Smart rack liquid cooling manifold system having integrated controller(s) providing server-level liquid telemetry monitoring, rack liquid flow control, and datacenter communicaton

An information processing system rack comprising:

• a rack frame divided into a plurality of rungs, each rung capable of supporting an information processing system node having an information processing system with one or more heat-generating electronic components;
• at least one cold plate assembly attached to the one or more heat-generating electronic components within the information processing system (IPS) at each corresponding IPS node to thermally cool the one or more heat-generating electronic components via a cooling liquid flow;
• and
• a rack liquid cooling manifold system comprising:
• a supply manifold comprising a supply control valve and a manifold intake port available for sealably coupling to a facility liquid supply to receive a cooling liquid and comprising more than one server supply ports each available for sealably coupling, for liquid transfer of the cooling liquid, to a respective cooling liquid supply input of a corresponding information processing system node;
• a return manifold comprising a facility liquid return port for sealably coupling to a facility return to exhaust the cooling liquid and comprising more than one server return ports, each available for sealably coupling, for exhaust liquid transfer, to a respective cooling liquid exhaust output of the corresponding information processing system node, the respective cooling liquid exhaust output and a paired supply liquid cooling input directing cooling liquid flow through one or more cold plate assembly positioned within the corresponding information processing system node to thermally cool the one or more heat-generating electronic components;
• and
• at least one manifold control unit integrated into one of the supply manifold and the return manifold and comprising:
• at least one communication interface module configured to communicatively couple the at least one manifold control unit to the supply control valve, and a datacenter control system;
• a memory having stored thereon rack temperature and liquid control (RTLC) code;
• and
• at least one processor communicatively coupled to the at least one communication interface module and the memory, and which processes instructions of the RTLC code to cause the at least one manifold control unit, while the supply and return manifolds are connected to a rack of information processing systems in a data center, to:
• receive node-level liquid telemetry data originating from one or more liquid telemetry sensors integrated at a respective node;
• trigger an amount of actuation of the supply control valve to control a rate of cooling liquid flow into the supply manifold, in part based on the node-level liquid telemetry data;
• and
• communicate rack level information with the datacenter control system.
