Re: quiet dual dual-core opteron
It looks and acts like spray paint. Its a bit thicker and has a rubbery feel once applied. You can spray it over screw holes and then just poke screws through it if it occludes the hole. I don't know what you mean by "how much space does it take up", its just like applying a coat of paint. - Naz. Peter A. H.

How much space does it take up? Like, do I have to be careful about spraying it so that I can reassemble the case or is it unobtrusive enough to just spray everywhere?

Peter A. H. Peterson wrote: Hi All, I know this is a little something of a tall order, but I am looking to replace my aging SMP system with a dual, dual-core Opteron system (probably Opteron 265s). Noise level is a primary concern because our apartment is very small. I recognize that this is quite a constraint, but then that's what makes it interesting. The box will primarily be a server but may also run MythTV. (Just to make it *really* interesting.) I was thinking about using a ZMAX DP system, which is supposed to be Dual-core ready (or so I've read), but then I have heard that the ZMAX units run more around 50 db (more than the 38db on the ZMAX specs). Plus, there's not much room for upgrading and I would be forced to use USB network dongles... etc. And, I would prefer to use stock kernel or experimental drivers -- I don't want to have to use binary nVidia drivers. Is nForce3 fully supported without the binary drivers? Then I started thinking about using a K8T Master2 Far-7 board because it is only standard ATX and seeing if I could get that board into a Sonata II case... but I'm not sure if that is even possible and, once again, I can't seem to find a lot of specs about it or people who have tried. Does anyone have experience with a working dual, dual-core opteron system that is less than full-tower size and relatively quiet? Or even a quiet-but-full-tower machine? If anyone has experience with the ZMAX unit and can speak to its noise level (especially with dual core chips) that would be great too. I figured that even if you guys didn't know these pieces of hardware specifically, the peanut gallery would at least have opinions about the best way to make a quiet dual dual-opteron server.

Re: amd64 dualcore nad raid1
Apologies, I use a slightly different board, the one on the Tyan Transport Server Chassis GT24. Its the same chipset though, so you can pretty safely assume Sarge will have the same support for it. - Naz. Naz Gassiep wrote: I use that exact board with the same setup. The RAID1 on it is not true RAID, so I use the Linux Software RAID to set up two RAID1 arrays of 2 drives each (i need two separate physical arrays for my purposes). It works well, and performance is good. Debian Sarge with the 2.6 kernel detects all hardware nicely. I recommend that setup. - Naz Francesco Pietra wrote: i intend to setup a workstation for quantum mechanical calculations (organic chemistry) with a couple of amd64 dualcore 265 and a couple of STA hard disks 360GB raid 1 (mirroring for security reasons).

I plan to have 2GB ram, but that is not enough for the calculations and frequent access to disk occurs. Remember that i am based in italy where the market is under rigid control by whom you can easily imagine so that it is not easy to get what one wants (for example main boards). i am happy when i meet a handler who follows my linux requests, most do not. thanks for answering Francesco Pietra -- MrNaz photo gallery and journal at: www.mrnaz.com -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
