No. I think you are confusing the A1000 and the D1000.
The A1000 has a hardware raid controller and a single SCSI
connection to a Ultra High Voltage Differential controller.
The D1000 has no hardware raid but can be split so that
two controllers can be used, one for each half.
These devices are getting old; you should look for something
more modern.

The A1000 supports multiple LUNs with different configurations,
but it's all hardware RAID. Why would you want the extra work
of having to do software RAID?
