Green memories accelerate ROI for data centers

Sylvie Kadivar, director, DRAM strategic marketing, Samsung Semiconductor, Inc. | Feb. 15, 2011
Hundreds of thousands of KWh are being consumed by the use of memory components in servers today. By adopting more energy-efficient components in optimized server architectures, such as lower voltage DRAMs and advanced solid-state drives (SSDs), data centers can drastically reduce power consumption and associated energy costs.

Another measure of performance is the number of inputs and outputs per second per watt or IOPS/W. In this metric, the Green SSDs outperform the traditional 15K rpm HDDs by a huge margin. Internal tests demonstrate that second generation Green SSDs IOPS/W are 200 times higher than a 15K rpm HDD. In addition, the SSDs occupy considerably less space, and depending upon the application, a single Samsung SSD can replace between four and 40 15K rpm SAS HDDs in a server array.

Few will argue that quick payback for both Green DRAM and SSDs matters a great deal, and upon close examination, even fewer will argue about the overall cost-saving impact of Green DDR3 and Green SSDs in substantially shortening most data center's ROI.
