Today’s networking OEMs face the challenging task of designing for seemingly opposite goals—high performance in an energy-conscious “green” environment.
The EPA estimates* that in 2006 the nation’s servers and data centers used about 1.5% of the total U.S. electricity consumption—a whopping 61 billion kilowatt hours (kWh)—at a cost of $4.5 billion. In 2011 these figures could nearly double, reaching more than 100 billion kWh, at a staggering annual cost of $7.4 billion.
As one of the fastest-growing energy-use sectors in the nation, servers and data storage centers need a memory solution that can satisfy their rigorous performance demands while delivering the potential for significant improvements in energy efficiency. We put together these comparison charts to show how today’s leading memory technologies stack up in terms of bandwidth per watt:
