Intel E810-XXVDA2 10/25Gb SFP28 PCI Express 4.0 x8 25Gbps Network Interface Card

Network-intensive workloads can stall when the connection can’t keep up, leaving you frustrated with slow transfers and wasted time. The Intel E810-XXVDA2 10/25Gb SFP28 PCI Express 4.0 x8 25Gbps Network Interface Card is a high-performance network card designed to deliver reliable 10 Gb or 25 Gb Ethernet over SFP28, giving your servers the speed and low latency needed for modern data-center tasks.

Benefits of Intel Network Card

You gain ultra-low latency thanks to iWARP/RDMA, which moves data directly between memory spaces without CPU bottlenecks. Intel® Data Direct I/O reduces the hop through system memory, cutting power use while boosting bandwidth. SR-IOV lets multiple virtual machines share the card efficiently, keeping each VM’s performance stable. Flexible Port Partitioning guarantees fair bandwidth distribution, so no single process hogs the link. All these features combine to give you a smoother, more predictable network experience that scales with your growth.

Key Features of a 25Gbps Network Card

• Ports: 2 × 10/25 Gigabit SFP28. Dual ports let you connect to high-speed fiber or copper modules for versatile deployment.
• Interface (Bus) Type: PCI Express 4.0 ×8. The latest PCIe lane delivers the bandwidth required for 25 Gbps traffic without bottlenecks.
• Data Link Protocol: 25 Gigabit Ethernet. Provides the raw speed needed for demanding applications such as AI training or high-frequency trading.
• On-chip QoS and Traffic Management. Prioritises critical packets, ensuring latency-sensitive data arrives first.
• Flexible Port Partitioning (FPP). Divides the physical adapter into virtual functions, giving each workload a guaranteed share of bandwidth.
• Virtual Machine Device Queues (VMDq). Offloads switching tasks from the hypervisor, improving overall VM throughput.
• RDMA support, RoCE v2. Enables remote direct memory access over Ethernet for near-zero-copy data transfers.
• Intel® Data Direct I/O Technology. Directly accesses processor cache, lowering latency and power consumption.
• SR-IOV capable. Allows a single physical port to appear as multiple independent devices for virtualised environments.
• Form Factor: Low-profile plug-in card. Fits easily into standard server chassis without taking up extra space.

Usages of a 25Gbps Network Card

Ideal for high-performance server farms, this card fits seamlessly into daily operations:

• Accelerating database replication between data-center nodes.
• Supporting AI model training with fast data feeds.
• Enabling low-latency financial trading platforms.
• Providing reliable storage traffic for NVMe over Fabrics.
• Powering virtual desktop infrastructure with smooth user experiences.

Why Choose Intel Network Card

Many buyers worry that a high-speed NIC will be complex to configure or that the performance gains won’t justify the cost. They also fear compatibility issues with existing servers or virtual environments.

The Intel E810-XXVDA2 removes these doubts. Its PCIe 4.0 ×8 interface guarantees full 25 Gbps throughput, while built-in SR-IOV, VMDq and FPP make virtualisation straightforward and efficient. The combination of iWARP/RDMA and DDIO ensures low latency and power efficiency, delivering the speed you need without the usual headaches.
