of the fan as compared to the electrical power required to run the fan. The M1000e fan operates at

extreme efficiencies which correlates directly into savings in the customer's required power‐to‐cool.

The high‐efficiency design philosophy also extends into the layout of the subsystems within the

M1000e. The Server Modules, I/O Modules, and Power Supplies are incorporated into the system with

independent airflow paths. This isolates these components from pre‐heated air, reducing the

required airflow consumptions of each module.

Figure 25. Server Cooling Air Profile

The Server Modules are cooled with traditional front‐to‐back cooling. As shown in the figure, the

front of the system is dominated by inlet area for the individual server modules. The air passes

through the server modules, through venting holes in the midplane, and is then drawn into the fans

which exhaust the air from the chassis. There are plenums both upstream of the midplane, between

the midplane and the blades, and downstream of the midplane, between the midplane and the fans,

to more evenly distribute the cooling potential from the three columns of fans across the server

modules.
