Aisle clearances

Cold aisle clearance

The maximum protrusion of any installed IT component directly impacts the available cold aisle clearance for removal and replacement of other IT components. Maximum component depth must follow the clear aisle distance calculations. The following figure shows how to calculate this distance.

The maximum rack face-to-cold aisle wall distance is 39.5 inches. In the figure, X represents any protrusion into the cold aisle starting from the rack face of the installed IT component (for example, the bezel). Y represents cold aisle clearance. The cold aisle clearance dictates the maximum depth (D) of any installed IT component. To find the maximum cold aisle clearance, calculate 100.33 cm (39.5 in) - X = Y.

IMPORTANT: As the value for X increases, the value for Y decreases, which also decreases the maximum depth allowed for an installed component.
