You're mixing up bits and bytes. Your fibre hba is 1 Gb (little b = bit). Your drives are capable of 120MB (big B = byte). So you're trying to put 120MB of data down a roughly 100MB pipe.
I'd say that for each LTO-4, you're going to need a dedicated 1Gb HBA or upgrade the HBAs switch to 4Gbps and then you can get away with only 2 of them.

If I was running only six LTO4 drives that is capable of 120MB on a 1GB fiber hba, would that be a bottleneck? 120 x 6 = 720MB even though the switch is 1GB?
