The ProLab XXV710-DA2 Dual-port 25GbE SFP28 Network Adapter is an enterprise-class high-performance Ethernet solution engineered for data center infrastructures, virtualization platforms, cloud environments, enterprise storage systems, and high-bandwidth computing deployments requiring scalable 25 Gigabit network connectivity. Built around the Intel XL710-BM2 Ethernet controller architecture, the adapter delivers dual-port 25GbE SFP28 connectivity through a PCI Express Gen3 x8 interface, enabling low-latency, high-throughput communication for modern enterprise workloads. The card is particularly suited for virtualization clusters, hyper-converged infrastructure, software-defined storage environments, AI and analytics platforms, media production systems, and cloud-scale server deployments where advanced virtualization support and consistent high-speed network performance are essential operational requirements.
The adapter operates over a PCI Express 3.0 x8 interface, providing sufficient upstream bandwidth to efficiently support simultaneous dual-port 25GbE traffic while minimizing bus-level congestion during sustained workloads. Powered by the Intel XL710-BM2 controller, the card is optimized for enterprise networking environments requiring scalable packet processing, virtualization-aware traffic acceleration, and hardware-assisted networking functions. The adapter incorporates two SFP28 cages supporting both Direct Attach Copper (DAC) Twinaxial cabling and optical transceiver modules, enabling flexible deployment across short-range rack-level interconnects and long-distance optical networking infrastructures.
Each network interface supports multi-speed Ethernet operation including 25GbE, 10GbE, and 1GbE depending on transceiver and cable configuration. Optical connectivity supports 25GBASE-SR and 25GBASE-LR transceivers for high-speed fiber deployments across multimode and single-mode optical infrastructures. Support for 25GBASE-CR DAC cabling enables low-latency and power-efficient server interconnects commonly used within top-of-rack architectures, clustered virtualization hosts, and high-density data center environments. The adapter also supports 10GBASE-SR/LR optical transceivers and 10GbE SFP+ DAC configurations, allowing backward compatibility with existing 10GbE network infrastructures during phased infrastructure upgrades.
The networking architecture incorporates automatic Forward Error Correction (FEC) handling, including support for no-FEC, BASE-R FEC, and RS-FEC modes to ensure compatibility across CA-N, CA-S, and CA-L cable environments. This functionality improves link reliability and signal integrity within high-speed 25GbE deployments while enabling compatibility with a broad range of enterprise networking hardware and cabling infrastructures. Support for SFP28 direct attach Twinaxial cabling extends up to 5 meters, making the adapter particularly suitable for low-latency server-to-switch deployments within high-density rack environments.
Enterprise virtualization and software-defined networking support form a core component of the adapter architecture. Hardware-assisted network virtualization offloads support VxLAN, GENEVE, NVGRE, MPLS, and VxLAN-GPE with Network Service Headers (NSH), enabling efficient encapsulation and segmentation of virtualized traffic while reducing CPU overhead on host systems. These capabilities improve scalability and operational efficiency within cloud infrastructures, virtualization clusters, software-defined storage environments, and containerized application platforms where overlay networking and virtual network abstraction are heavily utilized.
Support for multiple interrupt mechanisms including INTA, MSI, and MSI-X further improves packet processing efficiency and scalability within multi-core enterprise servers handling intensive network workloads. Combined with Intel’s enterprise Ethernet architecture, these features enable low-latency communication, optimized throughput distribution, and efficient queue management across demanding networking environments.
Broad operating system compatibility enables the adapter to integrate seamlessly into heterogeneous enterprise infrastructures. Windows support includes Windows 10 and Windows 11 workstation environments alongside Windows Server 2012, 2012 R2, 2016, 2019, and 2022 platforms. Linux compatibility extends across Red Hat Enterprise Linux 8.7 and 9.1, SUSE Linux Enterprise Server 12 SP5 and 15 SP4, Ubuntu 20.04 LTS and 22.04 LTS, Debian 11, and FreeBSD 12.3 and 13. This extensive operating system support allows deployment across virtualization hosts, enterprise storage systems, cloud infrastructure nodes, industrial platforms, and professional workstation environments operating within mixed operating system ecosystems.
From a physical deployment perspective, the adapter measures 167 mm x 69 mm and ships with a pre-installed full-height bracket for standard rackmount server and workstation installations. An included low-profile bracket enables compatibility with compact chassis and space-constrained enterprise systems. The compact dual-port SFP28 architecture enables high-bandwidth network expansion while maintaining efficient utilization of PCIe expansion resources within enterprise servers and virtualization hosts.
The adapter is optimized for enterprise thermal environments with airflow requirements tailored to both DAC and optical deployments. DAC configurations require approximately 100 LFM airflow at 55°C, while SR optical deployments require approximately 250 LFM airflow at the same ambient temperature. These thermal specifications ensure stable operation within high-density data center and enterprise rackmount infrastructures operating under sustained network loads.
Power efficiency remains an important characteristic of the adapter architecture, with maximum power consumption rated at approximately 11.8 watts despite supporting dual-port 25GbE connectivity. Integrated LED indicators provide real-time visibility into link status, network activity, and negotiated connection speeds. Dedicated indicators differentiate between 25Gbps and 10Gbps operation, simplifying deployment verification, diagnostics, and infrastructure troubleshooting procedures within enterprise environments.
Environmental reliability further supports deployment within enterprise and industrial infrastructures. Operating temperature support ranges from 0°C to 55°C, while storage tolerance extends from -40°C to 70°C. Humidity tolerance supports up to 90% non-condensing relative humidity at 35°C, enabling dependable operation within controlled data center environments and industrial networking platforms. Compliance with CE, FCC, and RoHS certifications confirms adherence to internationally recognized standards for electromagnetic compatibility, environmental compliance, and commercial system integration requirements.
Overall, the ProLab XXV710-DA2 Dual-port 25GbE SFP28 Network Adapter provides a scalable and professionally engineered Ethernet connectivity platform for enterprise systems requiring high-bandwidth 25GbE networking, advanced virtualization acceleration, and flexible SFP28 deployment capability. Its Intel XL710-BM2 controller architecture, PCIe Gen3 x8 interface, support for optical and DAC connectivity, enterprise virtualization offloads, and broad operating system compatibility make it well suited for cloud infrastructures, virtualization environments, enterprise storage systems, AI and analytics platforms, and high-performance server deployments where dependable ultra-high-speed network communication is essential.
