Can we deploy two different cloud environment with a single external storage.I mean can we share the external storage SAN device (cinder) between two cloud environments.Already one cloud environment is deployed and running

I am not sure what you are asking. One Cinder instance for two clouds? Perhaps that works. I am not sure if Cinder likes two different Novas attaching volumes, but apart from that, why not?

One Storage backend for two Cinders? No problem, as long as the backend accepts two clients.

Yes one storage back end for two cinder from different Openstack environment. One openstack cloud is already deployed ,we were planning to use the same storage backend to deploy other cloud environment... Thanks a lot for your response

Perhaps a caveat. There might be unexpected problems; what I can think of, for example, is a Cinder driver for your backend that expects being the only entity that uses the storage system. Before you put it in production, get whatever information is available about the driver and test it.

Cinder backends use single database and message queue to keep disk metadata and provision in the cloud environment. Cinder disks are nothing without is metadata in terms of using in cloud.
