Inadequate Rack Airflow Supply Reference: Opengate-ASHRAE presentation, January 2009 1990’s RACK SIDE VIEW Today’s RACK SIDE VIEW ~ 300 CFM Airflow Consumed 800+ CFM Airflow Consumed ? ? Inadequate airflow volume at the face of the rack IT equipment will pull air from the space in front of the rack

Lack of Stability, Efficiency and IT Flexibility Floor Tile Gymnastics & CFD Modeling Reference: ASHRAE Journal Article – Designing Better Data Centers, December 2007 EPA-Uptime Institute conference material Mixing of hot exhaust with cold supply air causes hot spots On average, only 40% of available cooling is utilized due to bypass and over-provisioning to eliminate hot spots Typically, air is supplied well below ASHRAE standards in attempt to control temperature Despite this gross over-supply (2.5x), 10% of racks still experience hot spots Cooling capacity and rack heat density is not the problem…

Mixing of hot exhaust with cold supply air causes hot spots

On average, only 40% of available cooling is utilized due to bypass and over-provisioning to eliminate hot spots

Typically, air is supplied well below ASHRAE standards in attempt to control temperature

Despite this gross over-supply (2.5x), 10% of racks still experience hot spots

Small Space Cooling Use Building Cooling for Light Enclosure Loads Building Supply with Ceiling Plenum Return Heated exhaust air from IT racks are directed to a ceiling plenum that is the building air return. Air enters small space through a vent located low in the wall or door. Check local fire codes for acceptance. Building Supply with Dedicated Exhaust Duct Return to Corridor Heated exhaust air from IT racks are directed to a dedicated exhaust duct and air is directed to the corridor for building air return. Air enters small space through a vent located low in the wall or door. Check local fire codes for acceptance.
