Abstract: The present disclosure is directed to a configurable extension space for a computer server or node blade that has the ability to expand data storage or other functionality to a computer system while minimizing any disruption to computers in a data center when the functionality of a computer server or a node blade is extended. Apparatus consistent with the present disclosure may include multiple electronic assemblies where a first assembly resides deep within an enclosure to which an expansion module may be attached in an accessible expansion space.

Abstract: Example implementations relate to a pressure regulator assembly for a closed fluid loop of a CDU. The pressure regulator assembly has a cylinder having an internal volume, and first and second hollow pistons slidably connected to the cylinder to split the internal volume into a first volume portion having cooling fluid, a second volume portion having driver fluid, and a third volume portion having compressible matter. The first volume portion is fluidically connected to the closed fluid loop. The first hollow piston is reciprocated by the compressible matter to maintain operating pressure of the cooling fluid in the closed fluid loop. The second hollow piston is driven by the driver fluid in response to predefined pressure drop of the cooling fluid during predefined time period, to inject additional cooling fluid from the first volume portion into the closed fluid loop to restore pressure level of cooling fluid to operating pressure.

Abstract: Example implementations relate to a cool fluid reservoir for managing loss of cool fluid in a coolant distribution unit (CDU). The cool fluid reservoir includes a cylinder which has an internal volume defined between an inlet and outlet, and a hollow piston that is slidably connected to the cylinder via one of the inlet or outlet to split the internal volume into a first volume portion filled with the cool fluid and a second volume portion filled with driver fluid. The first volume portion is fluidically connected to a closed fluid loop of the CDU via the hollow piston and other one of the inlet or outlet. The hollow piston is slidably driven by the driver fluid to reduce the first volume portion and inject a portion of the cool fluid from the first volume portion into the closed fluid loop based on an operating pressure of the cool fluid.
