I've actually received a 'gift' from 'happy customer' and i do have
extra 9500S-8 to be able to maintain testing future updates for the
support, so yes, i am committed to that.

There is 'limit for command/LUN' and 'clustering patch' with the kernel
included on my U3-images, but later on i've learnt that those aren't
really needed. RedHat had somehow/for some reason made
'ENABLE_CLUSTERING' 0, so maybe the clustering patch should be there.

Initially i thought it to be good for limiting the driver allocations
etc. for queue with tampering the .h, but that is not actually making
any good. The TCQ lenght (254) is too deep anyway, so using something
like

options 3w-9xxx cmds_per_lun=64

in /etc/modules.conf would be in place. Actually my findings being that
best for performance vs. responsivenes would be that included in patch

options 3w-9xxx cmds_per_lun=8

The ext3 problems i am seeing are not the drivers fault and i am pretty
sure that it's those nasty lock_kernel() and it's other locking friends
that are actually causing the random performance drop. It's still under
investigation/debugging.

I am anyway decided to go with my XFS patch for my NFS-server as the
ext3 just can't compete with XFS.

XFS being out of the David spcification as it's tapmering with the
general code paths - even tho it's nothing major.

There would be another patch too for those people using new shiny
SATA+everything motherboards. sk98lin driver beig unsupported by
redhat, it doesn't support Marvel/3c940 GBe either. I have patch to
make that as 'sk98lin_707' and placed to drivers/addon. I just realized
that enabling the NAPI caused my problems here, so i need at least
update the kernel after we get the U3 out.

Then there would be the forcedeth support (NForce3 integrated
ethernet). which isn't tampering the general code patch either. Given
that i only have NFforce3 150, i have only been able to test the
10/100Mbit/s version, but that patch should contain support for GBe. It
has vorked flawesly for me.

Yeap. I've tested that much more under ia32 than x86-64. Actually the
card i'll use near future for my new home NFS-server, will be ia32. I
have suitable box for it (== don't want to tie by x86-64 resources).
dual-PIII with 3x66Mhz/64bit PCI will just hold the 3ware and GBe
(which is pretty much what my NFS-box needs). There isn't much extra
gain for using faster box as this is writing that 100MB/s with XFS. The
very same i get for dual-opteron with all the fancy new dual-channel
DDR and multiple PCI-X. The PIII cannot go for over 200MB/s for reads,
but i am willing to loose 'that much' :P


But you need the anaconda mods and hwdata too, if you're making thise
'just happens to load automagically thile installing' .....
