So yes, you'll run into the same issue there. Again, right now we have 64bit scsi emerging, so you might be lucky. The big advantage you have with fibre is that the scsi processing can usually be largely changed by a firmware upgrade - ICP vortex i.e. has recently released working versions of their firmware (http://www.icp-vortex.com/english/new/new_e.htm). 1.11.4 was supposed to do the trick but 1.11.6 actually does... Of course that still assumes your raid itsself can handle volumes larger than 2TB... Peter.
