I never got the impression dmraid was that stable yet, but perhaps
someone could add that support in, if it actually works. Probably part
of the problem is that many of those that could do it, don't care to as
they don't run windows and would prefer linux software raid. That is
one of the problems we have with open source free software, only what
people care about is being worked on (where it is the what the
implementor cares about that matters, not the end user).

What can you currently buy that is better than the 3ware for running
with Linux?

Well they do appear to have open source drivers, and have a neat card.
Nice to see someone else getting into the business doing the right
thing.
Too bad their web site or rather ftp server is a mess. Many of the
links on their web page give ftp errors about module not currently
available (including the linux driver dir, many of the manuals, etc).
Now if I could see their manual I would be able to tell if their PCI-X
card works in regular PCI slots, and how many machines have PCIe x8
slots yet? I have seen x1 and x4 quite a bit, but not x8.

Raid6? Will have to look that one up.

To me those benchmarks say "Get the 3ware instead".

Yeah that's one of the ftp dirs that doesnt' work right now.

That would be a rather large number of T1s in one system.

Well no simple solution it seems, given I don't believe dmraid is
considered very robust or stable yet. Given lvm and software raid only
made it into the Debian installer fairly recently, I am not surprised
support for dmraid did not. Things have to be rather stable and well
understood to make it into the installer as far as I can tell.
I can't even figoure out if dmraid works isng the dm-mirror module, or
something else that isn't even included in the standard 2.6 kernel
sources.
