HP FlexFabric 701531-001 534FLR Dual Port 10Gbps PCI-e 2.0 laptop replacement part

HP FlexFabric 534FLR Dual Port 10Gb Adapter

The HP FlexFabric 534FLR (part 701531-001) is a dual port 10Gb Ethernet PCIe adapter designed for HP ProLiant Gen8 and Gen9 rack and tower servers. It provides two SFP+ cages for high-speed networking in enterprise environments. SFP+ transceivers are not included and must be sourced separately. This replacement part suits administrators upgrading or repairing server connectivity.

Sustained throughput on PCIe 2.0 x8

The adapter uses a PCIe 2.0 x8 interface to deliver reliable throughput for continuous workloads such as virtualization, iSCSI and FCoE storage traffic. Dual 10GbE ports maintain consistent bandwidth under load with support for SR-IOV and network offload engines. Advanced VLAN and QoS features help manage traffic priority during extended operation. Low profile form factor fits dense rack deployments without airflow compromise.

Practical limits of PCIe 2.0 x8 and SFP+

PCIe 2.0 x8 bandwidth caps maximum theoretical throughput below what a single 10GbE port can saturate in both directions simultaneously. Each port requires a compatible SFP+ transceiver and cable, which are not supplied, so distance and media type depend on those choices. The adapter is qualified only for listed HP ProLiant Gen8 and Gen9 servers; other platforms are not supported. Buyers needing more than two ports or a newer PCIe generation must select a different adapter.
