So I have a B85M-G43 motherboard with i5 processor with 32gb of ram. I have 4 1 tb hard drives in the box, one with server 2012, one with windows 7, one with my family pictures and 1 configure for my ESXi 5.5 that I have installed on my USB stick. I have another box that I am switching over as my primary box, so want to utilize the storage of the windows 7 and server 2012 hard drive. I use the esxi just for testing, and labbing. Would it be easiest to setup a NAS vm in vSphere, and then map it to my primary box to backup and store files, or what would be the best route for me to take? Open to suggestions.
