Hi Jesper, "wire speed" might be a problem. From numbers I've seen, the ISA Firewall tops out at about 1.5 Gbps. Of course, that could be a limitation of the testing enviroment, but I don't know what their besting environment was like, so I can't say.

My customer have the following requirements: - ISA Server 2006 EE (Array) - 3 x 10 Gb Interfaces Internal1, Internal2 and External (Would be upgraded to 40 and 100 Gb doing 2008!) - Must deliver "Wire Speed" - Route between Internal1 and Internal 2 <> External My Questions to this configuration: - What kind of Server could handle this setup? HP 580 ? - How many ISA Servers should we place in the Array (2, 4 or more?) - Number of CPU´s and kinds ? - where will the bottlenecks be ? (The PCI bus ???) Thanks Jesper Hanno
