funny you should mention google - because all their computers that run the
google sites, are.... no-name 1U and 2U x86 rack-mountable PCs, combined into
a set of large clusters.
they use a replicating file-system + lots of communicatoins redundancy +
monitoring software + lots of technicians and spare parts, to get the
reliability they want.

Yes but they are not 'mission critical'. I think that an example of what
SQL can do is Ebay (which runs on Sun and use some sort of Java server
technology).
I think that the best example of OSS heavy load servers were
ftp.cdrom.com (== Walnut Creek) who ran massive bandwidth and load on a
few servers on FreeBSD (and Slackware Linux). In 1998 too! Nowadays Pr0n
servers are among the highest loaded and fastest systems (and I often
test network speed and so on using that as targets <g> - imagine what
internet censorship would do to that - hehe). It is interesting to
notice that certain pr0n urls load 8 times faster than the google front
page under certain circumstances ... probably internet caching effects
..
