For instance, power supply firm Advanced Energy welcomed the inclusion of 48V power shelves: "Traditionally, data center racks have used 12V power shelves, but higher performance compute and storage platforms demand more power, which results in very high current.
Unlike the traditional 12 V DC power distribution historically utilized in data centers, 48V systems reduce currents and minimize resistive losses throughout the rack. More efficient architectures also require less overall wiring, enabling data center operators to save on traditionally significant copper costs.
In 2016, Google introduced a 48V rack power architecture designed to replace traditional 12V systems, marking a major shift in datacenter design. Google's 48V system was developed to meet the power demands of modern high-performance computing, particularly in applications requiring GPUs and other power-hungry accelerators.
A primary advantage of implementing 48 V rack power architectures is the improved energy efficiency they provide. Unlike the traditional 12 V DC power distribution historically utilized in data centers, 48V systems reduce currents and minimize resistive losses throughout the rack.
