HPE 571SFP+ 

Dual‑Port 10 GbE SFP+ Gigabit Ethernet Adapter (Solarflare SFC9020)

The HPE 571SFP+ adapter is a high-performance dual-port 10 Gigabit Ethernet network card powered by the Solarflare SFC9020 chipset. Supporting two independent 10 Gbps SFP+ ports (DAC or SR fiber), it delivers up to 40 Gbps aggregate bi-directional throughput across both interfaces. Compatible with HPE ProLiant Gen8 servers, this adapter offers efficient virtualization-ready features, low CPU utilization through offloads, and excellent power efficiency, making it suitable for modern data center workloads and virtualized environments.

Features

Built around the high-performance Solarflare SFC9020 network processor, the adapter plugs into a PCIe 2.0 ×8 slot (backward compatible with ×4) and delivers line-rate 10 GbE across two SFP+ ports. It supports advanced networking standards like IEEE 802.3ae (10 GbE SR), VLAN, LACP link aggregation, jumbo frames, and LLDP. With full support for SR-IOV, RSS, interrupt coalescing, and TCP/UDP checksum offloads, the adapter optimizes CPU usage and ensures scalability in multi-core server environments

Advanced Options

It integrates seamlessly with Windows, Linux (RedHat, SUSE), and VMware platforms, offering managed teaming utilities for efficient deployment. The adapter’s validated compatibility with HPE ProLiant DL360p Gen8 and DL380p Gen8 servers ensures reliability and support from the OEM hardware and management ecosystemThis adapter is engineered for enterprise-grade performance, offering stable, low-latency 10 GbE connectivity across both ports. Each port delivers consistent 10 Gbps bidirectional data transfer, enabling exceptional throughput (20 Gb/s per port; 40 Gb/s aggregate) without busting server PCIe bandwidth Utilizing less than 7.5 W at maximum load, it maintains power efficiency—ideal for dense server environments.
