Abstract:
1. A computer system, comprising: a chassis configured for mounting in a rack and comprising one or more chassis air inlets on one end of the chassis and one or more chassis air outlets on the other end of the chassis; one or more circuit board assemblies coupled to the chassis; one or more hard disk drives coupled to the chassis; and one or more air passages under at least one of the hard disk drives, wherein at least one of the air passages comprises one or more air inlets and one or more air outlets, wherein at least one of the inlets is configured to direct at least a portion of the air downwardly into at least one of the passages, wherein the at least one passage is configured to allow air to move from the at least one air inlet to at least one of the air outlets, wherein at least one of the one or more air passages under the hard disk drives is at least partially downstream from one or more circuit board assemblies on the chassis, wherein the air passages are located such that at least a portion of the air in the computer system flows in through the chassis air inlets on the one end of the chassis, above and over at least one of the one or more circuit board assemblies on the chassis, into at least one of the air passages under the at least one hard disk drive, and out through the chassis air exits on the other end of the chassis.
