Patent ID: 7813121

Claim:
A computer system, comprising: a chassis defining a front and a rear, the chassis including a vertically oriented midplane, the midplane including a plurality of front module slots for receiving front electronic modules from the front of the chassis, and a plurality of rear module slots for receiving rear electronic modules from the rear of the chassis; a cooling system, the cooling system being configured to generate an upwardly-directed front air flow within the chassis directed at selected ones of the front electronic modules and being configured to generate an upwardly-directed rear air flow within the chassis directed at selected ones of the rear electronic modules, the front air flow being separate from and independent of the rear air flow; wherein the cooling system includes an inlet separator baffle and an exhaust separator baffle, and wherein the inlet separator baffle, the midplane and the exhaust separator baffle are collectively configured in the chassis such that the front air flow and the rear air flow are isolated from one another and are independently controllable.
