US 6,807,599 B2 · Computer system I/O node for connection serially in a chain to a host

Abstract

A computer system I/O node. An input/output node for a computer system includes a first receiver unit configured to receive a first command on a first communication path and a first transmitter unit coupled to transmit a first corresponding command that corresponds to the first command on a second communication path. The input/output node also includes a second receiver unit configured to receive a second command on a third communication path and a second transmitter unit coupled to transmit a second corresponding command that corresponds to the second command on a fourth communication path. Further, the input/output node includes a bridge unit coupled to receive selected commands from the first receiver and the second receiver and configured to transmit commands corresponding to the selected commands upon a peripheral bus.

A computer system comprising:

one or more processors;
one or more input/output nodes connected together and to a given one of said one or more processors serially in a chain, each of said input/output nodes including:
a first receiver unit configured to receive a first command from said given one of said one or more processors on a first communication path;
a first transmitter unit coupled to transmit a first corresponding command that corresponds to said first command to a next one of said one or more input/output nodes in said chain on a second communication path;
a second receiver unit configured to receive a second command from said next one of said one or more input/output nodes in said chain on a third communication path;
a second transmitter unit coupled to transmit a second corresponding command that corresponds to said second command to said given one of said one or more processors on a fourth communication path;
and
a bridge unit coupled to receive selected commands from said first receiver and said second receiver and configured to transmit commands corresponding to said selected commands upon a peripheral bus.
