8 methods to strengthen energy saving and consumption reduction in data center

&http://www.aliyun.com/zixun/aggregation/37954.html ">nbsp; Energy saving, reducing carbon emissions, both for society and enterprise users have very important economic value and environmental significance. In the IT environment, especially for data centers with a large number of server storage devices, the topic of energy saving and emission reduction is being valued by more and more CIOs. In the face of 2008, if you want to do something about energy saving and emission reduction, I hope that the following 8 methods for your reference. Some of these methods are technical and some are management process level.

1) Strengthen equipment maintenance

Strict equipment maintenance Management is a more basic but also very effective way. Data center managers can improve the efficiency of the equipment through fine maintenance, ensure that all devices are running at the highest efficiency level, and modify the layout and configuration of various IT equipment to achieve the goal of reducing the heat dissipation requirements. These seemingly normal practices will improve the overall efficiency of the data center and reduce carbon emissions.

2 Virtualization

Believe that many users of the server application mode is still the traditional "one application to occupy a single server." In fact, you can run multiple applications securely on a single server using server virtualization technology. Also, virtualization can increase the average server utilization from 15–20% to IS, which means you can do more with fewer servers, and power consumption will not increase.

3 using more high-density multi-core CPUs

With a lower power requirement, the use of a new multi-core CPU can bring significant benefits. Imagine that if you were to integrate 8, 16, 24, or more processor cores on a single chip, the server would have a much higher performance per unit area, with a significantly reduced power consumption. In fact, over the past few years, technological advances have brought better performance per watt and performance per square foot for data centers. For example, in 2002 in order to achieve the performance of 3.7 Tflops, 25 cabinets, 512 servers, 1000 square feet, 128KW of electricity, and by 2007, the same 3.7Tflops performance, only a cabinet, 53 blades, covering only 40 square feet, Energy consumption is only 21KW.

4 Shut down unused servers

The simplest way to save energy is to turn off the unused power. Of course, the idea is naïve for those 7*24 hours of non-stop business. But in fact, some applications are not all-weather. Therefore, for these applications, the server and disk devices are turned on only when they are really needed. Of course, this requires a precise operational management process to ensure that IT services are delivered in a timely manner when business requirements increase.
