Description
Description
Overview
The Intel E810XXVDA4BLK is a four-port 25 Gigabit Ethernet adapter designed for servers that require higher bandwidth than traditional 10 Gigabit cards. Each SFP28 port supports speeds of 25, 10, or 1 Gigabit, allowing flexible connectivity options that can adapt to current network setups and future upgrades. Installed in a PCIe 4.0 x16 slot, it delivers sufficient bus bandwidth to run all four ports at full line rate, making it suitable for demanding enterprise environments.
Key features
- Four SFP28 ports capable of operating at 25, 10, or 1 Gigabit Ethernet speeds for versatile network compatibility
- PCIe 4.0 x16 interface ensures ample bandwidth to support full line rate on all ports simultaneously
- Intel Ethernet Controller E810 efficiently manages packet processing and offloads CPU tasks to improve overall system performance
- RDMA support with RoCE v2 and iWARP reduces latency and CPU load, enhancing data transfer for storage and computation applications
- SR-IOV and Virtual Machine Device Queues provide dedicated network paths for virtual machines and containers, ensuring consistent performance
- On-chip Quality of Service and traffic management features allow precise control over bandwidth allocation and prioritization of critical services
- Compatible with both copper direct attach cables and fiber transceivers, offering flexibility in cabling based on rack layout and budget
- Full height bracket fits standard server chassis, simplifying installation in enterprise racks

Connectivity and compatibility
This adapter supports a range of network connections through its four SFP28 cages, which accept both copper direct attach cables and fiber optic transceivers. This flexibility allows integration into existing network infrastructures without requiring immediate cabling changes. The PCIe 4.0 x16 slot interface ensures compatibility with modern server motherboards that support high-speed data transfer, making it a strong fit for virtualization hosts, hyperconverged clusters, and high-performance computing nodes.
Performance and reliability
The Intel Ethernet Controller E810 at the core of this card optimizes throughput and reduces latency by offloading packet processing from the CPU. RDMA support with RoCE v2 and iWARP further accelerates data movement between servers, which is critical for applications like NVMe over Fabrics storage and large database clusters. Virtualization features such as SR-IOV and Virtual Machine Device Queues ensure that network performance remains stable and predictable even under heavy host workloads.
Ideal uses and environments
This Ethernet card is well suited to enterprise environments that demand reliable 25 Gigabit connectivity, including virtualization hosts, hyperconverged infrastructure, and high-performance computing setups. Its ability to handle multiple speeds and cable types makes it adaptable to evolving network requirements, while its advanced traffic management features help maintain service quality in busy data centers. Organizations looking to upgrade from 10 Gigabit networks without replacing hardware will find this card a practical and future-proof choice.

All available options and final pricing are clearly shown before payment so you can choose the service that best fits your needs.
Deliveries are handled by major carriers such as USPS, UPS, and FedEx. Estimated delivery times are displayed at checkout and may vary depending on service level and location. Please note that these are estimates and can be affected by weather, holidays, or carrier volume. Once your order ships, you’ll receive a tracking number for real-time updates from pickup to final delivery.
Providing an accurate shipping address helps prevent delays, and changes may be limited once the order has been dispatched. P.O. boxes are supported only when permitted by the selected carrier. Packaging and handoff are optimized to protect items during transit, though oversized or high-weight products may require special handling. All shipping methods and any related constraints are clearly shown during checkout.
Returns and refunds
Returns and refunds
Returns are accepted within 30 days of delivery. Items must be unused, in the same condition received, with tags, manuals, accessories, and original, unaltered packaging. Any item kept will be deducted from the refund. Start a return by sending us an email. Items sent back without approval may be refused or returned to the sender.
Some items are not returnable: opened TVs/combos/monitors 37″+, opened computers or software, electronic downloads, opened consumables (film, paper, bulbs, media, ink), custom or modified computers, special-order or “nonreturnable” items, submerged underwater gear, and opened educational media.
After inspection, refunds are issued to the original payment method; allow 5–7 business days for the credit to post. Shipping, handling, customs duties, and import taxes are nonrefundable. If an item is used, incomplete, or not in original condition, a 30% restocking fee may apply. Direct exchanges are not offered; purchase the replacement and return the original for a refund.
Product warranty
Product warranty
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.
