Unless you have multiple gig nic's or multiple fiber channel cards
you're looking at about 70 to 90MB/sec max, depending on gig v. fc.  6
LTO drives would very much like more incoming data than that...

Figure an average of 15MB/sec each to be conservative, you're looking at
completely maxing out a single fc connection and over saturating a
single gig connection.  And if any of them wanted to do 20MB/sec, well
you're just sol.
