Abstract
Certain aspects direct to a system having at most four service processors (SP's). Each of the at most four SP's is assigned with a logical unit number (LUN) of 0 to 3. When the SP receives a message packet, the SP identifies the message packet based on the header of the message packet. The header uses a LUN field to identify a corresponding SP as a destination of the message packet. For the LUN 0 SP, when the message packet is identified as a request message packet for the LUN 0 SP, the SP processes the request message packet to generate a corresponding response message packet. When the message packet is identified as a request message packet for other SP's (LUN 1-3), the SP saves a copy of the header of the request message packet for later response use, and forwards the request message packet to the destination.
