I've got a Blade-system with 16GB RAM, but "only" one 140GB
harddisk. My question is about swap-space: Traditional knowledge
recommends swap = 2*RAM. This would mean 32GB swap (!).

Should I really go for 32GB swap space? Or will e.g. 16GB (= RAM-size)
be enough? 

Please note, that I don't do kernel debugging etc. on this machine -
just a production machine used for network monitoring (Mrtg, nfsen,

TIA for any clue,
