Improving HPC Cluster Efficiency with 480V Power Supplies
Release Date:May 22, 2013
Many of the servers used in computers on the HPC TOP500® list use 208Vpower supplies and very inefficient air cooling solutions. Some of these systems have tens of thousands of servers. This represents millions of dollars in wasted electric power and added equipment infrastructure costs. In today’s energy sensitive environment, these practices need to change. The switch to 480/277V power supplies for the next generation of high performance clusters is a small change with large rewards. Cray offers 480V power supplies with the Cray CS300™ cluster supercomputer series. This feature has been driven by requirements from customers such as U.S. national labs and the U.S. Department of Defense for more efficient power supplies and power distribution systems.
