High Density Data Center

Confidential Client
Hillsboro, Oregon, USA

We designed this high-performance data center to house high-density computer servers that generate heat loads in excess of 500 watts per SF, with individual cabinet loads of up to 22 kilowatts. The initial phase of the two-story data center is comprised of identical independent server equipment room modules, each containing 240 cabinets, 3.1MW of IT power, and approximately 6,000 SF of area.

The facility is designed for five independent compute modules with two modules currently constructed and operating. Each two-story module was created to be independent and isolated for risk management, security, and fire protection reasons. The modules are organized along a central corridor/utility spine that extends the length of the building. This spine serves as the main circulation path for people and equipment along with being the main distribution corridor for the building's utilities. We plan that the future modules will "plug" into the central spine and be served by the modular chiller plant.

Cooling of the server cabinets within each module is provided by a single air conditioning system. Cool air is supplied to the lower level to cool the electrical distribution equipment and flows up through floor openings to the upper level where it enters the server room cold aisle through raised floor grating. The cool air is then drawn through the cabinets, providing the necessary cooling to the servers. The warm air exits the backside of the cabinets and enters the hot side where it is drawn through the open ceiling to the recirculation air handlers located in a mechanical chase. The air is then pushed down to the lower level, where it travels through fan coil cooling units and repeats the airflow process in less than a minute.
