IMHO opinion I do not think FreeBSD is there...yet.  ZFS is addressing
many of the enterprise filesystem features that would be needed to
implement something on this scale, and there is the iSCSI target from
NetBSD available in the ports tree.

I think 7-RELEASE is going to be a solid foundation for building
solutions like this - but in the mean time it may be worth considering
OpenSolaris if are considering going the COTS path.

or - you can take a look at a company like Isilon Systems
( which builds very scalable filers based on
FreeBSD.  I have beta tested their iSCSI implementation and it does
look good.
