Intercluster relationship management

A system for creating an intercluster relationship between independent clustered storage systems, comprising:

• a memory;
• and
• an intercluster relationship component configured to:
• send, from a first clustered storage system, an initial contact request to a second clustered storage system, the initial contact request comprising a request to establish the intercluster relationship;
• provide first introduction information to the second clustered storage system;
• receive second introduction information from the second clustered storage system;
• establish the intercluster relationship based upon at least one of the first introduction information or the second introduction information;
• map 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
• map 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.

A non-transitory computer-readable device comprising processor-executable instructions that when executed perform a method 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, 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.

A method for creating an intercluster relationship between independent clustered storage systems, comprising:

• responsive to detecting a resource event at a first clustered storage system, by the first clustered storage system, sending an initial contact request to a second 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.
