It's only in our lab and only for testing, so ignore the fact that it's RAID-0.
Physically we have 2x750 GB hard drives. you are correct that OpenE is installed on 2 GB of the first drive. So you're saying that I can't use the remainder of the drive + the 2nd drive to create a RAID-0? It's not a biggie as this is just for testing but it seems really odd.
