Abstract

An aspect of the present invention is a method for retrieving reliability data in a system. The method includes coupling a device to the system, collecting the reliability data with the device and retrieving the reliability data from the device.

Claims

1. A method of retrieving reliability data of a system comprising:

coupling a data collection device to the system, the data collection device comprising a nonvolatile memory module and a jumper;

collecting the reliability data with the data collection device;

storing the reliability data in the nonvolatile memory module;

coupling a diagnostic tool to the data collection device; and

retrieving the reliability data from the data collection device;

wherein collecting the reliability data further comprises counting at least one event related to the system with the device; and

wherein the data collection device comprises a capacitor coupled to a counter and a power supply, and wherein the capacitor stores adequate power to complete write operations in the event the power supply is turned off.

2. The method of claim 1 wherein retrieving the reliability data with the device further comprises:

retrieving a total number of hours of operation for a subassembly in the system; and

retrieving a number of times the subassembly has been activated.

3. The method of claim 2 wherein the data collection device includes a jumper and coupling a diagnostic tool to the device further comprises:

coupling the diagnostic tool to the jumper; and

powering the data collection device from the diagnostic tool.

4. The method of claim 1 wherein retrieving the reliability data further comprises:

retrieving the reliability data via a network.

5. The method of claim 1 further comprising managing at least one redundant subassembly in the system using the reliability data.

6. A device for monitoring a system comprising:

a counter for counting at least one event related to the system; and

a memory coupled to the counter for storing data therefrom wherein the memory is capable of being accessed by another system in order to retrieve the stored data; and

a jumper that provides an input/output connection to the memory and a power input to power the device;

a capacitor coupled to a counter and a power supply, wherein the capacitor stores adequate power to complete write operations in the system in the event the power supply is turned off.

7. The device of claim 6 wherein the memory comprises a non-volatile EEPROM.

8. The device of claim 6 wherein the device further comprises a controller coupled to the memory.

9. The device of claim 6 wherein the device comprises a capacitor coupled to the counter and a power supply, and wherein the capacitor stores adequate power to complete write operations in the event the power supply is turned off.

10. The device of claim 6 wherein the device is capable of being coupled to a power supply within the system.

11. A data collection network comprising:

a plurality of subsystems;

a controller coupled to each of the plurality of subsystems;

a device displaced within each of the plurality of subsystems, wherein the device is coupled to the controller and includes

a counter for counting at least one event related to the system;

a memory coupled to the counter for storing data therefrom

a jumper that provides an input/output connection to the memory and a power input to power the device; and

wherein the memory is capable of being accessed by another system in order to retrieve the stored data;

wherein the device comprises a capacitor coupled to the counter and a power supply, and wherein the capacitor stores adequate power to complete write operations in the event the power supply is turned off.

12. The network of claim 11 wherein the device of each of the plurality of subsystems is coupled to the controller via a multiplexing mechanism.

13. The network of claim 11 wherein the plurality of subsystems comprises at least one of the following:

hot-pluggable hard drive assemblies;

hot-pluggable power supplies;

system boards;

blade modules;

chassis;

hot-pluggable fan assemblies;

backplanes;

expansion boards;

processor modules;

memory;

toner cartridge; and

projector lamps.

14. The network of claim 11 wherein the network further comprises a central system coupled to the plurality of subsystems via the controller.

15. The network of claim 14 wherein the controller is capable of being accessed by a remote system via the Internet.

16. An event monitoring mechanism comprising:

a counter for counting at least one event related to the system wherein the counter includes a non-volatile EEPROM memory for storing data;

a capacitor coupled to the counter for supplying power to the device,

wherein the is capacitor coupled to the counter and a power supply, and wherein the capacitor stores adequate power to complete write operations in a device in the event the power supply is turned off;

a diode coupled to the capacitor for preventing the capacitor from supplying a voltage to components on the system; and

a System Management Bus controller coupled to the counter wherein the controller is capable of being accessed by another system in order to retrieve the stored data.

17. The mechanism of claim 16 wherein the at least one event comprises a total time that the system is active.

18. The mechanism of claim 16 wherein the at least one event comprises a total number of times that the system is activated.

19. The mechanism of claim 16 wherein the device is capable of being coupled to a power supply within the system.

20. The mechanism of claim 19 wherein the counter counts the number of times that the power supply is activated.

21. The mechanism of claim 16 wherein the System Management Bus controller can be accessed by the system.

22. The mechanism of claim 21 wherein the System Management Bus controller is capable of being accessed by a remote system via the Internet.
