i have 8 smp machines (dual p3 450mhz, 512M ram) using intel mb with onboard
ncr876 scsi, and two 9gig quantums in each. running software raid1 on all of
the disk, except small swap and /boot partition on each disk. using kernel
2.2.12 with the 2.2.11 alpha raid patch.
also have a couple of older dual ppro boxes, also using scsi and slightly
older kernels (~2.2.6) similar config.
i have never had _any_ problems with any of them, other than hardware troubles
(couple of dead disks, one of the ppro mainboards got fried) they are rock
solid, terrifically stable, and fast as all hell. i have been using software
raid on smp machines since 2.0.34, and have never once had a software problem
that was not caused by faulty (read: cheap) hardware.
the key for us has been using a solid kernel compilation, with few patches,
and no hokey, half supported hardware like add-on ide controllers.
not to harp, but i hear a lot of noise on this list from folks who dont like
the cost of scsi, and declare it is not worth the difference. i am not made of
money either, and when they work 100%, ide systems are a great cost savings.
but why is it that people (read: gamers) will ante up for twin cpu's, but wont
buy a scsi card and a couple of decent disks? i hate to be a wet towel, but
sometimes, guys, the old addage still applies-
you get what you pay for.
