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.
Claims22
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.
6 more elements
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.
3 more elements
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.
6 more elements
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.
