Abstract: A cooling system is provided which includes, for instance, a coolant circulation loop, one or more primary coolant pumps, and a fill and drain pump. The primary coolant pump(s) is coupled to facilitate circulating coolant through the coolant circulation loop, and the fill and drain pump facilitates selective filling of the cooling system with the coolant, or draining of the coolant from the cooling system. The fill and drain pump is integrated with the cooling system as a backup coolant pump to the primary coolant pump(s), and circulates the coolant through the coolant circulation loop responsive to an error in the primary coolant pump(s). The primary coolant pump(s) and fill and drain pumps may be different types of pumps, and the cooling system further includes a control system for automatically activating the fill and drain pump upon detection of an error in the primary coolant pump(s).

Abstract: An apparatus is provided which includes a changeable cover assembly sized to cover, at least in part, an air outlet side of an electronics rack. The cover assembly, when positioned at the air outlet side of the rack, redirects and vents airflow egressing from the air outlet side. The cover assembly includes a frame and at least one vent cover. The frame has at least one opening through which air egressing from the electronics rack passes, and the vent cover(s) is coupled to the frame and overlies, at least in part, the opening(s) in the frame to facilitate redirecting and venting the air passing through the frame. The at least one vent cover is changeable to change a direction of the vented air. For instance, the vent cover(s) may be reversible, or otherwise adjustable or changeable, to change the direction of vented air egressing from the cover assembly.

Abstract: One aspect is a method that includes applying a plurality of incrementally varying voltage targets to a plurality of power phase converters operating in parallel between a source voltage rail and a load voltage rail. A phase temperature of each of the power phase converters is monitored. The phase temperature of each of the power phase converters is compared to a thermal adjustment limit. One or more of the power phase converters are adjusted to reduce an associated output current based on determining that at least one of the power phase converters exceeds the thermal adjustment limit. Power phase converter adjustments can be performed in a balanced manner such that a net sum voltage at the load voltage rail is substantially unchanged after the adjustments.

Abstract: An apparatus is provided for cooling an electronic system, which includes one or more electronic components across which air passing through the system flows. A cooling unit provides, via a coolant loop, system coolant to cool the electronic component(s), and to an air-to-liquid heat exchanger is coupled to the coolant loop downstream of the electronic component(s) to cool, in primary, liquid-cooling mode, air passing through the system. In primary, liquid-cooling mode, the cooling unit provides cooled system coolant to cool the electronic component(s), and provides system coolant to the air-to-liquid heat exchanger to cool at least a portion of air passing through the electronic system, and in a secondary, air-cooling mode, system coolant flows from cooling the electronic component(s) to the air-to-liquid heat exchanger for rejecting, via the system coolant, heat from the electronic component(s) to air passing across the air-to-liquid heat exchanger.
