“Jeff Dean, a Google Fellow who has been with the
company since 1999, gave a speech at the Web Search and Data Mining
meeting in 2009 where he unveiled how Google puts together its data
centers (PDF). Because the meeting was in Barcelona, Spain, his
speech didn’t receive the attention it deserved in the United
States.“After all, wouldn’t you like to know how Google manages to do
what it does? And how the company’s experience and expertise can
help you predict how your data center measures up?“A Google data center starts with high-speed, multi-core CPUs,
Dean revealed. Each of these servers has 16GBs of RAM with fast 2TB
(Terabyte) hard drives. These are kept in racks of 80 servers tied
together with 10Gb Ethernet or other high-speed network
fabrics.”
