Comment on the products of 4 major server manufacturers from energy saving

Today, http://www.aliyun.com/zixun/aggregation/13597.html "> Enterprise IT Infrastructure is more focused on energy consumption and environmental issues." "When we are ready to use the new server, we choose the standard: Each kilowatt-hour of the product and the best computing performance the computer can achieve." "820.html" >steve Hilton said he was managing director of Wall Street Credit Suisse and head of the Enterprise server and Storage department.





in the past few years, chip, server manufacturers have each introduced a method of energy saving, four server manufacturers--hp, IBM, Sun and Dell claimed that their products can operate at a lower temperature. Here are the so-called "cool" products from four server manufacturers:




The
Dell:dell a large production of PowerEdge rack servers, claiming a 20% reduction in power consumption than standard versions. The smart Energy version of Dell 1950 and 2950 brings performance improvements per watt 25%. Dell's Optiplex Desktop product line has also been planned to apply this energy-saving technology. In addition, Dell provides the data center capacity Scheduler (Datacenter Capacity Planner) that can be downloaded. ）





Hp:hp suddenly turned to the blade server because it provides better high-density integration, better power and cooling, and improved virtualization technology. HP's BladeSystem C class, released last June, has a good energy-consumption ratio, and HP says it can increase energy efficiency by 32% compared with traditional rack servers.





HP's static and dynamic intelligent cooling (dynamic and static smart cooling) uses model technology to simulate the flow of air in the data center, while providing a water-cooled technology exchanger, which is fixed on the side of a standard 19-inch rack, with a chilled water cooling system provided under the floor.





IBM:IBM's coolblue tries to build a full solution that starts with a data center assessment, through budgeting, planning, and obsolescence. CoolBlue Power executive allows customers to collect, apply and control their electrical applications.





IBM also offers a backdoor heat exchanger, a water-cooled closed-door closure that takes about 55% of the rack's back heat and converts it into cold air.





Sun:sun says its T1000 and T2000 servers consume just as much as a light bulb. These servers, with Sun's coolthreads multithreading technology (which provides technology to run 32 threads at a time on a 8-core processor), consumes about one-third of the energy compared to a X86 computer, and only half of the data center space compared to other servers, At the same time provide twice times the performance.





Sun's SOLARIS10 operating system includes "container" quasi virtualization technology that can increase the utilization of SOLARIS10 servers (true virtualization software should be cross-platform).
