You're a filthy tasteless queer if you don't rackmount your desktop as well, that's another 4U. Also, that big of a UPS will be 2U minimum, and it's best practice to have 2.
>what's the point of fiber
jesus christ anon how do you think you're going to get those files from your storage to your servers and desktop? Even if you went with 4-port 1gbps NICs and set up link aggregation on the switch, you're looking at 4gbps tops, and you're wasting any and all speed potential. If you're doing a proper SAN, you're critically bottlenecked, especially if you're doing virtualization on both servers.
However, 10gbps single-port switches go for $20 on ebay right now, Mellanox brand. Cheaper than fiber. It just doesn't look particularly exciting while plugged in. Have fun shelling out for the SFPs, though.
