The data center in this study had a total floor area of 8,580 square feet (ft(sup 2)) with one-foot raised-floors. It was a rack lab with 440 racks, and was located in a 208,240 ft(sup 2) 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.
