Adaptador de red HP Enterprise FlexFabric 10Gb 534FLR-SFP+ Dual Port SFP+

HP Enterprise FlexFabric 10Gb 534FLR-SFP+ Dual Port SFP+ is a dual-port 10 Gigabit Ethernet network adapter engineered for enterprise server environments. The card provides two SFP+ ports for 10Gb connectivity using compatible optical or DAC modules, and is designed to fit FLR (FlexibleLOM or FLR-specific) slots in supported HP Enterprise servers. It targets high-throughput, low-latency network tasks common in virtualization, storage traffic and data center workloads, enabling increased network bandwidth and improved I/O performance for scale-up or scale-out deployments.

Advantages

The adapter delivers dual 10Gb SFP+ ports to support aggregated bandwidth and redundant links, reducing network bottlenecks. It supports offload capabilities and hardware features typical of FlexFabric designs to lower CPU overhead and improve latency for virtualized network functions. Its FLR form factor allows direct compatibility with server FLR slots for streamlined installation and optimal airflow inside rack servers. The design emphasizes stable throughput under sustained loads and predictable performance for storage and compute clusters.

Suitable for

• Virtualization hosts running multiple VMs requiring high network throughput
• Storage networks and iSCSI or NFS traffic aggregation
• High-performance computing nodes and database servers
• Server uplinks in top-of-rack or leaf-spine data center topologies
• Redundant networking setups requiring link aggregation or failover

Key specifications

• Interface: Two SFP+ ports supporting 10 Gigabit Ethernet
• Form factor: FLR-compatible adapter for supported HP Enterprise servers
• Throughput: 10 Gbps per port (full duplex)
• Connectivity media: SFP+ modules (optical transceivers) or Direct Attach Copper (DAC) cables
• Offload features: Hardware offloads for TCP/UDP checksum and segmentation, virtualization offloads (VXLAN/Geneve depending on firmware)
• Latency: Designed for low-latency operation under sustained load
• Power and thermal: Low-profile FLR design to match server cooling and power envelopes

How to use

Install the adapter into a compatible FLR slot on a supported HP Enterprise server following server-specific service manual instructions and anti-static precautions. Insert compatible SFP+ modules or DAC cables into the two SFP+ ports to connect to switches or other 10Gb endpoints. After physical installation, verify firmware and driver compatibility with the server operating system and update drivers or firmware if required. Configure link aggregation, VLANs, MTU size, and offload settings in the operating system or hypervisor network management interface to match your network design.

Recommendations

Use certified SFP+ transceivers or DAC cables and keep firmware and drivers up to date to ensure optimal interoperability and performance. For virtualization or storage environments, enable supported offloads and verify MTU/Jumbo Frame settings end-to-end. When deploying in redundant or aggregated link scenarios, test failover behavior and link speed negotiation with connected switches to confirm consistent throughput and low latency.
