Energy efficiency is sometimes not considered an aspect of energy proportionality, but it should be. To understand why, consider the analogy of commuting to work—alone—in either a pickup truck or compact car. The far superior gas mileage of the compact car results in a more “energy proportional” commute, and this same thinking should apply to servers.
To promote the use of energy-efficient systems in data centers, the U.S. Environmental Protection Agency created an ENERGY STAR rating for servers and other IT equipment. This is a step in the right direction, but the rating has only limited value. The reason is: an ENERGY STAR rating is given to the 25 percent most efficient servers from B2B Email List a specific vendor, so depending on the servers tested, the manufacturer can influence which models get rated. Furthermore, the rating does not factor in the age of the equipment nor does it show the year of measurement. With an average of two-times improvement in server performance every two years, this is a serious shortcoming.
A far better measure of energy efficiency for servers is transactions per second per Watt (TPS/Watt), and this metric is available using the standard power measurement procedure (UL2640) from Underwriters Laboratories. UL2640 utilizes the PAR4 Efficiency Rating system to determine TPS/Watt and other useful metrics, such as idle power consumption under no load. These metrics enable IT managers to compare the transactional efficiency of legacy servers with newer ones, and newer models of servers with one another. And a best practice today is to assess energy efficiency during every hardware refresh cycle and whenever adding capacity. In addition, PAR4 publishes idle and peak power consumption, which is essential to optimize the utilization of available power in each rack.
Twelve out of 63 electrical products were out of compliance with the Restriction of Hazardous Substances (RoHS) directive, in tests by Sweden’s Chemicals Agency, Kemi, and the country’s Electrical Safety Authority. The agencies found excessive lead in 11 products, and prohibited levels of polybrominated diphenyl ether flame retardants in one product. The bodies passed details of seven companies to Swedish prosecutors.
Monadnock Paper Mills‘ Bennington, NH, facility has achieved recertification for compliance with ISO 14001 for environmental management systems, following an audit by Systems and Services Certification, a member of the SGS Group. Over the past three years, Monadnock has realized a 14 percent reduction in water consumption and a 7 percent reduction in electricity use, the paper company said.
An ASTM task group has sent the EPA proposed revisions to ASTM E1527, the standard for Phase I environmental site assessments (ESAs), Winston & Strawn LLP said. Lenders and investors in commercial real estate transactions often require the standard. The new standard will need EPA approval to meet the agency’s requirements of All Appropriate Inquiry to receive liability protections under CERCLA, commonly known as Superfund.
