Accortec FlexFabric 10Gb 2-Port 534FLR-SFP+ Adapter

The Accortec FlexFabric 10Gb 2-Port 534FLR-SFP+ Adapter is a pinnacle of modern server-side networking, engineered to deliver scalable, high‑performance connectivity for data centers, enterprise networks, and edge deployments. With two 10Gb SFP+ ports, this FlexFabric adapter provides the bandwidth needed for demanding workloads such as database acceleration, virtualization, storage networks, and real-time analytics. It is designed to fit into standard server PCIe slots, with flexibility to support both full-height and low-profile chassis, ensuring seamless integration into a wide range of server platforms. Built for reliability and efficiency, the 534FLR-SFP+ combines a compact form factor with enterprise-grade features, empowering organizations to consolidate their fabrics, simplify administration, and accelerate application performance across virtualized and physical environments. Whether you’re expanding capacity in a growing data center or upgrading a legacy server to 10Gb speeds, this adapter enables a future-ready network that can scale with your workloads.

• High-performance dual 10Gb Ethernet: The 534FLR-SFP+ delivers up to 20 Gbps of aggregate bandwidth across its two SFP+ ports, enabling parallel data paths that reduce bottlenecks and improve throughput for database queries, virtual machine traffic, storage replication, and high-speed backups. Its design prioritizes low latency and deterministic performance, so latency-sensitive applications experience smoother operation even under heavy load. This makes it an ideal upgrade for dense virtualized environments, hyper-converged infrastructures, and enterprise data centers demanding consistent, high-speed network access.
• Flexible fiber and direct-attach connectivity: Each port uses SFP+ connectors, supporting a wide range of transceivers and cables. You can deploy short-reach DAC (direct-attached copper) cables for inside-rack connections, or install the appropriate optical transceivers (SR, LR, or other compatible modules) to reach switches and storage devices across data center floors. This flexibility simplifies deployment across existing infrastructure and enables cost-effective scaling as your network evolves.
• Designed for virtualization and multi-tenant workloads: The FlexFabric architecture integrates with modern virtualization ecosystems, delivering robust support for virtualization features that modern cloud and data-center workloads rely on. Expect streamlined VM-to-NIC performance, improved CPU efficiency through hardware offloads, and compatibility with common hypervisors and orchestration tools. The adapter’s capability to isolate traffic and apply quality-of-service policies helps ensure predictable performance for multiple tenants and mission-critical applications running on the same server hardware.
• Easy deployment and broad compatibility: The Accortec 534FLR-SFP+ is built to work with leading server platforms and operating systems. It ships with both full-height and low-profile brackets, enabling quick installation in 1U through 4U racks. Robust driver support across Windows Server, Linux distributions, and major virtualization platforms ensures straightforward installation and ongoing maintenance. The adapter integrates with standard network management workflows, letting you monitor link status, throughput, and health alongside other NICs in your environment.
• Reliability, manageability, and efficiency for data centers: Engineered for enterprise reliability, this adapter emphasizes durability, steady operation, and energy efficiency. It employs proven components and firmware designed for long life in dense data-center environments, with features that help manage heat, reduce power draw, and simplify troubleshooting. Administrators benefit from consistent performance, easier cable management via clean port layouts, and compatibility with networking tools that monitor link quality, error rates, and congestion levels.

how to install Accortec FlexFabric 10Gb 2-Port 534FLR-SFP+ Adapter

• Power down the server, unplug power connections, and remove the chassis cover following your hardware’s maintenance procedures.
• Locate an available PCIe slot that matches your server’s form factor; remove the slot cover on the rear I/O panel if necessary.
• Insert the Accortec 534FLR-SFP+ into the PCIe slot, ensuring the connector seats firmly and aligns with the bracket. Secure the card with the appropriate screw to the chassis.
• Install the required SFP+ modules or DAC cables on the two ports. Ensure that the modules or cables are compatible with your network equipment and terminate at the correct distance.
• Power up the server and boot into your operating system. Install or update the NIC drivers from the driver package provided by Accortec or your OS vendor, then reboot if prompted.
• Configure network settings using your preferred management tools. Create and assign VLANs, enable any required offloads or virtualization features, and set QoS policies as needed for your workload mix.
• Verify link status and throughput with diagnostic tools or simple network tests. Check event logs for any hardware or driver messages, and ensure both ports come online with stable connections.

Frequently asked questions

• What is the Accortec FlexFabric 10Gb 2-Port 534FLR-SFP+ Adapter? It is a dual-port 10Gb SFP+ network adapter designed for servers, delivering fast, scalable network connectivity and flexible fiber or DAC options for data centers and enterprise networks.
• What cables or modules do I need? Use SFP+ transceivers appropriate for your distance and environment (SR/LR/ER options are common) or direct-attach copper (DAC) cables for short-range connections within the rack. Ensure compatibility with your switch fabric.
• Which operating systems are supported? Drivers are available for major Linux distributions and Windows Server, with compatibility across common virtualization platforms such as VMware, Hyper-V, and KVM when using standard NIC drivers and features.
• Can I use both ports simultaneously? Yes. The two 10Gb SFP+ ports operate independently, allowing dual-network paths, link aggregation, or separate networks for different workloads depending on your configuration.
• Does it include virtualization offloads? The adapter is designed to work with virtualization features and offloads that improve CPU efficiency and VM performance, subject to driver support and OS capabilities.
• Is this adapter compatible with my server chassis? It is intended for standard PCIe-enabled servers and supports common chassis sizes through its dual-bracket design, but you should verify available PCIe slots and clearance in your specific server model.
