Abstract:
1. A method for maintaining an intercluster relationship, comprising: establishing an intercluster relationship between a first clustered storage system and a second clustered storage system, the first clustered storage system operating independent of the second clustered storage system; responsive to the establishing, receiving at the first clustered storage system a list of identifications for one or more resources available at the second clustered storage system to be utilized by the first clustered storage system; maintaining a local cache at the first clustered storage system, the local cache comprising the list of identifications; responsive to identifying a request, at the first clustered storage system, to perform an operation, evaluating the local cache to determine whether the second clustered storage system provides the first clustered storage system with access to a resource corresponding to the operation based upon a review of the list of identifications; and responsive to the evaluating indicating that the second clustered storage system provides the first clustered storage system with access to the resource, implementing the operation using the resource via the intercluster relationship.
