HPE701531-001

(534FLR-SFP+) Dual-Port 10 GbE FlexibleLOM Gigabit Ethernet Adapter- Refurbished

The HPE701531-001 (534FLR-SFP+) is a high-performance dual-port 10 Gb Ethernet FlexibleLOM adapter designed for Gen9 and Gen10 HPE servers. Based on the Broadcom/Avago 57810S controller, this refurbished adapter delivers reliable line-rate connectivity via two SFP+ ports. Ideal for virtualization hosts, blade servers, or high-density rack setups, it provides enhanced throughput, low latency, and robust offload features. This adapter helps modernize server networks affordably, maintaining enterprise-class performance and compatibility in ProLiant DL, ML, and Apollo platforms.

Features

This FlexibleLOM card connects via the dedicated server mezzanine slot, freeing up standard PCIe lanes while delivering dedicated 10 Gb bandwidth per port. It supports full duplex 20 Gb/s per port (40 Gb/s aggregate), with stateless offloading such as VLAN tagging, jumbo frames, TSO/LSO, RSS, and interrupt moderation. It integrates neatly into HPEProLiant Gen9/Gen10 and Apollo systems, optimizing airflow and internal cabling. With low-profile support and broad OS compatibility, it suits virtualized workloads, storage traffic, and clustered compute deployments.

Advanced Options

Engineered for consistent performance in enterprise server environments, this 534FLR-SFP+ adapter ensures stable throughput and low latency even under heavy loads. The Broadcom-based design provides industry-tested reliability and is well-supported in enterprise OS and hypervisor environments.
