Technocrat,

I think the problem with demos is that it has to be a big setup to show differences in class 2/3 traffic compared with the competition. The demos you are alluding to really have a trivial amount of traffic and there would probably not be significant differences. The info on the Sequent site shows the potential differences between cascading and multistaging when you are looking at a 64 port fabric. This is actually the reason that Cal Nelson gave me at the shareholders' meeting and I think it makes sense. If there are any working IT people out there - can you tell us what the logistics would be to set up this large of a fabric - how readily could you just drop it in at a data center to run a test?

On the single switch level - I think the CERN test of the Silkworm is as good as it gets. They also explicitly say how much of a bottleneck is due to the adapters and how much is due to the switch (the switch bottleneck is negligible). This contrasts with people who have tried to test Ancor switches in the past - got poor throughputs, and didn't seem to realize that it was the adapters. This is why a CERN test would be good PR and good marketing. Potential customers could just click on the CERN site for independent third party verification of switch performance.

I also have a standing offer to FC engineers to anonymously send me their opinions. Although this is a biased sample (they are reading this thread after all) - so far I have one (out of one) with an opinion that the MKII is a "technically superior switch". I have not heard anything from FC engineers the contrary, but would be happy to post those opinions as well.
