through a horrible build that finally hinged on an incompatibility
between a 3Ware card and a new SuperMicro X10-DRI motherboard. Boots
would just hang. Once I installed a newer LSI MegaRaid card, all my
problems went away.
Of two vendors 3ware and Supermicro (if it is hardware defining choice)
3ware wind hands down for me. I gave up on Supermicro some time ago. I
prefer Tyan system boards instead. Several supermicro boards died on me:
all of them were AMD boards, dual or single socket workstation class
boards. They died of age, somewhere in their 4th year of age, starting
memory errors (and these are not due to mem controller which is on CPU
substrate - I attest to that), and few Months later they would die
altogether. I ascribed it to poor system board electronics design, and
poor design of even one class of their products is a decision maker - at
least for me. So, as far as system boards are concerned, I'm happy with
Tyan, whose boards I'm using forever, who is in server board business
forever (which was true even when Supermicro just emerged).
As far as RAID cards are concerned... This is a bit more difficult thing.
I do use both LSI and 3ware. 3ware outnumbers LSI in my server room by a
factor of 5 at least. LSI is good solid hardware that exists forever
(pretty much as 3ware does). For me big advantage of 3ware is transparent
interface. By which I mean web interface. There is command line interface
for both and 3ware command line interface may be less confusing for me.
But transparent web interface available in 3ware case it real winner in my
opinion. As, when dealing with (very good, which both are) RAID hardware
the screw ups happen mostly due to operator error (OK, who of you guys do
not screw up even with confusing interface are geniuses in my book - which
I definitely am not).
Sorry for long comment. I did feel 3ware deserves more respect than one
might draw from this thread otherwise.

suggest everyone stay away from 3Ware from now on.
