P08443-B21 Intel E810-XXVDA2 Ethernet 10/25Gb 2-port SFP28 Adapter for HPE

The P08443-B21 Intel E810-XXVDA2 Ethernet 10/25Gb 2-port SFP28 Adapter for HPE is a premier, high-bandwidth networking solution designed to handle the rigorous data demands of modern enterprise, cloud, and telecommunications environments.

Featuring dual physical ports utilizing Small Form-factor Pluggable 28 (SFP28) technology, this network interface card delivers exceptional 10Gb or high-speed 25Gb Ethernet connectivity per port. It provides the essential throughput scaling and ultra-low latency pathing required to support high-density virtualization, large-scale cloud architectures, and intense high-frequency transactional data streams.

Built upon the advanced Intel Ethernet 800 Series controller architecture, this adapter introduces powerful hardware optimization features such as Application Device Queues (ADQ) and Dynamic Device Personalization (DDP). These capabilities allow the network interface to intelligently prioritize critical application traffic, streamline packet processing, and significantly reduce latency fluctuations.

This network interface card leverages a high-speed PCI Express (PCIe) bus interface, ensuring seamless bidirectional communication and preventing data line starvation between the network edge and the processor complex.

The dual-port SFP28 architecture grants network architects structural flexibility, enabling the deployment of short-range (SR) or long-range (LR) optical transceivers, as well as cost-effective twinaxial Direct Attach Copper (DAC) cables for top-of-the-rack switch connections. This dual-port layout is perfect for implementing network zoning, secure link aggregation (NIC teaming) for bandwidth optimization, and automated failover pathways to preserve high-availability configurations.

Furthermore, the P08443-B21 is heavily optimized for modern software-defined data centers (SDDCs) and next-generation containerized application fabrics. It features extensive support for advanced network virtualization and overlay tunneling technologies, which enhance packet routing efficiency within multi-tenant cloud ecosystems.

25Gb SFP28 interfaces offer a 2.5x increase in bandwidth over traditional 10Gb ports while maintaining a similar physical footprint and power profile. Additionally, 25Gb migration pathways align perfectly with PCIe Gen4 server architectures, providing higher throughput and reduced virtualization performance bottlenecks at a highly cost-effective price-to-performance ratio.

Yes, the Intel E810-AM2 silicon architecture natively features concurrent support for both iWARP and RoCE v2 protocols. This unique dual-RDMA compatibility grants network engineers maximum flexibility when configuring low-latency storage fabrics, high-performance computing clusters, or fast live migrations of virtual environments.

To secure the intricate electrical components against static damage and physical impact during transit, every adapter is packaged inside a specialized multi-layer ESD (Electrostatic Discharge) shielding enclosure with custom shock-absorbent foam cushioning. Shipments are managed through top-tier international logistics networks, ensuring priority tracking and arrival within 3 to 5 business days globally.

No, the P08443-B21 adapter operates natively without additional software licensing fees. It is fully integrated with standard HPE ProLiant management systems and supports native driver execution across major enterprise operating systems, including VMware vSphere, Microsoft Windows Server, and Red Hat Enterprise Linux.
