Walk into Facebook data center to see Green computing Grace

Http://www.aliyun.com/zixun/aggregation/1560.html ">facebook in the North Carolina Forest Town (Dara City) has a huge data center, Its energy-saving design is today's high-power server group in the world of a beacon. Facebook officials have been visiting the data center with media personnel to show the charm of green computing. Facebook officials say the data center's measures have saved companies more than $1 billion trillion.

Data Center location without Avantgarde

Like many Silicon Valley companies, Facebook is famous for its office environment and Welfare. But remote forest-town data centers have an average of only 80 employees, who optimize the environment to make room for fun-flying saucer golf (Frisbee golf). It also offers a famous electric car. The Flying saucer Golf course overlooking the South Mountain range (South Mountains) spans 160 acres and has a pleasant journey to any station that an electric car wants.

Cold knowledge: The data center of the Forest Town was formerly a toxic textile factory and later became a shipyard.

Air Recycling Priority

Keven McCammon is the property manager of the data center. He described in detail the various air circulation facilities used throughout the building. 100% of the air used for heating and cooling is used outdoors. From the white jar beside him and the shutters near it, a row after row of air filtration, cooling and clean high-tech equipment abound. Even beneath the humble floor beneath his feet was a gas chamber filled with hot air, and the air of the chamber was used for recycling-a key to the entire facility against the super humid summers of North Carolina. During the winter, these hot air is used to provide heating to the district, but in the summer, hot air is used to eliminate damp, dry air for the server area.

The air is very powerful by pressure.

The flow of air throughout the data center is entirely pressure-pumped. Although it is not seen from the photo, the air is drifting from side to side with no small suction. This area has the obvious pressure, each corridor entrance has the double door small room, the function is the stabilizing pressure. The air is eventually pushed down from one axis to the server lobby, then blown over electronic devices to cool the electronics. The air is then transported to the hot passage, which is eventually pushed into the gas chamber, where it is recycled or sent back.

Repeat water

None of the cooling systems in the datacenter is customized, including the munters mesh in the figure. Munters mesh uses water to regulate temperature and make the air fresh. The Munters mesh system produces an atmosphere of optimum temperature and humidity combinations-and uses 80% less energy than conventional cooling methods. McCammon said that because of the use of the munters mesh system, they do not need to use reverse osmosis, but also reduce the use of water, because the water collected from the munters mesh system has been repeatedly used.

Redundant systems

Facebook often feels that it has broken the classic data center design theory and its design is highly redundant. The power system in the Facebook data center is a bit like a cooling fan, and another fan opens when a fan is broken. The power system in the data center facility has a back-up mechanism to switch between the primary and standby power supplies. Previous data centers must switch between power supplies by switching generators.

The community can accelerate the pace of innovation

The Open Computing database server, shown in the figure, is one of the most recent open computing projects. The new design uses flash memory as storage, with a 40% efficiency advantage over previous database devices. The database server is fully solid and has no moving parts, resulting in faster response times and easier storage performance. Facebook officials say things built inside the company--and then build a community--make things better and faster.

High technology ignores vanity

The plates in the diagram that resemble the pizza box between the server trays are not used to heat the lunch-they are there to force the air to flow downward to cool the server. Traditional server towers usually have a plastic bezel in front of them, but the team found that without the plastic bezel there was no need to customize and deploy these things, and there was an added benefit that the rear fans would work less pressure (and thus obviously save more energy). Facebook tells you that the look is secondary to relative utility and efficiency.

Data analysis can affect design

Facebook officials say the refrigeration facilities in the picture are redundant redundancy. By parsing user data, Facebook realized that 82% of the traffic was on a 8% photo base-so the old photos that were not used very often were put here and the servers were not too active and consumed less power. Facebook officials point out that, after doing so, the server is twice times more efficient and the data Center building is five times times more efficient.

Focus on growth when planning (especially for Facebook)

Facebook expects a growing demand for cold storage. Facebook reserved space for this. The refrigerated facilities in the forest town are of the letter e, and so far only one leg of the letter E has been used, and it is not functioning at full capacity. But Facebook's social network has 400 billion photos, adding more than 350 million a day, and there is no shortage of storage needed for this digital loft space.
