Largest production memcached install?

No clue if we’re the largest installation, but Facebook has roughly 200 dedicated memcached servers in its production environment, plus a small number of others for development and so on. A few of those 200 are hot spares. They are all 16GB 4-core AMD64 boxes, just because that’s where the price/performance sweet spot is for us right now (though it looks like 32GB boxes are getting more economical lately, so I suspect we¹ll roll out some of those this year.)
