Intel XXV710-DA1 25GbE PCIe 3.0 x8 SFP28 Network Adapter

SKU CH-8FXN-WXCPR

Adds a 25 Gbps SFP28 port over PCIe 3.0 x8 for high-throughput server networking

  • 25 Gbps throughput over a single SFP28 port
  • PCIe 3.0 x8 interface for high-speed data transfer
  • Broad OS support including Windows Server 2008 R2 and FreeBSD 10.3
  • Advanced virtualization with SR-IOV and Intel VT-c
  • Intelligent offloads reduce CPU load for TCP/IP and UDP/IP

Intel XXV710-DA1 25GbE Adapter for Enterprise

The Intel XXV710-DA1 is a 25GbE network adapter built for enterprise servers and data centres. It delivers a single 25 Gigabit SFP28 port over a PCIe 3.0 x8 interface. The card targets bandwidth-intensive workloads such as virtualization, cloud computing and storage traffic. Broad OS support simplifies deployment across mixed environments.

Installation Notes and Common Issues

The adapter installs into any PCIe 3.0 x8 or wider slot and uses a standard SFP28 transceiver. Ensure the transceiver and cabling match the required reach and fibre type. Driver availability should be confirmed for the specific OS version before deployment. A frequent issue is neglecting to enable SR-IOV or VMDq in the BIOS and driver for full virtualization offload.

PCIe 3.0 x8 and SFP28 Practical Limits

The PCIe 3.0 x8 electrical interface provides sufficient bandwidth for the 25GbE line rate with headroom for protocol overhead. The SFP28 port accepts compatible 25G optics or direct-attach cables up to their rated distance. Throughput scales with the negotiated link speed and the host system's ability to sustain queue processing. Unsupported operating systems will lack driver optimisation for advanced offloads.

Questions about this item

How can I verify the Intel XXV710-DA1 is operating at 25Gbps after installation?

Check the port transmission speed indicator on the bracket; it shows the active link rate. In the OS, confirm the adapter negotiates 25 Gbps and that link/activity LEDs blink during traffic.

What ships with the XXV710-DA1 and what must I source separately?

The adapter includes the PCIe 3.0 x8 card with one SFP28 port. You must purchase a compatible 25G SFP28 transceiver module and fibre or DAC cable separately.

Which version of the XXV710-DA1 should I choose for a Windows Server 2008 R2 host?

The single SKU XXV710-DA1 supports Windows Server 2008 R2 and FreeBSD 10.3 and 11. No alternative capacities or versions exist for this model.
