A system for providing continuous cooling to a storage rack, including a storage rack, including a first storage node and a second storage node; a first cooling loop including a first cooling distribution unit (CDU); a second cooling loop including a second cooling distribution unit (CDU); a first inlet switching valve coupled between the first storage node and each of the first and the second CDUs; a second inlet switching valve coupled between the second storage node and each of the first and the second CDUs; wherein, when the first cooling loop experiences a failure, a state of the first inlet switch and a state of the second inlet switch is adjusted to i) prevent the first CDU from providing cooling of the first storage node and the second storage node, ii) allow only the second CDU to provide cooling of the first storage node and the second storage node.

Providing continuous cooling to a storage rack

An information handling system includes two or more heat-generating devices and a liquid-assisted air cooling (LAAC) assembly to cool at least some of the devices. The LAAC assembly includes a radiator, first and second pumps connected in series with the radiator. The LAAC assembly further includes first and second cold plates enclosing first and second CPUs or another suitable heat generating device. The first and second cold plates are connected in parallel between an inlet of the first pump and an outlet of the second pump. In this configuration, the serial connected pumps in combination with the parallel connected cold plates provide 1+1 pump redundancy while delivering cold coolant from the radiator outlet to both heat generating devices such that neither heat cold plate receives pre-heated coolant from the other cold plate.

Liquid-assisted air cooling design with parallel cold plates and serial pumps

A highly available and modular cooling distribution unit (CDU) includes a heat exchange module and a pair of redundant pump modules, all configured to occupy a designated rack space that is comparable to rack space required for a conventional 1&#xd7;CDU without redundancy. The heat exchange module may be fluidically coupled to one or more rack information handling resources via liquid coolant conduits, manifolds and accompanying valves, sensors, etc. In at least one embodiment, the heat exchange module includes a heat exchanger to dissipate heat from a liquid coolant and a fan assembly to move heated air in proximity to the heat exchanger. Each pump module is coupled to the heat exchange module and configured to circulate liquid coolant through a closed loop circuit that includes the heat exchanger, the liquid coolant conduits and manifolds, and information handling resources.

Embodiments include expansion cards that provide a specialized capability, such as networking, when coupled to an Information Handling System (IHS). The expansion card embodiments include a printed circuit board (PCB) of a first width and a heat sink located on a top surface of the PCB. The expansion cards also include pins located on a distal end of the PCB, where the pins are received by a connector of the IHS. Embodiments include a button operable for ejecting a latch of the expansion card from a stored position in response to pressing the button. When ejected, the latch remains within the first width of the PCB, thus supporting high-density configurations of expansion cards. The ejected latch is further operable for an administrator to easily pull the expansion card from the IHS. Expansion card embodiments may also include vents that provide pathways for ventilating heated air away from the heat sink.
