I already have a msa1000 with 28 hard drive install using 2 dual bus adapter per 14 drives. What I want to do is add another msa30 to my system that will max me out for the msa1000 with 42 drives. Can the new msa30 that I purchase be a dual bus or do I have to have a single bus. If I can have a dual bus on all three (14 drive) encloser how do I connect them together?
