1. An apparatus for minimizing a volume of coolant leaked in liquid cooled electronic equipment, comprising:

  • a server rack housing a plurality of servers configured to receive facility side coolant;

    a plurality of closed liquid cooling loops in the server rack, each of the closed liquid cooling loops coupled to at least one of the servers in the server rack, each of the closed liquid cooling loops restricting coolant flow entirely within the server rack;

    a plurality of catch basins in the server rack, each of the catch basins being positioned between the servers in the server rack, each of the catch basins configured to collect leaked coolant from a respective one of the plurality of closed liquid cooling loops;

    a plurality of basin leak detectors, each basin leak detector from the plurality of basin leak detectors positioned at a respective one of the plurality of catch basins and configured to detect the leaked coolant from the respective one of the plurality of closed liquid cooling loops;

    a plurality of liquid to liquid heat exchangers in the server rack, each of the liquid to liquid heat exchangers coupled to one of the closed liquid cooling loops in the server rack and configured to transfer heat from the closed liquid cooling loops to the facility side coolant;

    a plurality of pumps, each of the pumps positioned above the respective one of the plurality of catch basins and circulating a coolant inside the respective one of the plurality of closed liquid cooling loops, each of the pumps configured to power off in response to a respective one of the basin leak detectors positioned at a respective one of the plurality of catch basins detecting the leaked coolant from the respective one of the plurality of closed liquid cooling loops;

    a controller to power off a respective pump connected to the respective one of the plurality of closed liquid cooling loops with the leaked coolant from the respective one of the plurality of closed liquid cooling loops in response to detecting the leaked coolant by the respective one of the basin leak detectors; and

    a plurality of bypass valves configured to disengage a respective one of the plurality of liquid to liquid heat exchangers from the facility side coolant in response to detecting the leaked coolant from one of the plurality of closed liquid cooling loops.
