How Google Works
.----
| Specifications:
|
| * Over 450,000 servers[1] ranging from a 533 MHz Intel Celeron to a
| dual 1.4 GHz Intel Pentium III (as of 2005)
| * One or more 80GB hard disks per server (2003)
| * 2–4 GiB of memory per machine (2004)
|
| The exact size and whereabouts of the data centers Google uses are
| unknown, and official figures remain intentionally vague. In a 2000
| estimate, Google's server farm consisted of 6000 processors, 12,000
| common IDE disks (2 per machine, and one processor per machine), at
| four sites: two in Silicon Valley, California and two in
| Virginia.[6] Each site had an OC-48 (2488 Mbit/s) internet
| connection and an OC-12 (622 Mbit/s) connection to other Google
| sites. The connections are eventually routed down to 4 x 1 Gbit/s
| lines connecting up to 64 racks, each rack holding 80 machines and
| two ethernet switches.
