Have you ever asked your self where does Google buy its servers, Dell, HP, IBM, or Sun?
Unlike everyone in the world, Google don’t buy servers from different vendor they build them!
It doesn’t make sense if you have 100 or 1000 servers, but if what about if you have hundreds of thousands of servers, which is the case for Google.
Actually Google have long time ago stated that they their own server, but the company revealed many new details about its servers, and operation.
- Each server has its own battery. (reason check next item)
- No UPS in the data center. (reason check previous item)
- The unit of the data center is a container, not a server, and not a rack, but a whole container. (Sun sell something like too).
- x86 because it is cheap.
