Thats for sure a S110. If you boot into LCC you can also enter a S110 menu and there are option to convert disks from raid to non raid. Not sure if that helps but as long as the server doesnt regonize the disks you cant more forward.  
Hello,  I don’t know much about servers, or computers in general for that matter, lol.  I recently bought a dell poweredge r720 to host a Minecraft server on, the server was only missing the hard drives though. After buying two Dell 1TB sas6 drives, I installed them and they both turned green.    After trying to install an OS, I noticed my server was only recognizing 32GB of space (it was recognizing the flash drive I had plugged in) and that’s it, both lights were off on the drive bays. I turned my r720 off, then turned it back on.  To my surprised, they both flashed green about 3 times before turning off again. I honestly don’t know why they’re doing this, but I’d really like to find out. I asked various forums how I could fix this, and every person who’s replied told me to configure raid. However, my poweredge wouldn’t let me, as no drives were being detected.  again, I’m new to all of this, I’d really like to fix it but I don’t know how.
