Policy-based management of storage functions in data replication environments

摘要

A method for managing storage functions in a data replication environment is disclosed. In one embodiment, such a method includes continually monitoring for changes to a storage configuration at a secondary site. Upon detecting changes to the storage configuration at the secondary site, the method transmits remote metadata describing the changes to the primary site and stores the remote metadata at the primary site. The method then initiates a storage management function at the primary site which is mirrored to the secondary site. In order to perform the storage management function, the method reads the remote metadata at the primary site to determine the storage configuration at the secondary site. The method then performs the storage management function at the primary site in a way that takes into account the storage configuration at the secondary site. A corresponding apparatus, system, and computer-readable medium are also disclosed and claimed herein.

1. A system comprising:
a data replication system comprising a primary site and a secondary site, wherein production data is mirrored from the primary site to the secondary site; a secondary host system to perform the following:
continually monitor changes to a storage configuration at the secondary site;upon detecting changes to the storage configuration at the secondary site, transmit remote metadata describing the changes to the primary site for storage at the primary site; a primary host system to perform the following:
initiate a storage management function at the primary site that is replicated to the secondary site;read the remote metadata at the primary site to determine the storage configuration at the secondary site; andperform the storage management function at the primary site in a way that takes into account the storage configuration at the secondary site.
