If you’ve taken a look at our new site, Where the Internet lives, you’ve gotten an in-depth look at some of our infrastructure and the people who help keep Google up and running for you. Our data center infrastructure is the foundation for all Google services, powering our servers, networking equipment and cooling systems.
Our emphasis on cooling systems might come as a surprise, until you consider how warm a personal computer can become during use. Data centers, which house thousands of computers, need to stay within a specific operating temperature range. Even though we run our facilities hotter than a typical data center, we need cooling systems - both to prevent server breakdowns and to provide a reasonable working environment for technicians working on the data center floor.
After servers, the second largest consumer of power in a data center is the cooling system. We needed a cooling system which minimized our overall energy consumption. For this reason, we designed our own cooling systems from the ground up.
This photo shows several of our custom cooling systems arranged in a row with racks of servers pushed against them on both sides. We named these units “Hot Huts” because they are sealed from the rest of the data center floor. Sealing away the hot air increases cooling efficiency.
