HPE 867328-B21 

Dual‑Port 10/25 GbE SFP28 Network Adapter

The HPE 867328‑B21 is a professional-grade dual‑port SFP28Network Adapter engineered to support both 10 GbE and 25 GbE connectivity. Based on the Cavium QL41401-A2G chipset, it delivers a combined theoretical bandwidth of up to 100 Gbps bi‑directional, enabling high-performance networking while offloading packet processing from the host CPU. Ideal for virtualized environments, storage traffic, and high-throughput server workloads, this adapter enhances network efficiency while reducing latency and power usage. Designed primarily for HPE ProLiant Gen8/9/10 systems, it ensures seamless integration and boosts application responsiveness in enterprise-grade deployments.

Features

This adapter plugs into a PCIe 3.0 ×8 slot and offers dual SFP28 ports capable of auto-negotiating between 10 GbE and 25 GbE speeds. It supports advanced offload technologies such as RoCE/RoCE v2 and iWARP for RDMA, along with SR‑IOV virtualization and overlay network tunneling (VXLAN, NVGRE, GRE), enabling efficient CPU utilization and accelerated traffic handling. Hardened support for jumbo frames (up to 9 KB) and comprehensive IEEE standards compliance (802.1p/Q/Qbb/Qaz/1588/etc.) make it suitable for dense virtualization, live migrations, and storage-centric workloads.

Advanced Options

Engineered for enterprise reliability, this dual‑port adapter delivers consistent performance under heavy workloads with typical power consumption of only ~8.4 W (max 9.7 W). Its Cavium QL41401 processor efficiently enables hardware offloads—such as RDMA and SR‑IOV—reducing host CPU demand and improving VM density.
