ABSTRACT:
In one embodiment, a method for repairing a faulty cache element is provided. Once a monitored cache element is determined to be faulty, the system stores the repair information, and cache configuration in an EEPROM or non-volatile memory on the CPU module. Then the computer is rebooted. During the reboot, the faulty cache element is repaired by being swapped out for a spare cache element based on the information stored in the EEPROM or the non-volatile memory.
