Of course, but since I'm planning to buy this new server just now I'ld add more RAM on its list, instead of buying it after few weeks. >> (without PAE or similar things, it's a "normal" P4 machine) PE> You have to use kernel PAE option if your fbsd4.x box should be able to PE> use anything above 4gb of ram.

I'm afraid of PAE because of some "glitches" I read about with some HD controller drivers. Without PAE I feel more "safe" :) This will be a _very_ critical production server and I'm just taking all precautions I can in order to gain maximum availabily and stability.

Unfortunately for my purposes 5.x is not yet an option, also if I'm waiting 5.3-rel. for start an our own internal test program :) >> Anyone with similar experiences could, please, remember me actual >> limits ?

May I ask you, if possible, which HD controller drivers are you using ?

Yep, sorry but I was not sure which list was the correct one for my question ;) :( Many thanks !! -- Alessandro de Manzano System & Network Administrator Playstos - TIMA S.p.A.
