Secret Google server design: with battery back-up power to do
As the world's biggest search engine, Google has a has a large number of large-scale server systems, but they know little about the outside world. Wednesday, the first time Google has designed its server mystery.
Most enterprises are from Dell, HP, IBM or Sun server systems purchase, and Google's server system is designed. Google servers are the most surprising, each server is equipped with 12V battery backup. When the main power when the accident happened, the battery can continue to supply.
Typically, the use of large-scale data center uninterruptible power supply (hereinafter referred to as "UPS") as a standby power supply, and the Google server is used 12V battery. In this connection, Zhai said: "Compared with the UPS, battery cost more low. "
Moreover, the battery more efficient than UPS. Typically, there is a large-scale UPS efficiency 92-95%, which means that part of energy being wasted, and the battery has 99.9 percent efficiency.
The efficiency of energy use (hereinafter referred to as "PUE") is a measure of energy-efficient data center is an important criterion, one on behalf of all values for all the energy used in equipment, but not used in cooling or power supply system; If it is 1.5, means that 50% of the energy spent by the latter.
The third quarter of 2008, Google data center PUE value is 1.21, already very low, but then fell to 1.20 in the fourth quarter, then dropped to 1.19.
Google has always attached importance to energy saving, energy saving and are willing to share the experience. Google vice president of operations (Urs Hoelzle) said that with heightened awareness of environmental protection, energy prices, as well as the economic downturn led to reduction of operating enterprises costs, Google is now sharing a good time for energy-saving experience.
In addition, starting in 2005, Google's data center on the use of a standard container design: Each container has a 1160 server, power consumption is 250 kilowatts, and each data center with multiple containers.
Google's servers thickness of 3.5 inches, is equipped with two processors, two hard drives, the eight memory slots have the Gigabyte motherboard. Google designers of the core server Zhai (Ben Jai) said the design of Google servers began in 2005, now has entered the sixth generation and the seventh generation.
Google operators of this size is bound to challenge many large enterprises, but at the same time there is no lack of beneficial side. For example, the results of a field of R & D can also be applied to many other basic structure, thereby speeding up the rate of return on investment. - 18418
