I have been looking for the G-RAID with Thunderbolt RAID Configurator everywhere… Where is it? can’t locate it on the downloads page anywhere… Please help 
Oh I have found the raid configurator in Mac OSX now (in High Sierra) but it won’t let me configure the 8TB G-raid with thunder bolt unless I select the SSD that is in the Mac Pro tower as well. the SSD drive is the main drive for the computer… is this correct?
After you have configured the drive you will have to go into Disk Utility to erase the drive. On High Sierra for some reason Apple decided to hide unformatted drives by default. Click the view box on the top left and select Show all devices. You will then see your drive and can erase it.
Thank you very much, the show all devices button is a great tip. This is not explained well in the Mac instructions from apple. And I used your configurator which actually does JBOD not the concatenated JBOD that apple offer… So thank you this has made me very happy
