Patent ID: 8489793

Claim:
A computer program product for implementing connected input/output (I/O) hub configuration and management, the computer program product comprising: a non-transitory storage medium readable by a processing circuit and storing instructions for execution by the processing circuit for performing a method, the method comprising: configuring a first I/O hub in wrap mode with a second I/O hub, the first and second I/O hubs communicatively coupled to one another via a wrap cable; and generating data traffic on a main computing subsystem that includes the first and second I/O hubs, comprising: converting, via the first I/O hub, a request to implement a transaction to an I/O device-readable request packet and transmitting the I/O device-readable request packet over the wrap cable; converting, via the second I/O hub, the I/O device-readable request packet into a system readable request and transmitting the system readable request over a system bus, the system readable request addressed to a system memory; in response to receiving, at the second I/O hub, a response to the system readable request from the system memory, converting, via the second I/O hub, the response to an I/O device-readable response packet, and transmitting the I/O device-readable response packet over the wrap cable; and converting, via the first I/O hub, the I/O device-readable response packet into a system readable response packet, and transmitting the system readable response packet over the system bus to a processor that initiated the request to implement a transaction.
