Cinder driver Deployment cinder.conf How does it work? Allowed_backends=coprhd-fc,coprhd-iscsi [coprhd-fc] …. [coprhd-iscsi] Driver uses CoprHD CLI CLI makes REST API calls to API service Credentials are stored in cinder.conf in plaintext (cinder issue) Project, Tenant and Varray specified in cinder.conf New backend entry needed for every combination Volume Types cinder type-create Platinum cinder type-key set Platinum ViPR:VPOOL=“VirtualPool1” cinder type-key set Platinum volume_backend_name=coprhd-fc cinder type-create Gold cinder type-key set Gold ViPR:VPOOL=“VirtualPool2” cinder type-key set Gold volume_backend_name=coprhd-iscsi These volume types are visible in the Horizon UI

CoprHD with cinder southbound History Needed a way to expand the support matrix Considered various alternatives Why cinder? Large number of tested drivers Why the API approach? Considered using the python drivers directly Not feasible due to library depedencies
