Intel EXPI9404PTL PRO/1000 PT Quad Port LP PCIe Network Adapter

SKU CH-HT8Y-Z28SV

Quad-port Gigabit Ethernet PCIe card with Intel I/OAT for multi-processor load balancing and both full-height and low-profile brackets included

  • Four Gigabit ports multiply server bandwidth
  • PCI Express x4 interface fits standard server slots
  • Low-profile and full-height brackets both included
  • Intel I/OAT offloads CPU for faster I/O
  • Balances traffic across multiple Xeon processors

Quad-port Gigabit server adapter

The Intel EXPI9404PTL PRO/1000 PT provides four copper Gigabit Ethernet ports on a single PCI Express x4 card. It is designed for multi-processor servers that need to distribute network traffic across several CPUs. Both full-height and low-profile brackets are included in the box.

PCIe Gen 1.0 or 1.1 x4 interface

The adapter operates on PCI Express generation 1.0 or 1.1 using a physical x4 link that also fits x8 slots. This bus width determines whether the card can deliver full throughput on all four ports simultaneously. Systems limited to narrower lanes or newer PCIe generations without backward compatibility will not support this adapter.

Four 1000 Mbps ports with Intel I/OAT

Each port runs at 1000 Mbps and the controller supports Intel I/O Acceleration Technology to offload TCP/IP processing from Xeon CPUs. The card handles typical server workloads such as virtualisation networking, storage access and web serving. It reaches its limit when aggregate traffic exceeds the PCIe 1.1 x4 bandwidth ceiling or when 10 GbE speeds are required.

Highlights

  • Four Gigabit ports multiply server bandwidth
  • PCI Express x4 interface fits standard server slots
  • Low-profile and full-height brackets both included
  • Intel I/OAT offloads CPU for faster I/O
  • Balances traffic across multiple Xeon processors

Questions about this item

What real-world throughput does the 1000 Mbps per port deliver in a server?

Each port runs at full gigabit line rate so the quad-port design can move up to four gigabits of traffic simultaneously when the host CPU and PCIe bus keep pace.

How does the PCIe x4 Gen 1.0/1.1 interface limit total bandwidth?

The x4 link caps aggregate throughput at roughly 10 Gb/s (1.0) or 20 Gb/s (1.1), so all four gigabit ports can run at line speed without hitting the bus ceiling.

Which bracket should I use for a low-profile chassis?

The box includes both a full-height bracket and a low-profile bracket; swap to the low-profile bracket to fit 1U or slim enclosures.
