Yeah, plus I'd say that one memcached server for every five database servers would be a more realistic estimate. Joking aside, Dustin is right-- it's impossible to say how many memcached servers you need without knowing the size of the objects and exactly how many you want to cache. Realistically, too, the size of the memcached pool is of more importance than the number of servers in it, unless you're doing a particularly large number of operations... -- awl
