Cloud Data Center Pue: 1 sprint not a dream?

In an article that describes how intel it is doing cloud computing practices, how the department uses its own http://www.aliyun.com/zixun/aggregation/13883.html "> Virtualization technology May impress , but by contrast, the department's Shanghai data Center has achieved 1.3 on the PUE value of the data center (i.e., the ratio of total power consumption to the power consumption of IT devices, the number closer to 1). Believe that many users want to launch cloud computing, but also worry about data center power control problems, are very keen to get the secret behind this number.

In fact, the PUE value of 1.3, for many data centers has been difficult, but it is far from the highest level, for example, Yahoo called "Computing Hut" (Yahoo! Computing Coop) The Pue value of the datacenter is only 1.08, which is closer to the ideal digital--1, but how does it work?

In fact, in Yahoo this data center promotes the energy efficiency, in the process of energy saving, the most significant role is a technology called HTA (High ambient temperature) data center, it is the essence of the data center is to upgrade the ambient temperature, even to do not often or no longer need air-conditioning refrigeration, Without air-conditioning, a non-it power consumer, Pue's ascension will naturally be obvious.

However, increasing the ambient temperature in the data center and even stopping the air conditioner it devices in the data center will not overheat and downtime, in this respect, we should not worry too much, because: first, water cooling or natural wind cold way, can also be the data center of the ambient temperature control within a safe range, and, secondly, It can be achieved through advanced chip-level, system-level, rack-level and data-center-level energy-saving or efficiency-enhancing technology to achieve the high environmental temperature of IT equipment stable operation.

Who can provide this kind of in-depth detail with a holistic approach? Intel Corporation can and will be the leader. Its related technology, each transistor within the processor in the IT device that is deployed from the data center to the processor and chip, to the chip package and heatsink, to the motherboard and system cooling, then to the power of IT equipment, to the rack, and finally to the entire data center facility, even to the grid and power distribution, Each level of power can be achieved to save the province!

This layered, progressive energy-saving strategy, the realization of the high degree of difficulty imaginable. After all, few companies have been able to fully cover these links in their previous perceptions. But today, at a time when cloud computing is sweeping the globe, to help corporate users build an energy-efficient cloud computing infrastructure, Intel has built a range of energy-saving technologies to achieve these goals, starting with the technology it specializes in.

Intel's energy-saving "stunts" include: second-generation high K-gate dielectric + metal gate transistor technology and 32-nanometer chip fabrication process for energy-efficient transistors are the cornerstone of the high energy efficiency performance of the Intel processor platform; Intelligent energy-saving technology is used on processors and other chips to automatically save energy according to changes in workload; The use of copper heatsink on the chip heat dissipation can be more efficient to emit the heat generated by the chip; customized fan technology for internal cooling of the equipment can adjust the speed according to the temperature change to save electricity; intel on demand redundant power technology for powering the IT device Allows users to avoid the need to install a large ups, to reduce the power consumption of UPS; For server board level, line level, rack level, and facility level Intel Smart Power Node manager and data Center Manager can monitor and adjust individual IT equipment, row level and rack level separately. In order to try to use each of its power consumption for data calculation and processing, rather than waste in the system idling, but also to optimize power grids and distribution of Intel Smart grid embedded technology and the Intel Open Energy Agreement, support the optimal way to transfer power from the power station to the data center.

What effect does it have to wield the energy-saving combination of Intel? Data from real-world applications is the best proof: with Intel Smart Power Node Manager as an example, Yahoo's data center found it for power and thermal monitoring, replacing IP power boards and serial sets, saving about 400 dollars per rack; BMW's data show that it can increase its server deployment density without increasing the power of the racks, increasing the performance of each rack by 40%; The Node Manager white paper of Baidu and China Telecom confirms that it can achieve up to 30% power optimizations without impacting performance.

In view of this, the technology is a smooth implementation of the high Temperature Environment data center essential to help, in fact, Intel is one of the most powerful agents of the high temperature data center, it is today with the Green Grid Alliance, the European Union and the United States, the Institute of Heating, Refrigeration and air-conditioning engineers and other industries In order to establish a high temperature data center specification, the goal is to allow those who enjoy air-conditioning cold air, in the 18°c~21°c ambient temperature of IT equipment can be stable operation at a high ambient temperature, so that less use even without air-conditioning.

In addition to its normative efforts, Intel has begun a related attempt with some of the leading internet companies, including Yahoo, mentioned above: Intel is located in New Mexico State, with 900 production servers, the concept of Proof of CONCEPT Data Center is implemented under 33°c 100% Air exchange to dissipate heat, resulting in a savings of about 67% of the power consumption, equivalent to a 10 MW data center can save 2.87 million dollars; Facebook has also tried to run its data center in Santa Clara, Calif., under 27°C, reducing its annual energy spending by $229,000 trillion. These attempts have proved that, with the support of various advanced energy-saving technologies, the PUE value of the cloud-era data center to 1 sprint is not an unreachable dream.
