Intel E810XXVDA4OCPV3

Overview

The Intel E810XXVDA4OCPV3 is a high-performance network adapter designed for servers, featuring four SFP28 ports that support both 10 and 25 Gigabit Ethernet speeds. Built around the Intel Ethernet E810 controller and equipped with a PCIe 4.0 interface, it ensures fast data transfer and low latency, making it well suited for demanding data center environments, virtualized workloads, and high-traffic applications.

This adapter supports advanced networking technologies like RDMA over Converged Ethernet (iWARP and RoCEv2), which reduce CPU load by enabling direct memory access for storage and messaging tasks. Its OCP 3.0 form factor fits modern rack-mount servers, providing flexibility with both copper and fiber cabling options.

Key features

• Four SFP28 ports that allow flexible 10 GbE or 25 GbE connections to match existing or upgraded network infrastructure
• PCIe 4.0 interface that accelerates data movement between the network adapter and host server for improved responsiveness
• Intel Ethernet E810 controller delivers consistent low latency and high throughput for demanding workloads
• RDMA support via iWARP and RoCEv2 protocols reduces CPU overhead by enabling direct memory access for data transfers
• Virtualization enhancements including Single Root I/O Virtualization (SR-IOV) and Virtual Machine Device Queues (VMDq) provide dedicated bandwidth slices to virtual machines
• On-chip quality of service (QoS) and traffic management tools allow administrators to prioritize critical network streams effectively
• Compatibility with both copper and fiber SFP28 modules offers deployment flexibility without the need for extensive re-cabling
• OCP 3.0 form factor ensures clean installation in modern server racks, optimizing space and airflow

Connectivity and compatibility

This network adapter supports a wide range of server environments thanks to its OCP 3.0 form factor and flexible cabling options. It works seamlessly with both copper and fiber SFP28 transceivers, allowing integration into existing 10 GbE setups or new 25 GbE deployments without major infrastructure changes. The PCIe 4.0 interface ensures compatibility with modern server motherboards, providing ample bandwidth for high-speed networking tasks.

Performance and reliability

Designed for data centers and enterprise environments, this adapter delivers reliable performance under heavy network loads. The Intel Ethernet E810 controller optimizes throughput and minimizes latency, while RDMA support offloads data transfer tasks from the CPU, improving overall system efficiency. Virtualization features ensure stable and predictable network performance for multiple virtual machines running simultaneously.

Ideal uses and environments

This network adapter is a strong choice for cloud platforms, enterprise server farms, and telecom edge deployments where high-speed connectivity and efficient resource management are critical. It fits well in setups that require upgrading from 10 GbE to 25 GbE without disrupting existing cabling, and it supports virtualized environments that demand dedicated bandwidth and low latency. IT professionals managing dense server racks will appreciate its compact OCP 3.0 design and flexible deployment options.

We act solely as a reseller. Any product warranty is provided and administered by the manufacturer, not by our store. That means eligibility, coverage, and outcomes are determined by the manufacturer’s policy for each brand and model. Before purchasing, we recommend reviewing the warranty terms on the manufacturer’s website or in the product documentation to confirm what is covered and for how long.

If you need warranty service, please file the claim directly with the manufacturer. They may require proof of purchase, the product serial number, original packaging, photos, or basic troubleshooting. Some brands ask you to register the product or obtain a case number before shipping it for repair or replacement. We don’t submit or approve claims, but we can point you to the correct support links and contact details.

Keep your invoice and packaging in a safe place, and report any functional issues to the manufacturer as soon as they appear. If you’re unsure whether a problem is covered, the manufacturer’s support team can confirm next steps and timelines. While we cannot intervene in decisions or outcomes, we’re happy to provide purchase documentation or guidance so you can move through the warranty process smoothly.
