Abstract

Part 1 - Case Studies on Two Co-location Data Centers (No. 16 and 17): Data Centers #16 and #17 were located in a four-story building in San Francisco, California. The data center building had a total floor area of approximately 97,900 ft2 with 2-foot raised-floors in the data services area. Two out of eight data centers in the building were occupied by computers and equipment, and were in operation at the time of the study conducted between October 15 and October 22, 2004.

Part 2 - Case Studies on Two Co-location Network Data Centers (No. 18 and 19): Two data centers in this study were within a co-location facility located on the sixth floor of a multi-story building in downtown Los Angeles, California. The facility had 37,758 gross square feet floor area with 2-foot raised-floors in the data services area. The two data centers were designated as the west data center (DC #18) and the east data center (DC #19).

Part 3 - Case Study on an IT Equipment-testing Center (No. 20): The data center in this study had a total floor area of 3,024 square feet (ft2) with one-foot raised-floors. It was a rack lab with 147 racks, and was located in a 96,000 ft2 multi-story office building in San Jose, California. Since the data center was used only for testing equipment, it was not configured as a critical facility in terms of electrical and cooling supply. It did not have a dedicated chiller system but was served by the main building chiller plant and make-up air system. Additionally it was served by only a single electrical supply with no provision for backup power in the event of a power outage. The Data Center operated on a 24 hour per day, year-round cycle, and users had full-hour access to the data center facility.

Part 4 - Case Study on Computer-testing Center (No. 21):The data center in this study had a total floor area of 8,580 square feet (ft2) with one-foot raised-floors. It was a rack lab with 440 racks, and was located in a 208,240 ft2 multi-story office building in San Jose, California. Since the data center was used only for testing equipment, it was not configured as a critical facility in terms of electrical and cooling supply. It did not have a dedicated chiller system but served by the main building chiller plant and make-up air system. Additionally, it was served by a single electrical supply with no provision for backup power. The data center operated on a 24 hour per day, year-round cycle, and users had all hour full access to the data center facility.

Part 5 - Case Study on a Corporate Data Center (No. 22): The data center in this study had a total floor area of 10,000 square feet (ft2) with one-foot raised-floors. The data center housed 377 computer racks, and was located in a 110,000-ft2 office building in Pasadena, California. However, the raised-floor was not utilized for cold air distribution. Communications and power wiring and fire sprinkler were located within the space above the ceiling. There were two standby generators, each rated at 1500 kW/kVA providing backup power supporting all building loads.
