I'm not sure whether you're looking for a network block device, or a 
distributed file system, but there are a few options: iscsi for freebsd 
(very new, patches floating), ggate (geom gate - share a geom device 
over the net), and nbd serving from FreeBSD.

As far as a distributed file system for FreeBSD, the only real options 
are NFS, coda, afs, and Ivan Voras' tdfs (runs under Fuse, probably 
lightly tested).  There is no cluster file system for FreeBSD (this 
makes me very sad), and I've tried at length to gather people to build 
or port one.

What are your needs?
