HPE544FLR-QSF

Dual-Port 10/40 Gb InfiniBand/Gigabit Ethernet Adapter (FlexibleLOM, Refurbished)

The HPE544FLR-QSF dual-function adapter offers two QSFP-based ports capable of running as InfiniBand FDR (56 Gb/s) or Ethernet QDR (40 Gb/s). Designed for HPEGen8 and Gen9 servers, this FlexibleLOM mezzanine card fits directly into server fabric, eliminating the need for PCIe expansion. Ideal for HPC clusters, storage fabrics, and low-latency networking, it supports high throughput and hardware offload capabilities. As a refurbished unit, it's a cost-effective choice for boosting interconnect capacity in enterprise and compute-dense environments.

Features

Based on Mellanox ConnectX-3 Pro technology, this adapter provides ultra-low latency InfiniBand or high-bandwidth Ethernet connectivity depending on configuration. Each port runs at up to 56 Gb/s FDR or 40 Gb/s Ethernet, switching modes via BIOS utility commands Compatible with HPEProLiant BL, DL, XL, and SL servers with FLR slots, it enables flexible network topology deployment without consuming PCIe resources. Advanced offload features support RDMA over Converged Ethernet (RoCE), QoS tagging, jumbo frames, low latency packet routing, and virtualization acceleration×ideal for HPC, big data, and enterprise storage fabrics.

Advanced Options

This refurbished adapter delivers enterprise-grade reliability and performance in demanding environments. With support for InfiniBand FDR and Ethernet QDR, it seamlessly adapts to interconnect or high-speed LAN roles. Mellanox silicon and hardware offloads minimize CPU load and deliver sub-microsecond latency across clusters and storage nodes
