It is very cheap to do 32 TByte raw storage with SATA (2 TByte RE3 from WD)
in 3 rack units using off-shelf Supermicro chassis with zfs (raidz2),
e.g. with FreeNAS 0.7 or OpenSolaris. Remote synchronization is easy
with rsync or unionfs.
As far as I can see things become considerably more expensive with
larger drive numbers and higher drive densities, unless one uses
a cluster FS approach.
