I would like to thank everyone for the suggestions here. What I ended up doing was the following:
Installed Windows Server 2016 Standard bare metal
Installed the drivers for the HP RR
Installed DP and Scanner
Installed the Hyper-V and Essentials roles to get support for VM's and Client Backups again
All seems to be working as expected now. Emby is running on an Ubuntu 16.04 VM and NextPVR on a Windows 8.1 VM. All paths for media, transcoding, timeshifting, and recording pointed to the DrivePool, and it is working great!
