Abstract: A cooling system including redundant fan controllers. The cooling system includes a first fan controller coupled to control a first plurality of fans and a second fan controller coupled to control a second plurality of fans. During operation, the first plurality of fans and the second plurality of fans operate concurrently. The first fan controller and the second fan controller are each configured to monitor the first and the second plurality of fans and to detect a failure in any of the first and the second plurality of fans. Further, in response to detecting a failure of a fan of the first plurality of fans, the second fan controller is configured to increase an operating speed of a corresponding fan of the second plurality of fans.

Abstract: A method, device, and system for automatic fail over of system controllers. A system controller includes a processor, a memory, and a plurality of I/O controllers. Each I/O controller is configurable with a plurality of I/O connections to another system controller. Each of the plurality of I/O controllers is further configurable with an I/O connection to each of one or more monitored devices. The method includes booting a plurality of system controllers configured as a primary system controller and at least one secondary system controller and booting one or more domains in the computer system from the primary system controller. The method also includes updating a system configuration on the primary system controller and updating the system configuration on the secondary system controller from the primary system controller.
