Scalable global namespace through referral redirection at the mapping layer

摘要: Client computers, a namespace server, and file servers are linked in data network so that the server provides clients with NFS or CIFS access to virtual system including files stored servers, also migration of between fashion transparent client using CIFS. The computers storage arrays storing area have high speed block mapping protocol. redirects metadata request protocol from appropriate when is not being migrated, otherwise denies migrated reverts access.
