Intercluster relationship management

摘要

Data storage and management systems can be interconnected as clustered systems to distribute data and operational loading. Further, independent clustered storage systems can be associated to form peered clusters. As provided herein, methods and systems for creating and managing intercluster relationships between independent clustered storage systems, allowing the respective independent clustered storage systems to exchange data and distribute management operations between each other while mitigating administrator involvement. Cluster introduction information is provided on a network interface of one or more nodes in a cluster, and intercluster relationships are created between peer clusters. A relationship can be created by initiating contact with a peer using a logical interface, and respective peers retrieving the introduction information provided on the network interface. Respective peers have a role/profile associated with the provided introduction information, which is mapped to the peers, allowing pre-defined access to respective peers.

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.
