Abstract

Systems and methods for managing faults within a high speed network employing wide ports. Exemplary embodiments include a system including a switch module coupled to an end device, the switch device and the end device each have a plurality of PHYs, each of the PHYs on the switch module coupled to a corresponding PHY on the end device, a plurality of wide port cables connected between the switch module and the end device, wherein the coupling of the switch module and the end device defines a wide port, and a process residing on the wide port, the process configured to diagnose faults on the PHYs and having instructions to identify an operational PHY, instruct the operational PHY to take command over the remaining PHYs in the wide port, execute diagnostic sub-routines within the port to identify failed PHYs and report diagnostic data to the operational PHY.

Claims

1. A system for managing faults within a high speed network employing wide ports, the system comprising:

a switch module coupled to an end device, the switch device and the end device each have a plurality of PHYs, each of the PHYs on the switch module coupled to a corresponding PHY on the end device;

a plurality of wide port cables connected between the switch module and the end device, wherein the coupling of the switch module and the end device defines a wide port; and

a process residing on the wide port, the process configured to diagnose faults on the PHYs and having instructions to;

identify an operational PHY;

instruct the operational PHY to take command over the remaining PHYs in the wide port;

execute diagnostic sub-routines within the port to identify failed PHYs; and

report diagnostic data to the operational PHY.

2. The system as claimed in claim 1 wherein the switch module and the end device each comprise:

a data processor; and

a switch coupled to the data processor and the plurality of PHYs.

3. The system as claimed in claim 2 wherein each data processor further comprises a data buffer, a packet controlled and a protocol controller.

4. The system as claimed in claim 3 wherein the switch module further comprises a switch processor coupled to the data processor residing on the switch module.

5. The system as claimed in claim 4 wherein the end device further comprises a target processor coupled to the data processor residing on the end device.

6. The system as claimed in claim 5 wherein the process is configured to generate a diagnostic PHY loopback transfer on the wide port.

7. The system as claimed in claim 6 wherein the process is configured to route data traffic over remaining good PHYs within the wide port.

8. The system as claimed in claim 7 wherein the switch residing on the switch module is an initiator to which failed PHY information is transferred by the process.

9. A method for managing faults within a high speed network employing wide ports, the method comprising:

configuring a wide port on the high speed network;

determining whether to run a diagnostic process within the wide port;

in response to determining to run the diagnostic process, defining a command PHY within the wide port;

running the diagnostic process;

identifying a failed PHY on the wide port; and

reporting failed PHY information to an initiator on the wide port.

10. The method as claimed in claim 9, wherein the high speed network comprises:

a switch module coupled to an end device, the switch module and the end device each have a plurality of PHYs, each of the PHYs on the switch module coupled to a corresponding PHY on the end device; and

a plurality of wide port cables connected between the switch module and the end device, wherein the coupling of the switch module and the end device defines the wide port.

11. The method as claimed in claim 10 wherein the diagnostic comprises instructions to:

instruct the command PHY to take command over the remaining PHYs in the wide port;

execute diagnostic sub-routines within the port to identify failed PHYs; and

report diagnostic data to the initiator.

12. The method as claimed in claim 11 wherein the diagnostic process is configured to generate a diagnostic PHY loopback transfer on the wide port.

13. The method as claimed in claim 12 wherein the diagnostic process is configured to:

route data traffic to all PHYs

determine if individual PHYs are good and to report a good status;

determine if individual PHYs are bad and to report a bad status if the bad PHY is able to report its status; and

to detect a PHY interface timeout if all PHYs are bad and unable to report status.

14. The method as claimed in claim 13 wherein the switch module comprises:

a switch processor; and

a data processor coupled to the switch processor,

wherein the data processor is coupled to the initiator and to the PHYs residing on the switch module, the initiator receiving the diagnostic data from the wide port as generated by the diagnostic process.

15. The method as claimed in claim 14 wherein the diagnostic data includes the failed PHY information.

16. A computer readable medium having computer executable instructions for performing a method for managing faults within a high speed network employing wide ports, the method comprising:

configuring a wide port on the high speed network;

determining whether to run a diagnostic process within the wide port;

in response to determining to run the diagnostic process, defining a command PHY within the wide port;

running the diagnostic process;

identifying a failed PHY on the wide port; and

reporting failed PHY information to an initiator on the wide port.

17. The computer readable medium as claimed in claim 16 wherein the method further comprises:

instructing the command PHY to take command over the remaining PHYs in the wide port;

executing diagnostic sub-routines within the port to identify failed PHYs; and

reporting diagnostic data to the initiator.

18. The computer readable medium as claimed in claim 16 wherein the diagnostic data includes the failed PHY information.

19. The computer readable medium as claimed in claim 16 wherein the method further comprises generating a diagnostic PHY loopback transfer on the wide port.

20. The computer readable medium as claimed in claim 16 wherein the method further comprises routing data traffic over remaining good PHYs within the wide port.
