Apart from the recommendations you've seen suggested, perhaps your desire for the 10Gb firewall could be better addressed with a re-thinking of your design/architecture? You mention iSCSI traffic - passing that type of latency-sensitive traffic through a firewall would be a serious negative in my opinion. I'd bet $2 (or a single quid to you :) ) any iSCSI vendor would have fits troubleshooting an issue if you told them it was passing through a firewall. I guess that's where I'm pointing you is to reevaluate what/where you need to define access rules and determine whether you'd be better suited to using something other than a L3/4 device to segment/isolate traffic or access. If you're looking at running a consolidated SAN between a number of "limited" systems you've merely shifted your risk from IP/network to disk/SAN. Who's to say you couldn't get someone trying to elevate their level of access via the fiber-channel medium versus breaking through the Ethernet layer? Anyway - I think instead of trying to find the biggest hammer to strike all your little nails at one time, you might want to consider putting them into different boards in your house.

I'd like to be able to inspect at 10Gb wirespeed. As this is a scoping project (though it _has_ to happen due to the nature of projects in the institute), cost is not the main issue. I've come across the Nortel Switched Firewall 6000, however this 'only' does 6Gb throughput. Alternatively, we have several firewalls which work at 1Gb and are wondering if its a better to chanelize [sic] and put say 10 firewalls each dealing with different traffic. In coming years, IP based VPN's to other sites will become more used - and more 10Gb links to site perhaps building up to a 40Gb WAN backbone. We currently have an IDS which will can handle this much volume. The next question, is extending the SAN. If using iSCSI, is it better to leave this traffic off the firewall and just route it through, say a GRE tunnel without encryption? Would be keen to hear any thoughts on the theory of what I want to do. Implementation is not so difficult, really after some 'best practices' thoughts.
