HPE867328-B21

Dual-Port 10/25 GbE SFP28 Network Adapter

The HPE867328-B21 is a professional-grade dual-port SFP28Network Adapterengineered 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 HPEProLiant 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.
