Intel Ethernet Adapter E810-XXVDA4 25 Gigabit 4x10Gb/25Gb SFP28 Adapter

A slow, congested network can cripple data-centre workloads, causing latency spikes and wasted compute cycles. The Intel Ethernet Adapter E810-XXVDA4 25 Gigabit 4x10Gb/25Gb SFP28 Adapter delivers four high-speed ports that let you move massive data sets quickly and reliably, making it the ideal solution for modern, performance-driven environments.

Intel Ethernet Adapter E810-XXVDA4 25 Gigabit 4x10Gb/25Gb SFP28 Adapter - solving bandwidth bottlenecks

Enterprises often struggle with limited bandwidth when consolidating servers or running virtualised workloads. This creates delays, higher latency and reduced efficiency, especially in high-frequency trading, AI training, or large-scale storage clusters. The Intel Ethernet Adapter E810-XXVDA4 25 Gigabit 4x10Gb/25Gb SFP28 Adapter removes those constraints by providing four independent 10 Gb/25 Gb SFP28 ports, each capable of handling intense traffic loads. With built-in iWARP/RDMA, SR-IOV, and DDIO, the card bypasses the CPU for data movement, cutting latency and freeing processing power for your critical applications.

Usages of Intel Ethernet Adapter E810-XXVDA4 25 Gigabit 4x10Gb/25Gb SFP28 Adapter

Designed for demanding data-centre scenarios, this adapter fits a range of use cases:

• High-performance computing clusters that need low-latency interconnects.
• Virtualised server farms where SR-IOV separates traffic for multiple VMs.
• Storage arrays requiring fast, reliable fibre connections.
• Financial trading platforms that demand sub-microsecond response times.
• AI and machine-learning workloads that move large data sets between GPUs.

Benefits of Intel Ethernet Adapter E810-XXVDA4 25 Gigabit 4x10Gb/25Gb SFP28 Adapter

You gain dramatically lower latency, letting time-sensitive applications respond faster and improve overall throughput. The adapter’s offload technologies free CPU cycles, so your servers can focus on processing rather than moving data. With SR-IOV and Flexible Port Partitioning, you can safely share a single physical card across many virtual machines, simplifying hardware management while maintaining performance isolation. Power efficiency rises thanks to DDIO, reducing operating costs and heat output. Finally, the four high-speed SFP28 ports give you the flexibility to scale bandwidth as your workload grows, protecting your investment for years to come.
