Ports & Speed 2 Ports - 25/10/1GbE

  • Dual 25 GbE ports for high-density server connectivity
  • PCIe 4.0 x8 interface delivers fast host bandwidth
  • Dynamic Device Personalization accelerates protocol traffic with less CPU load
  • iWARP and RoCEv2 support enables low-latency RDMA transfers
  • IEEE 1588 Precision Time Protocol provides accurate network synchronisation

Dual-port 25GbE server adapter

The Intel E810XXVDA2BLK is a dual-port SFP28 network card built for servers that need 25/10/1GbE connectivity over optical fibre. It plugs into a PCIe 4.0 x8 slot and measures 167 mm by 68 mm, fitting standard full-height brackets. Target users are IT teams deploying high-density cloud, NFV, storage or HPC-AI workloads.

Sustained throughput with hardware offloads

Under continuous load the adapter uses Dynamic Device Personalization to accelerate protocol-specific traffic and reduce CPU overhead. Application Device Queues isolate critical flows for lower latency and higher throughput, while iWARP and RoCEv2 RDMA support moves data directly between memory regions. IEEE 1588 Precision Time Protocol hardware assists keep clocks aligned across the cluster.

Verify slot, optics and driver support

Confirm the host has a free PCIe 4.0 x8 or wider slot and that the chassis can accommodate a full-height card. Source SFP28 optics or direct-attach cables rated for 25GbE or 10GbE operation. Ensure the operating system or hypervisor includes a driver that enables ADQ, DDP and PTP features for the E810 controller.

Questions about this item

How much power and heat does the Intel E810XXVDA2BLK produce when running at 25 GbE all day?

The adapter uses a PCIe 4.0 x8 interface and dual SFP28 ports rated at 25/10/1 GbE per port; typical power draw and thermal output depend on the SFP28 modules installed and server airflow.

What must I already own so the Intel E810XXVDA2BLK works — slot, cables, transceivers?

You need a PCIe 4.0 x8 slot (mechanical x16 works), two SFP28 transceivers or DACs, and matching fibre or copper cables; the card itself is 167 mm x 68 mm full-height.

Will the Intel E810XXVDA2BLK slow down if I keep my older PCIe 3.0 server and 10 GbE switches?

The card negotiates down to PCIe 3.0 x8 and 10/1 GbE link speeds automatically, so it functions with older slots and switches at their maximum rates.
