I use MD300i with FreeBSD 7.0 and 7.1 with iscsi-2.2.2. It work fine. 
But be careful to configure MD3000i. MD3000i assign by default first 
disk to preferred controller 0, second disk to preferred controller 1, 
third disk to preferred controller 0, and so on. First, third, fifth... 
disks is usable from FreeBSD, but second, fourth,... disks result unusable.
Work around: manually assign all disks to controller 0.
I'm talking with Dell's technical support, but Dell not support FreeBSD! 
In any case, technical support tell me, the problem (maybe) is the 
multipath. FreeBSD use only one path (only one IP) to communicate to 
MD3000i. Second net interface in unused.

I hope that I have been helpful.
