Overview

The Intel EXPI9402PTBLK PRO/1000 PT Dual Port Server Adapter delivers two independent Gigabit Ethernet connections through a single PCI Express x4 slot, making it an efficient choice for servers that need additional network interfaces without consuming multiple expansion slots. Each port operates with its own dedicated PCIe bandwidth, ensuring that heavy traffic on one interface does not degrade performance on the other. This dedicated bandwidth model is a significant improvement over older shared-bus architectures, where multiple ports competed for the same throughput ceiling.

Designed for multi-processor server environments, the adapter supports Receive-Side Scaling on Windows Server and Scalable I/O on Linux, both of which intelligently distribute incoming network traffic across available CPU cores. This prevents any single processor from becoming a bottleneck during high-throughput operations. The dual-port layout is naturally suited for link aggregation setups that combine both ports for increased bandwidth, or active-passive failover configurations that maintain network availability if one connection drops. Compatible with standard Category-5 cabling, the adapter integrates into existing network infrastructure without requiring upgraded wiring.

Pros & Cons

👍 Pros

  • Two independent Gigabit ports on a single card reduces the need for multiple adapters
  • PCIe x4 interface provides dedicated bandwidth without the bottlenecks of shared PCI buses
  • Receive-Side Scaling and Scalable I/O distribute network processing across multiple CPUs efficiently
  • Intel's proven server-grade networking silicon delivers reliable long-term performance
  • Low-profile plug-in card form factor fits standard server and workstation expansion slots

👎 Cons

  • PCIe 1.0A specification is outdated compared to current PCIe 3.0 and 4.0 server adapters
  • Limited to Gigabit Ethernet with no support for 10GbE or faster networking standards
  • No advanced features like hardware iSCSI offload or RDMA found on newer Intel server adapters
  • The older chipset may have limited driver support on the latest operating system releases

Frequently Asked Questions

Yes, the PCI Express interface provides dedicated I/O bandwidth to each of the two Gigabit Ethernet ports, so traffic on one port does not reduce throughput on the other.
Yes, the adapter supports Receive-Side Scaling on Windows and Scalable I/O on Linux, enabling efficient multi-processor network handling on both platforms.
The adapter uses a PCIe x4 physical interface conforming to the PCIe 1.0A specification. It will fit in any PCIe x4 or larger slot.
Yes, the dual-port design is well suited for link aggregation (bonding) to increase throughput or for failover configurations where one port takes over if the other loses connectivity.
The adapter is designed for use with standard Category-5 or higher Ethernet cabling for Gigabit connectivity.
