Network adapter INTEL NIC E830XXVDA2 25Gb, 2 x SFP28 ports

INTEL NIC E830XXVDA2 is a PCIe network adapter that provides dual 25Gb connections via two SFP28 ports. Designed for use in servers and high-performance workstations, the card delivers multi-gigabit throughput suitable for virtualization, storage networking and general data center traffic. The adapter supports industry-standard SFP28 optical and direct-attach modules, low-latency packet processing and straightforward integration into existing Ethernet infrastructures to expand network bandwidth and capacity.

Advantages

The adapter offers two independent 25Gb ports for aggregated bandwidth or redundant links, delivering hardware-level performance and lower CPU overhead compared with software-based network solutions. Its compatibility with standard SFP28 transceivers and direct attach copper modules simplifies deployment in mixed-fiber and copper environments. Built for continuous operation, the card includes features that help reduce latency and maintain throughput under heavy loads.

Suitable for

• Virtualization hosts requiring high network throughput
• High-performance storage networks (NAS, SAN)
• Data center top-of-rack and aggregation connectivity
• Low-latency trading platforms and real-time applications
• Server upgrades to increase uplink capacity

Key specifications

• Interface: PCI Express (PCIe) for server and workstation expansion
• Port configuration: 2 x SFP28 ports supporting 25Gb operation
• Supported media: SFP28 optical transceivers and direct-attach copper (DAC) modules
• Performance: Multi-gigabit throughput with low-latency packet processing
• Offloads: Hardware offload capabilities to reduce host CPU utilization
• Form factor: Low-profile bracket compatibility for 1U/2U servers (check chassis slot height)
• Network protocols: Standard Ethernet framing and common data center networking features

How to use

Install the INTEL NIC E830XXVDA2 into an available PCIe slot on a powered-down server or workstation, secure the bracket and connect appropriate SFP28 transceivers or DAC cables to the required network switches or transceivers. After booting, install or update the operating system drivers to the recommended Intel driver release for full feature support and enable any required network settings such as link aggregation, VLAN tagging or SR-IOV through the host OS or management tools.

Usage recommendations

For optimal performance, use high-quality SFP28 modules or certified DAC cables rated for 25Gb operation, ensure the server BIOS and firmware are up to date, and configure appropriate offload and interrupt moderation settings. When deploying in dense rack environments, verify airflow and card cooling to maintain sustained throughput.
