Abstract
An apparatus and method for monitoring and controlling the internal state of a computer system, in particular, a computer server. The computer system includes one or more subsystems. These subsystems provide one or more management signals at a system management slot. The computer system also includes an I/O bus slot coupled to an I/O bus of the computer system. A system management agent is coupled to both the system management slot and the I/O bus slot. The system management agent includes a processor and a memory system coupled to the processor. The system management agent also includes a communications interface coupled to the processor and the memory system.

7. A method for monitoring and controlling the internal state of a computer server having an input/output bus and one or more subsystems, the input/output bus containing input/output signals, the input/output signals coupled to an input/output connector, the one or more subsystems providing one or more management signals to a system management connector, the management signals including at least one signal which is not one of the input/output signals, both the input/output connector and the system management connector coupled to a system management agent, the system management agent comprising a processor, a memory system, and a communication interface, the method comprising the steps of:
-
(a) providing both the input/output bus signals and the one or more system management signals to the systems management agent; and (b) executing instructions stored in the memory system of the system management agent for monitoring and controlling the state of the computer system, the executing of instructions performed by the processor of the system management agent; wherein the system management agent is an add-in board and the step (a) is perfected by inserting the system management agent add-in board into the computer server in order to couple the input/output signals and the system management signals simultaneously to the system management agent. - View Dependent Claims (8, 9, 10, 11, 12)
