As you know from my prior blog, blog, the Dell FC Flex IOM adds 4 x FC ports (8 x FC ports with 2 modules) to the Dell MXL/IOA blade switch and transforms it into a NPIV Proxy Gateway (NPG) allowing for the bridging of FCoE and Fibre Channel at the switch blade level. Check-out the video here on YouTube (also embedded below) or on the Dell MXL wiki page (second video on page) that steps through the details and ease of deployment of this solution.
