Computer systems that acquire a plurality of statuses of non-normally operating hard disk drives

Abstract

A computer system includes multiple hard disk devices, a hard disk device backplane, an information management unit, a middle backplane and multiple motherboards. The hard disk device backplane is coupled to and configured to manage the hard disk devices. The information management unit, coupled to the hard disk device backplane, is configured to acquire statuses of the hard disk devices. The middle backplane is coupled to the hard disk device backplane. The motherboards, coupled to the information management unit and the middle backplane, respectively have a baseboard management controller. When the operating system is loaded for operation on the motherboards, the baseboard management controllers are coupled to the hard disk device backplane via the middle backplane to acquire the statuses of the hard disk devices. When the motherboards are not operated normally, the baseboard management controllers acquire the statuses of the hard disk devices via the information management unit.
