Well, same here - but recently I was posed an interesting problem, that in the IP/Ethernet world, is a fairly trivial undertaking:Ĭan we merge our IBM SAN with our Cisco/Hitachi SAN, so that Servers on one can access Storage on the other, and vice-versa?Įver the idiot optimist, I immediately responded "Sure, that's like 10 minutes of work or something right?", and so dear reader, we begin. Storage Area Networking (SAN) is something I'd guess most Network Engineers have heard of, or some limited exposure, but not much maybe you've done some zoning for the Storage Guys on your Cisco N5K boxes, but otherwise it's a bit of a dark art. ![]()
