What is sad is that these controllers are becoming very mainstream now,
we're getting them more and more on Dell servers , and the fbsd project
still struggles with them (for reasons I don't know, might be LSI's
fault, might be a lack of resources or interest...)

I'm having a very hard time defending the use of fbsd for firewalls at
work, with the recent release of debian kfreebsd.

What's saving fbsd for the moment is the lack of a proper CARP
implementation on debian kfree.

Actually, cc'ing the list, I'd like to share my feelings on this.

I'm trying very hard to keep freebsd at work for our firewalls.
Recently, I installed new blade servers shipping with h700 controllers
(these attached to mfi w/o problems).

If, for some reason, we get h200 cards using the mps driver, I'll have
to install using software RAID instead.

This would be a *disaster* and extremely hard for me to justify to my boss.

The staff in the datacenters check the machines every day, making a
routing inspection to ensure no server has orange warning lights.

Typically when a hardware RAID's hard drive fails, the lights go orange
thus prompting them to warn us (in case we missed the nagios alert) for
a replacement.

If I had to use software RAID, we'd be giving up on this extra security
and, again, I'd have a very hard time justifying it.
