Data center modules and method of large-scale deployment

A data center module, the module comprising an outer envelop and a plurality of levels, the plurality of levels being superimposed one over the other and comprising a bottom level and at least two upper levels, the at least two upper levels comprising a plurality of computing machines, the plurality of levels being in fluid communication thereby allowing downward and upward movements of air within the module, the module comprising an air handling unit, the air handling unit being in fluid communication with the top of the at least two upper levels, wherein

• a) each of the plurality of levels is partitioned into a first area and a second area;
• b) the first areas of the plurality of levels are in fluid communication to allow downward movements of air within the module, and wherein the second areas of the plurality of levels are in fluid communication to allow upward movements of air within the module;
• c) the first area and the second area of the bottom level are in fluid communication to allow air moving downwardly into the first area to transfer upwardly into the second area;
• d) the computing machines are located in one of said first area or said second area of each of the at least two upper levels;
• e) the computing machines are arranged in at least one row, and wherein the at least one row defines at least two aisles;
• f) the at least two aisles comprise at least one cold aisle located on one side of the at least one row of computing machines, the at least one cold aisle carrying cooling air toward the computing machines, and wherein the at least two aisles comprise at least one hot aisle located on the other side of the at least one row of computing machines, the hot aisle carrying warmed cooling air flowing out of the computing machines;
• g) the at least one hot aisle has non decreasing cross-sections from a lower level to a next upper level,
• wherein the air from the at least one hot aisle flows upwardly from one level to the next.
