Network adapter INTEL E810-XXVDA4 PCIe 4.0 x16 Low Profile 10/25 Gigabit SFP28

INTEL E810-XXVDA4 PCIe 4.0 x16 Low Profile 10/25 Gigabit SFP28 is a server-grade network adapter designed to deliver multi-rate 10/25 GbE connectivity through SFP28 ports. Built for installation in servers and high-performance workstations, this adapter supports low-latency packet handling and hardware offloads that improve throughput for virtualization, storage networking and other demanding network workloads.

Advantages

The adapter offers PCIe 4.0 x16 bandwidth for high-throughput environments and a low-profile form factor for compatibility with compact server enclosures. Hardware offload capabilities reduce CPU overhead for packet processing and virtualization tasks, while the SFP28 multi-rate ports allow use with 10G or 25G optics for flexible deployment. Designed for reliability and consistent latency, it supports high-bandwidth links with efficient power use suitable for data center and enterprise deployments.

Suitable for

• Data center aggregation, top-of-rack and server NIC upgrades
• Virtualization hosts and hyper-converged infrastructure
• High-performance storage networks and backup servers
• Low-latency trading, database clustering and HPC interconnects
• Edge and compact server systems requiring low-profile adapters

Key specifications

• Interface: PCIe 4.0 x16 physical connection
• Form factor: Low profile bracket compatible with rack and compact servers
• Link rates: Supports 10 Gigabit and 25 Gigabit Ethernet (multi-rate)
• Ports: SFP28 optical ports (number of ports as provided by the vendor)
• Latency: Low-latency packet processing with hardware acceleration
• Offload features: Packet, checksum and virtualization offloads to reduce host CPU load
• Target environments: Server and workstation network deployments in data centers and enterprise IT

How to use

Install the adapter into an available PCIe 4.0 x16 slot or a compatible slot that meets system mechanical and lane requirements, secure the low-profile bracket and connect SFP28 optics or Direct Attach Cables (DAC) to the ports. Ensure the host firmware and operating system have appropriate driver support for the INTEL E810 series and enable any desired offload or virtualization features through the OS or hypervisor network settings. Verify link negotiation and speed settings after connecting to the network switch or transceiver.

Usage recommendations

For optimal performance, use certified SFP28 optics or DACs rated for 10G/25G operation, keep firmware and drivers up to date, and configure flow control and offload settings according to workload characteristics. In dense deployments, monitor thermal and power constraints in the host chassis and verify compatibility with the server vendor’s supported hardware list.
