Abstract:
1. A method for creating an intercluster relationship between independent clustered storage systems, comprising: sending, by a first clustered storage system, an initial contact request to a second clustered storage system operating independent of the first clustered storage system, the initial contact request comprising a request to establish the intercluster relationship; providing first introduction information to the second clustered storage system; receiving second introduction information from the second clustered storage system; establishing the intercluster relationship based upon at least one of the first introduction information or the second introduction information; mapping a first role between the first clustered storage system and the second clustered storage system, the first role defining a first set of operations available for the first clustered storage system to execute on the second clustered storage system utilizing the intercluster relationship, the first set of operations comprising a first operation that accesses non-cached data managed by the second clustered storage system; and mapping a second role between the second clustered storage system and the first clustered storage system, the second role defining a second set of operations available for the second clustered storage system to execute on the first clustered storage system utilizing the intercluster relationship, the second set of operations comprising a second operation that accesses non-cached data managed by the first clustered storage system.
