Abstract
A system and method for transparent data replication of one or more data containers over migrating virtual servers (vfilers) operating on physical storage systems is provided. A mirroring (or other replication) procedure associated with a vfiler generates an entry in a mirror table maintained by one or more appropriate mirroring applications executing on the physical storage systems. The mirror table identifies source and destination 'owners' of a replicated data container by vfiler instead of only by physical storage system. Thus, when a vfiler is migrated from a source physical storage system ('source') to a destination physical storage system (“destination”), the mirroring application may continue to perform mirroring operations on the data containers at a per vfiler level to thereby improve the utility of migration of the vfiler among the storage systems.
