Quad-port Gigabit adapter

The Intel EXPI9404PTG2L20 is a PCI-Express network card that provides four independent RJ45 ports, each operating at 10, 100 or 1000Mbps. Dedicated PCIe bandwidth gives each port full Gigabit throughput without sharing the bus. The adapter balances traffic across multiple processor cores in multi-CPU servers. It fits standard low-profile or full-height slots with the included brackets.

Server and virtualisation hosts

This card suits administrators who need four copper Gigabit links for virtual-machine networking, storage traffic separation or link aggregation on Category-5 cabling. It is not for buyers who require higher-speed uplinks or fibre connectivity. Desktop users with a single network cable will not use the extra ports.

PCI-Express interface

The adapter connects through a PCI-Express slot, delivering dedicated bandwidth to each of the four ports. This interface choice determines whether the card fits the target server or workstation. Verify that the system has an available PCI-Express slot before purchase.

Questions about this item

Which speed rating should I pick for a mixed 10/100/1000Mbps network?

The adapter runs at 10, 100 or 1000Mbps on each port, so it matches whatever switch speed you connect it to without manual selection.

What does the 1000Mbps rating deliver inside a server?

Each of the four ports gets dedicated PCI-Express bandwidth, so full gigabit throughput is available simultaneously without bus contention.

What does the PCI-Express interface cap in practice?

The PCI-Express link provides the per-port bandwidth ceiling, keeping each RJ45 connection at its negotiated 10, 100 or 1000Mbps rate.
