freebsd stable - Jan 2006 - SCSI RAID card recommendation (1/2 height PCI-X U320 SCSI dual channel)

Boy... what a major disappointment I just had...

I got in my SunFire X4100 dual opteron server and a LSI MegaRAID  
320-2X PCI-X card.  Unfortunately, the Sun seems to only accept 1/2  
height cards.  Totally lame.

Anyhow, I'm having a hard time finding 1/2 height U320 RAID cards  
with dual channels (I can't imagine how the connectors would fit, but  
hey I can hope).  Does anyone have any recommendations?  Naturally  
I'm going to run 6.0-RELEASE on it.

Ok... seems that my only likely candidate is the Adaptec 2230SLP.   
I'm not a big adaptec fan so I have little experience with these.   
There was a discussion on the -scsi list  a year ago and the card is  
listed as supported, but it is hard to find how stable these cards  
are and how well they perform under heavy I/O + network load.

The only other aac controller I have is a Dell PERC type which is god- 
awful slow, but I hear that's dell's fault not adaptec's.  I
don't
know what to believe there.  That card is quite stable however.

Any experiences with this that anyone wishes to share?
