THE DATA CENTER JOURNAL | 5 www.datacenterjournal.com PROJECT DESCRIPTION Data Center Expansion Southern California T he Data Center Expansion Project was the culmination of a multi-year master plan. e goal of the master plan was to implement improve- ments to allow for scalable expansion, increase availability, and, ulti- mately, provide flexibility for growth in a sometimes fickle Information Technology driven industry. e starting state was a 99.95% avail- ability design providing 608kW of redundant critical (UPS) power and 1.8MW of redundant standby emergency power generation capacity supported by a DX split system critical air conditioning system with N+1 redundancy. e end state planned and implemented over a five-year period resulted in scalable solution capable of 2,430kW of redundant critical (UPS) power and 4.25MW of redundant generator power. e construction was performed on a live data center while maintaining all critical systems availability throughout the dura- tion of construction. e master plan was forward thinking enough to include migration of the DX cooling system to an innovative first-of-its-kind evaporative assisted, air- cooled, magnetic bearing, chiller ("Multistack") based chilled water plant planned for 800tons redundant cooling capacity piped for two diverse pathways to each computer room air handling unit. e system selection was based on a complete total-cost-of-ownership model that was developed with the help of computer aided energy modeling soware. e evaporative cooling provided over 30% PUE improvement. e efficiencies gained by utilizing this unique cooling solution allowed for minimal upgrades to the existing utility infrastructure allowing shorter construction duration with the benefit of speed-to-market to the IT end user. In addition, the evaporative assist provides approximately 50% water consumption reduction over traditional water-cooled systems. From a reliability standpoint, the elimination of the dependence of water was also a key factor in the decision making process. e master plan has provisions to add a 2250kW to the newly installed generator plant. is will allow replacement of a 22+ years of age existing genera- tor plant with minimum impact and cost. In addition the expansion area has dedi- cated fire rated rooms for future redundant UPS and battery systems. With the advent of smart control systems, data centers are becoming increas- ingly complicated. A correctly designed control system can help minimize the opportunity for human error and significantly improve availability. However, con- trols if not implemented properly can be extremely costly. A hybrid Tridium/Aler- ton system with central plant optimization provided the perfect solution balancing the power of the Niagara Framework and the cost efficiency of a branded solution. e design team also incorporated key sustainable design components into every aspect of the design, from architectural, civil, mechanical, plumbing, and electrical systems. Sustainable features include centralized adiabatic humidity control, photovoltaic panels for support of administrative areas (isolated from critical systems), day lighting (via skylights), and a Jellyfish storm water treatment system to name a few. e total project was completed for just under $25,000,000 in construction cost.
