Abstract
A computer system has a plurality of sub-systems each comprising a serial interface and a buffer device coupled with the serial interface for buffering crash data sent by the serial interface having an external serial output. The system further comprises a management controller coupled with the external serial output of the buffer device to retrieve data buffered during a crash.
Claims15
Computer system comprising:
- a plurality of sub-systems each comprising:
- a serial interface;
- and
- a buffer device coupled with the serial interface for buffering crash data sent by the serial interface having an external serial output;
- a management controller coupled with the external serial output of the buffer device to retrieve data buffered during a crash.
Method of operating a computer system comprising a plurality of sub-systems each running independently an operating system and a management controller coupled with the plurality of sub-systems, the method comprising the steps of:
- upon a system crash outputting a crash dump file through a serial port of the sub-system;
- buffering the crash dump file;
- generating a control signal for a management controller;
- upon request by the management controller coupling the management controller with the sub-system;
- and
- transferring the buffered crash dump file to the management controller.
Computer system comprising:
- a plurality of independent sub-systems each running a operating system that outputs a crash dump through a serial port and generates a control signal upon a system crash;
- a management controller having a control input, a serial bus interface coupled with a communication line, and a serial input;
- wherein each sub-system comprises:
- a microcontroller having a control input, a memory, and a serial input port coupled with the serial port and a serial output port;
- a controller unit having a serial bus interface for coupling with the management controller and an input for receiving the control signal and generating an external control signal fed to the control input of the management controller and an output for an internal control signal fed to the microcontroller;
- a switch controlled by the controller unit for coupling the serial output port with the external communication line.
