The Original Google Storage
In 1996 Larry Page and Sergey Brin, then Ph.D. students at Stanford CSD, working on the Digital Library Project, needed a large amount of disk space to test their Pagerank algorithm on actual world-wide-web data. At that time, 4 GB disks were the largest available, so they assembled 10 of these drives into a low-cost cabinet.
In Nov 1999, Google Inc., by then operating one of the primary search engines on the web, provided replacement storage capacity to the Digital Library project so that we could move this original storage assembly into our history displays.
As of September 2000, Google, now located in Mountain View, operated 5000 PCs for searching and web crawling using the Linux operating system.
