Efficient data center design using novel modular DC UPS, server power supply with DC voltage and modular CDU cooling

An efficient cost effective novel modular scalable Data Center topology using Direct Current Uninterruptible Power Supply (DC UPS), server power supply with DC input and Cooling Distribution Unit (CDU) for IT load incorporating hybrid (both AC and DC voltage) distribution has been proposed in this paper. There is mismatch of infrastructure (both mechanical and electrical) capability and IT load in the existing Data Center. It takes years to reach equilibrium when IT load is balanced with infrastructure load capabilities. Major energy efficiency improvements and technological innovation of the Data Center industry had not been achieved for both electrical and mechanical infrastructure in the past, even as computing hardware and software follow Moore's law and has become efficient. A detailed analysis of the topology is presented to validate effectiveness of the proposed topology. Efficiency improvement and cost reduction of the proposed Data Center topology is found to be quite significant.
