Network adapter Dell QLogic FastLinQ 41262 Dual 10GbE PCIe, model 540-BCJF

Dell QLogic FastLinQ 41262 Dual 10GbE PCIe network adapter (model 540-BCJF) delivers two 10 Gigabit Ethernet ports over a PCIe interface, designed for integration into servers and workstations. The card provides high-throughput connectivity with low latency, supporting demanding data-center workloads, virtualization hosts and storage networks. It installs in a standard PCIe slot and works with common server platforms to expand network capacity and improve application performance.

Advantages

The dual 10GbE design offers redundancy and aggregated bandwidth for throughput-intensive applications. Hardware offloads and optimized drivers reduce CPU load and latency, improving overall system efficiency. The adapter supports standard Ethernet protocols and is compatible with common operating systems used in enterprise environments, simplifying deployment and management. Compact PCIe form factor allows installation in a variety of server and workstation chassis.

Suitable for

• Virtualization hosts running multiple VMs or containers
• Storage networks and backup systems requiring high throughput
• Database and application servers with heavy network I/O
• Data-center aggregation and top-of-rack connectivity
• High-performance workstations needing 10GbE connectivity

Key specifications

• Interface: PCI Express x8/x16 compatible card
• Network ports: 2 × 10 Gigabit Ethernet
• Throughput: Up to 20 Gbps aggregate (full duplex)
• Latency: Low-latency hardware design with offload capabilities
• Offloads: TCP/UDP/IP checksum, segmentation offload and virtualization offloads
• Form factor: Low-profile bracket option compatible with server and workstation chassis
• Management: Driver support for major enterprise operating systems and management utilities

How to use

Power down the host system and insert the adapter into an available PCIe slot that meets the card’s lane requirements. Secure the bracket, reassemble the chassis and power on the system. Install or update the vendor-recommended drivers and management tools for the target operating system to enable full functionality, including offloads and advanced features. Configure network settings in the operating system or hypervisor, assign IP addresses or VLANs as needed, and verify link status through system logs or management utilities.

Usage recommendations

For optimal performance, use the adapter with compatible switches and cabling rated for 10GbE, enable hardware offloads in drivers, and keep firmware and drivers up to date. When deploying in virtualized environments, allocate sufficient PCIe lanes and consider using SR-IOV or other virtualization offload features to reduce host CPU utilization.
