10Gb Firewalls

[Kerry Milestone <km4 () sanger ac uk>]

Hello kind Wizards,

I am investigating the possibilities of putting a firewall on the end of 
a 10Gb link.  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.


Many thanks,
Kerry.
