HP Blade BL20p Server + SAN

I am trying to figure out everything I need to set up a Blade BL20p system and SAN. I need to know what components I need to buy to hook up my Blade to the Brocade Switches. Does the Blade enclosure come with connectivity to the switches when they are plugged in or do I need some kind of fiber card for the blades. I am looking at 6 Blades and want redundant connection to the SAN so I will have 2 Brocade switches. Can anyone tell what I need for this.
