(New breakthroughs in source and cooling technology enable simple and rapid deployment of separate high-density zones within existing or new low-density data cores. These separate high-density areas ensure predictable and reliable operation of high-density equipment without any negative impact on the performance of existing low-density power and cooling infrastructure. An added bonus is that these high-density areas operate much more efficiently than conventional designs. This white paper also provides guidance on design, implementation, and predictable operations for high-density areas)
