Analysis of common methods of energy saving and consumption reduction in data center

Effective data center Energy saving can save 40% or more energy expenditure. Imagine a data center that consumes 10 times to 100 times times as much energy per square foot as an office building, and in some cases the highest energy consumption, or even 40% of the company's greenhouse gas emissions, is clear about how important it is for the data center to conserve power and reduce consumption.

Data center executives often do not have comprehensive management tools to monitor energy consumption. Therefore, the lack of the energy strategy of the system analysis to determine the data center energy-saving can bring great benefits is what or high-energy consumption will bring great risks to the operation of the enterprise. This also hinders the development of related processes and the deployment of strategies. Once you start to measure the energy consumption inside the datacenter, you can find the biggest source of energy consumption, develop plans to achieve your goals, and execute plans and documents related to the process.

The following are the most common ways to reduce energy consumption in data center http://www.aliyun.com/zixun/aggregation/14137.html "> Energy Management:

1. Look for devices that are idle, close them, or reassign tasks. At present, about 15% to 20% of all servers are never used. Idle servers consume about three-fourths of the energy consumed by servers with 100% utilization. However, most data centers do not have the tools to find unused devices. An effective energy management solution can help you find all of the servers that are idle or unused and use asset cost analysis to make judgments.

2. Virtualization. Only 35% of servers implemented virtualization in the data centers that claim to have completed the virtualization process deployment, according to a new market research. In other words, the research report reveals that finding servers for virtualization is still a cumbersome process. An energy management solution allows data center executives to clarify the cost of each asset and the utilization of the data center. Virtualization can then be targeted at low utilization or high energy consumption within the scope of the plan.

3. Storage consolidation. In the case of servers, some storage units have never been used. To improve the utilization of storage devices, you should identify repetitive data, old data, unused data, and inefficient alignment strategies. Once you have mastered the cost and energy of your storage device, you can make informed decisions about storage consolidation.

4. Asset reconfiguration. Since the focus on energy consumption has only recently prevailed, most it devices still do not have the concept of energy efficiency when configured. Sentilla, for example, reconfigured the file server to a low-power mode at night and weekend, saving about 33% of the energy and saving energy by changing the server's energy management settings to match the workload.

5. Finally, data center executives can postpone capital expenditure. Many data center executives worry about the capacity of their uninterruptible power system (UPS) and backup generators set. These power supplies require a significant amount of capital investment and necessary resources during installation (it may also disrupt IT services). Energy management tools can directly track the power supply requirements and capacity of uninterrupted electricity. Good tools can also continuously monitor the capacity of uninterruptible power supply, all of the information to the data center executives, let them to recycle those have been allocated but no use of energy, do a good job in the data center energy consumption.
