Hi Jim,
Thanks for your answer, I was thinking some of the same, but I was not sure...
:-)

Just for the fun, we will create some ISA servers with 10GB interfaces, and see
how "high" we can go... (Non production)
Thanks
Jesper Hanno

There is no such thing as "application-level filtering at 10GbpS wire-speed";
especially not on a general-purpose server OS.
Additionally, ISA itself neither knows nor cares about the NIC speed; you could
have them operating at 1TbpS and ISA itself wouldn't care.
At those speeds, the entire system (system bus, memory, CPU) will be your
bottleneck.
The PCI bus tops out at 133MHz; even for PCI-e. 1Gbps nearly fills this pipe
at ~100Mbps. Even with the NIC using DMA, your memory bandwidth is shared by a
system busily handling other memory allocations and management. Since this is
all I/O processing, the CPU caches are very nearly irrelevant.
IOW, tell your customer to wait about 10 years before they seek a
general-purpose server system to handle "10-100GbpS wire-speed
application-filtering and a bag o chips".
Jim

Hi Tom,
I saw that test, but it´s pretty old, and as I remembered it, it was the test
setup that was the limitation....
does anyone tried ISA Server with 10GB Adapters....?
Thanks

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.

He Everyone,
Does anyone have an idea for creating a ISA Server 2006 EE using 10Gb
Adapters...
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
