Many people get confused as to why so many I/O modules are needed within a given blade chassis. The basic concept is simple (in most cases) – for each port you need on a given blade server, you need to have a corresponding I/O module. For example, if you need 4 NICs, you’re going to need 4 Ethernet modules (in most cases.) In today’s post, I thought I would keep it simple and publish the I/O diagrams of Cisco, Dell, HP and IBM chassis. Of course, I am human and “have been known to make mistakes – from time to time” so please feel free to correct me on any errors you see. Enjoy.

They make it look so complicated in the movies. Detailed covert operations with the intent to hack into a casino’s mainframe preceeded by weeks of staged planned rehearsals, but I’m here to tell you it’s much easier than that.
This is my story of how I had 20 seconds of complete access to The Venetian Casino’s data center, and lived to tell about it.
