Some people claim that some of the ATX2.0's work with the EPS12V pin-out. I doubt that, but I do know there _are_ "universal" ATX, ATX12V, ATX2.0, EPS12V power supplies from Enermax and others. I was curious if Antec's was as well. Other than the 24-pin connector, the 8-pin (4x2) SSI Server connector is the biggie. That's what gives you not only extra +12V rails, but more importantly, +3.3V rails -- something the P4 doesn't. > Its pretty clear that it's an EATX case. My bad. Do you have an SSI EEB > case you like? In the rackmount space there are plenty. The 3U route seems to be best, because: 1) They typically have the best price for the expansion point 2) You can typically use standard ATX/EPS12V power supplies for non- redundant (as well as pay more for a 1+1 or 2+1 setup) 3) You can typically fit full height expansion cards 4) You typically get 1-3 sets of 3U x 3U (5.25") bays If you have even more drives (16+), I'd go for a full pedestal setup. Just get one that you can always rackmount later (as 6-8U). > I'll go back and look, but I didn't see any entry specifically for > PowerNow. Plus as I said, installing kernel 2.6.12.3 fixed the errors. And that's great news. I've been installing the older Opterons in the past. I actually haven't setup an Opteron server in over 3 months now (I believe?), only Athlon 64s in desktops. > Will do. I'll run the benchmarks tonight. Well, don't do it for my benefit. I don't want to create work for you. But if you're still testing, it's always a consideration. Especially with 4 disks, which is ideal for RAID-10 without losing much usable storage over RAID-5 (only 33%). Just remember to update your 3Ware 9w-xxxx driver and firmware, as well as 3DM2. -- Bryan J.
