It actually does have a controller, it is the disk controller card in the E220, (two if the D1000 is split to go to each E220). As you say, it is ' SCSI box sitting on a scsi bus', or JBOD, (just a bunch of disks). They are not really talking to the disks directly, but there is no additional hardware controller on the D1000, only a common bus.

With Veritas Volume manager, you can spread the I/O across multiple drives by creating logical RAID volumes and do load balancing.
