Protocol for communication between a plurality of liquid cooling modules for computer servers

A method of communicating between a plurality of liquid cooling modules of a cooling system for one or more computer servers, each liquid cooling module comprising an outer housing surrounding a primary hydraulic circuit configured to contain a first liquid coolant, a secondary hydraulic circuit configured to contain a second liquid coolant, a heat exchanger capable of exchanging heat between the first and second liquid coolants, and a control circuit board, the method comprising:

• communicating, by the liquid cooling modules with each other in a manner that operates in N+1 redundancy with a collaborative protocol without a master/slave relationship, where N is greater than or equal to 2, to enable a standard replacement of any one of the plurality of liquid cooling modules without stopping cooling and without stopping an operation of the one or more computer servers;
• and
• before switching from an active mode in which cooling is performed to a backup mode in which cooling is no longer performed, a redundant liquid cooling module of the plurality of liquid cooling modules verifies beforehand that a data set is consistent across all of the plurality of liquid cooling modules and that the consistent data set is maintained for a predetermined amount of time, by using a consistency indicator enabling to verify that the synchronization between all the cooling modules has been achieved.
