REDUCING ETHERNET LATENCY IN A MULTI-SERVER CHASSIS

摘要

A system includes a multi-server chassis, a midplane within the chassis, and a switching device connected to the midplane. The switching device has serial communication lanes including a lane for each of multiple server bays within the chassis, and has a network communication port for connecting to an external network. The system further comprises servers, wherein each server is received in a server bay and has a serial communication interface connected to the midplane. The midplane includes serial communication pathways, wherein each serial communication pathway provides serial communication between the serial communication interface of one of the servers and one of the serial communication lanes of the switching device. The switching device converts messages to and from an external network so that a serial expansion bus standard is used over serial communication pathways in the midplane and a network communication standard is used over the external network.
