Google Server Secrets

Google this time give you a little secret about the server and its data center to CNET, of course we want to know what makes google the technology used is different, so you can find living with a very very short time this course is determined by how sophisticated the data setting center owned by google.

Most large companies always buy products from such servers from Dell, Hewlett-Packard, IBM, or Sun Microsystems. But not for Google, which incidentally have hundreds or even thousands of servers running on each core, had to google servers to their own designs. Project was initiated by Ben at Jai, who has been designing / assembling various types of Google's servers, and finally create a Google server that is more modern than other server system that makes everyone was amazed to see it.

What is interesting on a server that is used on the google server?
Battery on each server

Each Google server each have a 12-volt battery to supply power to the center in case of electrical problems. Google has been using this technology since 2005, data center has been designed in such a way that the size of a container in which there are 1.160 server, for power consumption, can reach 250 kilowatts.

Google apparently has long focused on energy efficiency that they now give a little glimpse of their experiences. Along with the recession lead to lower budget google operation, plus the issue of environmental and energy prices continue to rise makes Google should turn into efficiency evangelism, said Urs Hoelzle, Google's vice president of the division operation.

Due to this google should focus their data centers to be more efficient in terms of dealing with the distribution of energy / power, cooling, and make sure everything is running correctly and efficiently said Chris Malone, who was involved in data center design and efficiency measurement. Google data center has now reached an efficient level of the Environmental Protection Agency until 2011 menggunaakn course with more advanced technology.

Why use a battery?

Data-center which has been highly dependent on the UPS is large, centralized, it can be said to require a giant battery that must be alive when power interruption occurs before the generator takes the time to live. By constructing a special power supply into the server will be cheaper than the cost it was only calculated from the number of servers owned.

"Of course it would be cheaper than using UPS which tersental" and also "no disposal capacity."

Due to the google efficiency is a financial factor. Giant UPS is able to achieve 92 to 95% efficient, while the server-mounted batteries do it better, because they can measure the actual energy use with efficiency of 99.9%. "

The Google server was designed with a thickness of 3.5 inch 2U, or 2 rack units. Each server uses 2 processor, 2 hard drives, and eight memory slots mounted on a motherboard that was designed by Gigabyte. Google uses x86 processors from both AMD and Intel, Google also uses the battery design for its network equipment they are.

Power Supply and Battery

Advanced Power Supply

One form of Google's obsession with efficiency is the design of their power supply. Power supply current as ever to convert AC (alternating current-electricity from the building) to DC (direct-current from the battery), and the power supply usually has a 5-volt and 12-volt DC power. But for them to Google's designs supply only degan power 12-volt power, while the conversion process is done from the features of the motherboard.

This caused Google to add a surcharge of $ 1 or $ 2 for designing the motherboard, but this will treat price cheap power supply, so the power supply will only be in designs using the highest capacity. Google even pay attention to the better efficiency if trasmit to electrical energy through the copper wires at 12 volts compared to 5 volts.
Container for data center

Most people buying a computer server at the time they need it, but Google thinks are more different, especially in terms of scale. Jimmy Clidaras found that the efficiency of the basic needs of the google data center in a shipping container komposisikan size standard 1AAA, 1.160 inside the server, in which there are multiple containers in a data center.

Modular data center is not unique to Google; Sun Microsystems and Rackable Systems. But Google has started using them in 2005.
