NAS w/ multipath

[Palle Girgensohn]

Hi!

I'd like to connect a FreeBSD system to an IBM NAS system, using a 
FibreChannel connection. I can find two supported drivers in the system, 
mpt(4) and isp(4). It seems to me, none of them supports multipath, 
something we need. Is this a false assumption? Are there other drivers that 
do support multipath? Recommendations apprecieated.

If not, an alternative would be iSCSI, but I have no experience and it 
seems it is hardly implemented at all for FreeBSD, is that true?

Thanks
Palle
