Reduce power consumption in data center three steps away

Power efficiency will be a necessary part of future data centers. As many companies look for innovative ways to squeeze the last value out of existing resources, sensible dealers will be prepared to do so.

With a little bit of common sense and a few simple skills, dealers can not only http://www.aliyun.com/zixun/aggregation/17183.html "> Help customers reduce their monthly electricity bills, but they can also generate extra revenue for themselves in the process." Here is a simple plan.

Step one: Check it out.

The best plans are often the simplest; when you've finished reading this, you should have the principles of Checking Data center efficiency (and making it easy to earn some revenue).

Regardless of the size of a company's data center (or server cabinet), they all have one thing in common: they all contain equipment that will dissipate heat, and the heat emitted must be discharged. It's not hard to understand the benefits of efficient data centers because cold parts live longer, run faster, and operate more efficiently.

In addition to the computer room air conditioning (CRAC) system, the main factors affecting the cooling efficiency of the computer room are the relative inlet and outlet position of the computer equipment.

Therefore, the first thing to determine is whether the servers, switches, and other thermal devices emit hot air along the same general direction. This technique, which uses hot and cold passages, helps isolate the temperature of the air and ensures that the air entering the machine is as cold as possible;

Once the layout of the room inside the hot and cold channel, you can add partitions between those channels, and further improve efficiency, just like the car air-conditioning, it is best to roll up the window. In addition, the technology can be slightly changed, only to isolate the hot channel, the computer's exhaust port to the air inlet of the CRAC device, or to the ceiling of the inflatable room.

Step Two: Ascertain Pue

According to the Lawrence Berkeley National Laboratory Survey found that if the customer's data center has been fully isolated, can save air-conditioning cost of 15%, the cost of the fan system to save 67%.

The next step is to compute the power efficiency (PUE) of the data center. To conduct a comprehensive power review, this must be done first, as it provides a measurable benchmark for tracking improvements in power efficiency. As long as the total power consumption (watt) of the data center and its infrastructure (including lighting, cooling, and all IT equipment) is divided by the IT load itself, the Pue can be reached. It loads only include components that are directly related to your computer, such as servers, storage systems, switches, routers, and so on, and do not include uninterruptible power supplies (UPS), cooling systems, or any device that is not connected to your computer.

Compare the Pue of your business with the national average Pue (http://uptimeinstitute.com/) of uptime Cato. This number should be between 1.8 and 3.0.

The ideal pue should be 1.0, which indicates that the computer resources comprise the entire infrastructure. This is, of course, impossible in most cases; PUE 2.0 or 2.5 is considered to be the average of small and medium data centers. Google's Pue is 1.2, and Google runs the world's most efficient data center. The company has released its own set of electricity-saving methods (http://www.google.com/corporate/datacenter/best-practices.html). Google's ability to design and tailor all its servers has helped.

Step three: Comprehensive Power review

For ordinary users, the only way to do this is to measure the power consumption of hardware components in data center cabinets and racks. A quick way is to check the lifetime of the Uninterruptible Power Supply (UPS) system used by the customer. Today's ups are much more efficient than those made only three years ago. If they live longer than five years, they may be able to throw them into the rubbish heap.

The next step is to measure and record the power consumption of the remaining IT components. To simplify this task, we obtained the Power Audit (http://i.crn.com/misc/PowerAudit_sheet.xls) calculation form from appropedia.com, which contains a formula for calculating electricity consumption. Once the calculations have been completed, you can determine which parts are the least efficient, and then set their respective settings to reduce the amount of power consumed, or to change or upgrade to more energy-efficient models.
