LCS orchestrator device/expansion device secondary circuit board system

An Information Handling System (IHS), comprising:

• a primary circuit board including a host processing system that provides an operating system for a Logically Composed System (LCS);
• an orchestrator device including an orchestrator processing system that performs orchestration operations for the LCS;
• an expansion device that performs at least one function for the LCS;
• and
• a secondary circuit board that includes:
• an orchestrator connector subsystem that is connected to the orchestrator device;
• a primary connector that is connected to the primary circuit board and coupled via the secondary circuit board to a first orchestrator connector in the orchestrator connector subsystem to provide an orchestrator/host coupling used by the orchestrator processing system to operate as a host endpoint to the host processing system;
• and
• a first expansion connector that is connected to the expansion device and coupled via the secondary circuit board to a second orchestrator connector in the orchestrator connector subsystem to provide an orchestrator/expansion coupling used by the expansion device to operate as an orchestrator endpoint to the orchestrator processing system.

A method for coupling a Logically Composed System (LCS) orchestrator device and an expansion device to a primary circuit board using a secondary circuit board, comprising:

• connecting, by an orchestrator connector subsystem on a secondary circuit board, to an orchestrator device that is configured to perform orchestration operations for a Logically Composed System (LCS);
• providing, by a primary connector on the secondary circuit board that is coupled via the secondary circuit board to a first orchestrator connector in the orchestrator connector subsystem, an orchestrator/host coupling by connecting to a primary circuit board that includes a host processing system that provides an operating system for the LCS;
• operating, by an orchestrator processing system in the orchestrator device using the orchestrator/host coupling, as a host endpoint to the host processing system;
• providing, by a first expansion connector on the secondary circuit board that is coupled via the secondary circuit board to a second orchestrator connector in the orchestrator connector subsystem, an orchestrator/expansion coupling by connecting to an expansion device that performs at least one function for the LCS;
• operating, by the expansion device using the orchestrator/expansion coupling, as an orchestrator endpoint to the orchestrator processing system.
