Abstract

A fault tolerant method by which individual components of a server are monitored and controlled through independent, programmable microcontrollers interconnected through a microcontroller network. An external agent can control and monitor the microcontrollers by extending the interconnection network beyond the physical server. Intervention of the server operating system software is not required and is not utilized for the access and control operations. The method includes the processes running on a remote interface so as to enable communication between the microcontroller network and an external modem that communicates with a remote client machine. The remote interface also provides for connection to a local client machine.

Claims

1. A method of external management of the environmental conditions of a computer, the method comprising the acts of:

connecting a remote interface to a first computer and a second computer;

providing an environmental management command at the second computer directed to the first computer;

encapsulating the command in a communications protocol;

transmitting the encapsulated command to the remote interface;

communicating the command received by the remote interface to the first computer, and

performing the command on the first computer.

2. The method of claim 1, wherein the act of performing the command includes the act of establishing a secure mode in the computer environment.

3. The method of claim 1, wherein the act of performing the command includes the act of requesting data from a component of the first computer.

4. The method of claim 1, wherein the act of performing the command includes the act of sending data to a component of the first computer.

5. The method of claim 1, wherein the act of communicating the command includes the act of storing command data in a memory associated with the remote interface.

6. The method of claim 1, further including the act of providing a response to the second computer through the remote interface based on results of the command.

7. The method of claim 6, wherein the act of providing a response includes the act of storing response data in a memory associated with the remote interface.
