P08458-B21 Intel E810-XXVDA4 Ethernet 10/25Gb 4-port SFP28 Adapter for HPE

The P08458-B21 Intel E810-XXVDA4 Ethernet 10/25Gb 4-port SFP28 Adapter for HPE is a premium, high-density networking interface card designed to meet the rigorous data transmission demands of modern enterprise, cloud, and telecommunications environments.

Featuring a high-density quad-port configuration utilizing Small Form-factor Pluggable 28 (SFP28) technology, this adapter provides maximum throughput scaling and flexible bandwidth aggregation per physical compute node. It delivers the ultra-low latency pathing required to support dense containerized application structures, high-frequency transactional data streams, and hyper-converged virtualization clusters.

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 across the network fabric.

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 quad-port SFP28 architecture grants network architects exceptional structural flexibility, enabling the concurrent 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.

Furthermore, the P08458-B21 is heavily optimized for modern software-defined data centers (SDDCs) and next-generation multi-tenant cloud ecosystems. It features extensive support for advanced network virtualization and overlay tunneling technologies, which enhance packet routing efficiency and isolate virtual client boundaries.
