Is there any configuration parameters involved here?

We have an E4500 that sends data to an ATL P1000 (4/30 DLT7000)
via Differential SCSI 12 meter fast wide cable 
and the thruput we're getting is 2.61 - 3.71 MB/Sec.

The DLT7000 drive thruput according to vendor specs is
18 GB/hour (thats 5 mb/sec).

?
