True :-) Still, my point was, I have run news servers out of the box on 2.0R, 2.0.5R, 2.1.0R, 2.1.5R... even on a GENERIC kernel (but you really need a custom kernel if you want it to work "well", GENERIC seemed to develop problems around 70 simultaneous readers). > > > And its only on a single T1 (so was howland.reston) > > > > Howland?

Guess you can play with words, but in my opinion, not if it's just a controller... a real RAID includes little things like hot swappability, redundant power, things that require hardware. ;-) I thought when I looked at the DPT stuff it was just a controller like the Adaptec 3985 "RAID" controller, but had some cache RAM on it too. That's great from the computer's point of view, of course... :-) but I am still hesitant to call something that is not a complete solution a "RAID". I will grant it "RAID controller" though. > Now you can go with an external Mylex RAID box but the DPT stuff works > just as well.

Freenix as of July doesn't even LIST you :-) (looking for: "intersurf", maybe I should be looking for something else) Considering that the box was deployed at the beginning of summer and I have not really even started pushing a lot of newsfeeds off of it, the fact that it splashed into the Top 250 it's first month online and the Top 100 it's second month online was pretty impressive I thought. Hmmmmmmmm no wonder, look at my daily transmission totals... TOTALS 1341 1205487 840575 164662 74995 69% 866:44:58 Almost 70% acceptance from remote sites is nice to see..
