Depends on how much, but yeah I'm interested. With my setup here I always need 
additional ports. PCI-X I take it? Lemme know how much you want for it

I've had problems with non-OE Broadcom NICs as well.  I just don't trust them 
anymore.  In fact, I've got a stack of Intel PCI-e dual-port Server NICs 
sitting here waiting to be installed in my servers to replace the last few 
integrated Broadcom parts I didn't get in my last maintenance cycle.

Kyle @ Hard|OCP just had a similar issue with Broadcom NICs.  They were moving 
the site and forums over to VMWare's ESX and as soon as they turned everything 
on the NICs buckled under the pressure of thousands of simultaneous connections 
and the servers took a dive.  From what he said, VMWare knows about the issue 
and is going to have a fix later this year (though I don't know if Broadcom is 
working on a new driver that will make its way into the Linux kernel or if 
VMWare is fixing the existing one for their use only).

(BTW...  If anyone is interested in a quad-port Intel Server NIC, let me know.  
I've got one and will, with 98% certainty, never use it).

My OF boxes are deployed in a different context and not with Exchange, so not 
really relevant to /this/ discussion; however what I was describing were errors 
on a network in which a Dell 2003/exchange server and various Dell Windows 
workstations were deployed, using a variety of different Broadcom chipsets 
directly on the motherboard, and /some/ of these workstations were producing RX 
packet errors at the switch. Turning off the offload engine solved most of the 
switch packet loss issues from the affected workstations.

I can't reproduce your errors since I don't have a similar setup with OF and 
because I also don't have spare hardware capacity or time right now.

All I was attempting to do was to suggest something you might care to look at 
what is a known cause of network problems, namely the Broadcom Offload Engine 
implementation, and eliminate that as a possible cause. 
If the issue persists with offload disabled then it would seem to point at 
other issues, possibly having to do with the switch, but also possibly to be 
resolved as others have said, by replacing with an appropriate Intel NIC.

It's my general experience that Intel NICs generally work flawlessly with 
almost every switch, and with almost every operating system.

Not sure I can help you any further.

Robert
