Abstract

A method for implementing connected input/output (I/O) hub configuration and management includes configuring a first I/O hub in wrap mode with a second I/O hub. The hubs are communicatively coupled via a wrap cable. The method further includes generating data traffic on a computing subsystem that includes the hubs. Generating traffic includes: converting, via the first hub, a request to implement a transaction into an I/O device-readable request packet and transmitting the request packet over the wrap cable; converting, via the second hub, the I/O device-readable (IODR) request packet into a system readable request and transmitting the request over a system bus; converting, via the second hub, the response to an IODR response packet, and transmitting the response packet over the wrap cable; and converting, via the first hub, the IODR response packet into a system readable response packet, and transmitting the response packet over the system bus.
