Securing your SAN over FC

I want to create a secure SAN with data encrypted in flight over FC. I think the host and disk side will need some hardware for encryption. Do you know of any such products? Is my thinking correct?

Your thinking is correct in the sense that customers have started thinking of protecting information over the FC network. Such information comes in two types: the management traffic and the customer data traffic. The management traffic often has less data to be encrypted and is considered more critical.

There are several vendors that are coming out with products that encrypt traffic at the two ends of the FC network, i.e. encrypt at the entry point and decrypt at the exit point of the FC network.
