E810-XXVDA2 25G Dual-Port 10Gb Fiber Network Card

The E810-XXVDA2 is a dual-port fiber network card listed by Newegg with “25G” and “10Gb” speed labels, suited to users adding fiber connectivity to a compatible system; confirm the speed and interface requirements for your setup.

Recommended For

• Server and NAS operators moving large files between systems or storage over a 10/25GbE SFP28 network; the card supports two ports and Intel lists iSCSI, NFS, and RDMA capabilities.
• Virtualization-host builders who need multiple network interfaces for virtual machines or want to configure SR-IOV; Intel lists VMDq and SR-IOV support for the adapter.
• Home-lab and Proxmox users building a 10/25GbE link between servers, storage, or a compatible switch, especially when they can use SFP28 DACs or optics and have adequate PCIe bandwidth.
• Network or storage teams testing Ethernet RDMA for workloads that can use iWARP or RoCEv2; Intel lists both technologies for this adapter, so the surrounding systems and network must also be configured for the intended RDMA setup.

Real-World Use Scenarios

• For a server or NAS moving large files to another high-speed system, the card can provide a faster wired link; the actual transfer speed depends on the other device, switch, cabling, and storage.
• In a Proxmox or other virtualization host, it can connect the server to a high-speed network for VM and host traffic; the benefit depends on having compatible network equipment and configuring the host and guests appropriately.
• For a homelab server, NAS, or workstation with compatible SFP28 networking, the two ports can support separate high-speed connections—for example, to a switch and another system—without relying on a single network port.
• In a DIY router or firewall build, it can add high-speed network interfaces for WAN or LAN connections; the system still needs suitable PCIe capacity, cooling, drivers, and compatible SFP28 networking.
• When adding a 25GbE-capable card to an existing 10GbE setup, it can connect at a supported lower link speed, letting the system join the current network while leaving room for a later compatible upgrade.
