Accortec FlexFabric 10Gb 2-Port 554FLR-SFP+ Adapter

The Accortec FlexFabric 10Gb 2-Port 554FLR-SFP+ Adapter is a cutting-edge networking solution engineered for businesses and power users who demand dependable, high-speed connectivity. Built around a PCI Express x8 interface and fortified with FlexibleLOM technology, this dual-port 10Gb SFP+ NIC is designed to deliver exceptional performance in data centers, virtualization hosts, and enterprise servers. Whether you’re deploying a virtualized environment, building a hyper-converged infrastructure, or running latency-sensitive workloads, the 554FLR-SFP+ Adapter provides the speed, flexibility, and reliability you need to keep networks fast, responsive, and scalable.

With two high-performance SFP+ ports, this adapter offers versatile connectivity options for fiber and direct-attach networks, empowering you to optimize your fabric for storage, data transfer, and compute workloads. FlexibleLOM enables easy upgrades and reconfigurations without swapping out the entire card, reducing maintenance windows and downtime while preserving investment in your server hardware. The result is a future-proof NIC that grows with your network needs—from simple server upgrades to complex, multi-host deployments—without sacrificing stability or performance.

• Dual 10Gbps SFP+ ports provide up to 20Gbps of aggregate bandwidth, enabling high-throughput data transfers for virtualization, databases, big data analytics, and large-scale file movements. With intelligent load balancing and link aggregation options, you can optimize traffic distribution across multiple virtual machines and applications while maintaining predictable, low-latency performance.
• FlexibleLOM technology delivers modular, field-upgradable networking capabilities. This design lets you adapt to evolving network requirements—adding new features or upgrading performance without replacing the entire adapter or server—reducing downtime and total cost of ownership.
• PCI Express x8 interface ensures a wide, high-bandwidth pathway between the host server and the NIC, minimizing bottlenecks and delivering consistent data transfer performance in dense virtualization, storage, and high-traffic workloads. This makes it well-suited for virtualized hosts, hyper-converged clusters, and corner-to-edge network services.
• Advanced offloads and virtualization support maximize VM density and performance. Hardware-assisted features streamline traffic handling, improve VMQ/SR-IOV compatibility, and enable efficient network virtualization. The adapter is designed to work seamlessly with major hypervisors, enabling you to optimize network segmentation, isolation, and QoS across clustered environments.
• Enterprise-grade reliability and manageability underpin sustained operation in demanding environments. Robust drivers for Windows and Linux, together with standard NIC management tools and clear firmware update paths, help simplify deployment, monitoring, and ongoing maintenance across data centers and enterprise networks.

Technical Details of Accortec FlexFabric 10Gb 2-Port 554FLR-SFP+ Adapter

• Get this information from the specifications section of the product on the vendor’s site using the UPC or SKU as reference. Detailed data such as form factor, port configuration, data rate per port, supported standards, and compatibility are listed there. For precise figures and official figures, refer to the vendor’s product entry and ensure correct UPC/SKU alignment.

How to install Accortec FlexFabric 10Gb 2-Port 554FLR-SFP+ Adapter

• Power down the server and unplug all cables. Open the chassis and locate an available PCIe slot that matches the card’s form factor (the 554FLR-SFP+ typically fits standard PCIe x8 slots; verify height and clearance for your server model).
• Remove the chassis slot cover if needed, align the adapter with the PCIe slot, and firmly but gently seat the card into the slot. Secure the bracket with the appropriate screw to ensure a stable physical connection.
• Install the appropriate SFP+ transceivers or DAC cables for your network plan. Choose the correct fiber type and wavelength for your switches or storage targets (e.g., SR/LR modules or copper direct-attach cables) and connect the cables to the two SFP+ ports.
• Power on the server, boot the operating system, and install the latest drivers and management utilities from the vendor. Confirm the NIC is detected in the device manager or through your OS network configuration tools, and verify that the adapter shows two active ports.
• Configure networking as required: create NIC teams or bonds for redundancy and load balancing, enable virtualization features such as SR-IOV or VMQ if supported by your hypervisor, and implement QoS or traffic shaping rules to prioritize latency-sensitive workloads. Validate connectivity with a quick throughput and latency test to ensure optimal performance.
