Ok, well I've never seen a router with 1 port. I
thought we were talking about building a router?
The lack of PCIe cards is a good reason to consider a
PCIX machine. On the systems that we have, the 1x PCIe
ports are a lot slower than a PCI-X card in the slot.
You need 4Gb/s of throughput to handle a gigablt
router. (1 GB/s full duplex times 2). 1x is 4Gb/s
maximum. In my view, you always need twice the
bandwidth on the bus to avoid contention issues.
