My iMac specs:

-16GB RAM
-graphics: ATI Radeon HD 5670 512 MB
Trying to mount 24TB G-RAID with Thunderbolt 3. I assume its default formatted as RAID 0. Using USB-C (Thunderbolt 3) to USB 3 cable.
not recognized in Drive utility
not recognized in system profiler
I’ve tried the following:
different USB ports on iMac body (NOT keyboard)
reboot
reset SMC
plug into MacBook Pro (15-inch, Late 2016) running OS 10.12.6. Used enclosed thunderbolt 3 to thunderbolt 3 cable. Did not mount, nor was recognized in Drive utility or system profiler.
Problem solved:
I was plugging USB-C cable into Thunderbolt port on G-Raid. I was under impression that USB-C and Thunderbolt were interchangeable; am n00b.
But, G-Raid should have mounted on my 2016 MacBook Pro using Thunderbolt to Thunderbolt cable? Or are Thunderbolt ports on G-Raid only for daisy-chaining other drives and NOT for connecting to computers? VERY confusing.
They are only interchangeable on the Mac side. On the device side they are separate interfaces that are not compatible with each-other. This is standard as only Apple can combine them into a single port.
