Product information

Description

The HP 535FLR-T is a dual‑port 10Gb Ethernet network adapter in a card form factor designed for PCI Express mezzanine/FLR slots on compatible servers. It provides two 10 Gigabit Ethernet ports and a PCI Express host interface, delivering high throughput for virtualized environments, storage networks and latency‑sensitive applications. The adapter is intended to integrate with server platforms that support FLR mezzanine cards and to provide reliable, high‑speed connectivity for multi‑tenant and clustered deployments.

Advantages

The adapter offers dual 10Gbps ports to support aggregated bandwidth and redundancy, reducing network bottlenecks for demanding workloads. Its PCI Express FLR form factor allows low-profile integration into compatible server mezzanine slots while conserving standard I/O bay space. The HP 535FLR-T supports features common to enterprise network cards such as offload capabilities and driver support for virtualization, which help lower CPU overhead and improve overall network performance.

Suitable for

Virtualized hosts running multiple VMs where high network throughput and offloading are required
Database and application servers that need low-latency, high-bandwidth connections
Storage networks and clustered systems requiring multiple 10Gb links or link aggregation
Data center or rack servers with FLR/mezzanine-compatible PCIe slots

When it may not be suitable

This adapter requires a server platform that supports the FLR mezzanine/PCIe card form factor; it will not fit in standard full-height PCIe slots without the appropriate mezzanine slot. It is optimized for 10Gb Ethernet environments, so it may be unnecessary for systems that only require 1Gb connectivity or where lower-speed NICs suffice for the workload.

Key specifications

Interface: PCI Express (mezzanine/FLR form factor)
Network speed: 10 Gigabit Ethernet per port
Ports: 2 external 10Gb Ethernet ports
Form factor: Low-profile server mezzanine/FLR card
Typical use: High-throughput, virtualized and storage network environments

How to use

Install the HP 535FLR-T into a compatible server mezzanine or FLR slot following the server manufacturer’s instructions. After physical installation, ensure the server BIOS and firmware are updated to support the card, then install the appropriate network drivers provided by the server vendor or HP. Configure link settings, VLANs, teaming or offload options in the operating system or hypervisor network management tools according to your network design. Verify link negotiation and throughput using standard network diagnostics.

What to consider before purchase

Confirm your server chassis and motherboard support FLR/mezzanine PCIe card installation
Verify the operating system and hypervisor have compatible drivers for the adapter
Ensure your network infrastructure (switches, transceivers, cabling) supports 10Gb links
Consider whether dual 10Gb ports match your redundancy or aggregation requirements

Usage recommendations

For best performance, pair the adapter with compatible 10Gb switches and use certified SFP+ transceivers and appropriate cabling. Keep server firmware and network drivers up to date to maintain stability and leverage offload features for virtualized workloads.
