Claim 17:
18. An electronic rack, comprising:
a plurality of server chassis arranged in a stack, each server chassis having one or more server slots to receive one or more server blades; and
a plurality of coolant management units, each corresponding to one of the plurality of server chassis for connecting the server chassis to provide liquid cooling the one or more server blades of the corresponding server chassis, each coolant management unit comprising:
a server supply manifold to be coupled to a rack supply manifold to receive cooling fluid from a cooling fluid source, wherein the server supply manifold is to distribute the cooling fluid to the one or more server blades of the server chassis, wherein the coolant management unit is positioned on a rear side of the server chassis;
a server return manifold to be coupled to a rack return manifold, wherein the server return manifold is to receive vapor from the one or more server blades, wherein the cooling fluid is two-phase cooling fluid to extract heat from one or more servers and to evaporate into the vapor into the server return manifold, wherein the vapor is transmitted to an external condenser via the rack return manifold to be condensed back to a liquid form;
a power distribution bus to distribute power to the one or more servers; and
a controller to control a fluid pump coupled to the server supply manifold based on one or more signals received from one or more sensors.
