Preface: I'm new to Xpenology and DSM...
Long story short, I'm building a new (really just reallocating hardware) 24x SAS drive SAN and decided to run Xpenology on it following THIS to do the install and THIS to increase the disk capacity beyond 12 drives. Everything went great. I had a couple 3TB drives that I copied my vCenter VMs to, took all of the SAS drives from my hosts, put them in the 24 bays of my SAN, and started to migrate the VMs to the two R10 arrays I created via iSCSI
