We have a BusTech MDL. The doc also refers to it as MAS. It has performed very well for us. We pur chased before EMC did, and ours is backed by NetApp disk on a storage rack that is shared with a distributed system.

I really don't know the history behind the Bus-tech and I think I used "MDL" when I shouldn't have to refer to it pre- HDS (or is that not even correct). Was the original just called "MAS" (Mainframe Appliance for Storage).
