Sadly they're moderating comments. I tweeted at the author, with links to WMF Ganglia as backup, and he definitely doesn't believe me; maybe something from a WMFer would help, if anyone thinks it's worth correcting: https://twitter.com/hassankhosseini/status/370090365354655744
Going by the Ganglia pages, actual Wikipedia has at lesat >2x the *RAM* that their scenario has *disk*. Pretty fun. (If you're curious, Ganglia's front page says it's tracking 14,744 cores on 988 hosts and 40T of RAM. Their scenario has <20T disk. There may be additional capacity not in that Ganglia setup, though it seemed to cover the obvious stuff.)
