS Firmware version and supported PS model about Openstack,kilo,Liberty and Mitaka. Thanks and best regards,
