Abstract
A manifold for cooling electronic equipment, the manifold including a facility side coolant supply line, a facility side coolant return line, liquid-to-liquid heat exchangers, and pumps. The liquid-to-liquid heat exchangers are connected in parallel to the facility side coolant supply line. Each of the pumps is coupled to a liquid-to-liquid heat exchanger and regulates coolant flow through the coupled liquid-to-liquid heat exchangers.

A method of liquid cooling using a manifold:
- detecting that a server on a server rack is connected to the manifold;
- enabling liquid coolant to flow through a liquid-to-liquid heat exchanger connected to the server upon detecting that the server is connected to the manifold, wherein the liquid-to-liquid heat exchanger is one of a plurality of liquid-to-liquid heat exchangers connected in parallel at the manifold to a facility side coolant supply line;
- and
- activating a pump physically coupled to the liquid-to-liquid heat exchanger upon detecting that the server is connected to the manifold, the pump regulates coolant flow from the liquid-to-liquid heat exchanger to the server;
- detecting that the server on the server rack is disconnected from the manifold;
- identifying the liquid-to-liquid heat exchanger that has been disconnected from the server;
- and
- disabling coolant flow to the liquid-to-liquid heat exchanger that has been disconnected from the server by activating a valve diverting coolant flow from the liquid-to-liquid heat exchanger that has been disconnected from the server to one of a plurality of bypass lines within the manifold.
