Be aware that the NPE-G1 can't handle more than approx. 550kpps on its own GigE interfaces. I've heard this before but now Marcel (@BIT) has confirmed it with measurements done with an Agilent test system. I think any NPE-* including the G1 can't handle even remotely that many kpps with an PA-GE in any of its slots. The 7206VXR backplane is a simple (dual left-right) PCI32-33MHz bus as found in any commodity PC. On the NPE-G1 the GigE interfaces are directly coupled to the CPU crossbar and do not touch the PCI bus. That is why you get two unloaded buses (left and right) on the slots with the NPE-G1. Considering the price tag of an NPE-G1 with a 7206VXR chassis around it, it fares really poorly against any server-class P-IV/Opteron board with PCI-X GigE cards. With FreeBSD you get 500kpps easily and with some little tuning you can drive it up to over 700kpps. -- Andre _______________________________________________ swinog mailing list [EMAIL PROTECTED] http://lists.init7.net/cgi-bin/mailman/listinfo/swinog
