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