James Hamilton, Windows Live Platform Services: Here's a statistic I love, Facebook is running 1,800 MySQL Servers with only 2 DBAs. Impressive. I love seeing services show how far you can go towards admin-free operation. 2:1,800 is respectable and for database servers it downright impressive. This data from a short but interesting report at: http://www.paragon-cs.com/wordpress/?p=144.
The Facebook fleet has grown fairly dramatically of late. For example, Facebook is the largest Memcached installation and the most recent reports I had come across have 200 Memcached servers at facebook . At the Scaling MySQL panel, they report 805 Memcached servers.
