When Mr. John Glass, P.E. (Jack) became the critical systems director of Citicorp’s main data processing facility, he inherited an ailing building with an alarming lack of infrastructure stability.
Previous efforts to patch the aging systems had merely aggravated the situation. State-of-the-art technology was supported by fifteen-year old roofing and mechanical-electrical (ME) infrastructure. Systems needed to be redesigned to provide concurrent maintenance capabilities, fault tolerance, additional capacity, and energy efficiency.
Built in 1986, this 745,000-sq-ft facility houses trading operations for 2,400 stock traders, supporting global financial trading, corporate accounting, network services, and telecommunications. Base infrastructure includes 10,000 kVA of UPS power; 14 MW of engine generator; 4,000 tons of chillers; 5,000 tons of cooling towers; and 14.8 kVA of medium-voltage utility power. Over 60,000 sq ft of raised floor data center is required to support processing operations. At the design goal of 50 W/sq ft, over 3 MW of UPS power will be required to support data, telecommunications, and trading floor operations.
