ViPR 2.0 works with all third-party arrays listed by OpenStack as working with Cinder using either Fibre Channel or IP protocols, whose list can be found here. The ViPR Compatibility Matrix only lists those that have been EMC-tested and certified with ViPR 2.0 to this point.  That does not mean that others won’t work, just that they haven't been certified. Additional third-party arrays may be EMC-tested and certified based on customer demand. If and when that occurs, these third-party arrays will be added to those already supported by EMC and listed on the ViPR Compatibility Matrix.  
Why does the ViPR Compatibility Matrix only show IBM SVC and NetApp as supported block arrays for OpenStack Cinder? I thought ViPR supported many more third-party arrays with OpenStack Cinder.
