Head on over to vinf.net for a really informative posting on how HP Virtual Connect (VC) modules work. These modules can initially cause some real confusion and can take a while to get your head around how they work.
Virtual Connect modules are an option for the HP C7000 Blade Chassis, they offer great flexibility and can reduce the time taken should you ever need to swap out one of your HP Proliant Blades due to hardware failure.
The article starts by giving some basic background information on VC’s and then proceeds to give clear and easy to follow details on areas such as configuration, port mappings and fail-over.
Definitely worth a read!
