xsigo is a company that s makes Virtual I/O switch. They call it I/O Director. Kind of like what Cisco is doing with FCoE, xsigo solution allows servers to use Fiber Channel and Ethernet on the same cable. You have two kind of cables to choose, 1Gbps/10Gbps Ethernet or InfiniBand. You will need to install xsigo drivers on your OS to enable these virtual I/O. xsigo solution creates a huge competition for Cisco’s UCS solution, and Cisco is watching them.
