I recently visited the University of New Hampshire InterOperability Laboratory (UNH-IOL) for a behind-the-scenes tour. This 32,000-square-foot facility is the place where networking vendors large and small go in order to certify that their technologies interoperate with each other. The lab has more than 20 different testing programs which produce independent results via collaboration with networking and storage vendors. You name it, they test it: Etherent, IPv6, data center bridging, Fibre Channel, SATA, Wi-FI.
