IPMI dual-domain controller

A computer board set, comprising:

• a central processing unit;
• and a dual-domain microcontroller operating simultaneously as a satellite management controller to receive a request for system management information and to provide system management information of the computer board sets through a bus interface, and as a local baseboard management controller to receive the system management information from the computer board set and to provide the system management information to the central processing unit through a computer board set bus interface.

A Intelligent Platform Management Interface (IPMI) compliant computer chassis, comprising:

• a computer central processing unit;
• and a computer board set having a dual-domain controller, wherein the dual-domain controller operates as a central baseboard management controller to collect system management information from the IPMI compliant computer chassis and to provide system management to the computer central processing unit through a bus interface.

A Intelligent Platform Management Interface (IPMI) compliant computer chassis, comprising:

• a computer central processing unit;
• and a central baseboard management controller to monitor the IPMI compliant computer chassis, to make requests for system management information from at least one computer board sets, to receive system management information from the at least one computer board sets, and to provide the system management information to the computer central processing unit, wherein a computer board set includes a dual-domain controller to operate simultaneously as a satellite management controller to receive a request for the system management information and to provide the system management information of the computer board set through a bus interface to the central baseboard management controller, and as a local baseboard management controller to receive the system management information from the computer board set and to provide the system management information to the computer board set.

A network of Intelligent Platform Management Interface (IPMI) complaint computer chassis, comprising:

• a first computer chassis including a central baseboard management controller to monitor the IPMI compliant computer chassis, to make requests for system management information from a computer board set, and to receive the system management information from the computer board set;
• and a second computer chassis including a computer board set having a dual-domain controller operating simultaneously as a satellite management controller to receive a request for the system management information and to provide the system management information of the computer board set through an Intelligent Chassis Management Bus (ICMB) to the central baseboard management controller, and as local baseboard management controller to receive the system management information from the computer beard set, and to provide the system management information to the computer board set, wherein the first computer chassis is connected to the second computer chassis via the ICMB.
