Google has recently lifted the secret veil on their server technology. Google servers are some of the fastest and the most dynamic machines known built with a very organized infrastructure.

They are not directly connected to the clients across the world but through subnets and other server machines. A machine called a load balancer is employed, which sends the clients requests to the servers after it passes the proxy servers.

Such proxy servers also called squid servers in turn send the results to the web server of Google, which coordinates the query execution into an HTML page. Web spidering is employed using data-gathering servers to gather data from the sites on the Web, wherein GoogleBot, which runs on algorithms, is used, for web search.

The servers are maintained with care and security at all times. The specifications of the modern Google servers were classified, as such details were considered sensitive and nontransparent.

However, recent news released conveys that Google servers are X86 PCs which run on Linux operating systems. The power specification is drastically increased to 20 megawatts of power for over 450 thousand servers.

Google servers are huge, vulnerable to faults and failures, and very expensive to maintain the whole system infrastructure unit by unit. Each container that is as big as a shipping container consumes up to 250W with around 1160 servers concisely packed and maintained.

Every server in the container is connected to an independent battery. Google also got the patent for such a built in battery design. The cooling system of these containers is used to keep the temperature low, even though it consumes a lot of power, it is not a factor that can be compromised on.

The efficiency is around 95 percent and is designed with two U racks each with a switch and 8 DIMM memory slots. Each rack consists of around 20 to 40 servers, 1U and the switches in turn connected to two gigabyte switches. These servers run on Nucono P4 processors on a dual Xeon board with a 604-socket. It possesses a combination of AMD and Intel hardware implying increased performance.

Google keeps enhancing their power-efficient servers, which run partly on Intel hardware that consumes the majority of the power.
