Until very recently, data center managers were only concerned about performance and acquisition costs when they were considering buying new servers or expanding their facilities. But soaring energy costs and system power consumption have forced data center managers to analyze all aspects of their electrical and thermal expenditures - including server memory modules - as these managers seek to save money, become more efficient, and act to conserve resources for future generations. Recognizing this challenge, Micron’s research and development engineers discovered a way to reduce power consumption in memory modules without affecting performance.
