One of my server has 2 PCI slots which has already plugged with 1GB Ethernet cards. I want to add two more 1GB NIC to this server. I've found on ebay this pci extender.
I want to ask, because I didn't use PCI Extender before. Does PCI extender cause performance lack on GB Ethernets? Will I able to get GB speed on these ethernets if I use PCI extender? Is one PCI slot able to run 3 ethernet cards at full performance?
Or is there any PCI extender on PCI-ex for performance? Or do I have to change motherboard to add more NICs?
