Intel E10G41BFSR

Overview

The Intel E10G41BFSR is a single-port 10 Gigabit Ethernet converged network adapter designed for servers and workstations that require reliable high-speed connectivity. It uses a PCIe 2.0 x8 interface to deliver full 10 Gbps bandwidth over short-range multimode fiber, reducing latency and offloading network processing from the CPU. This adapter is ideal for data centers, virtualization environments, and storage networks where performance and efficiency are critical.

Key features

• PCIe 2.0 x8 interface provides sufficient bandwidth to support a full 10 Gbps line rate without bottlenecks
• Single 10GBase-SR port enables fast, short-range fiber connections suitable for high-speed data transfer within racks or between nearby equipment
• Intel Ethernet Flow Director and Receive Side Coalescing improve network traffic management, allowing multi-core CPUs to focus more on applications rather than handling interrupts
• SR-IOV and VMDq technologies allow direct bandwidth assignment to individual virtual machines, reducing network contention and simplifying quality-of-service management
• Supports key storage protocols including iSCSI, NFS, and Fibre Channel over Ethernet, enabling traffic consolidation and reducing cabling complexity
• Compatible with major operating systems such as Windows Server, popular Linux distributions, and VMware ESXi, ensuring broad deployment flexibility
• Includes both low-profile and full-height brackets to fit a variety of server chassis and rack configurations
• Status LEDs provide clear, immediate feedback on link speed and network activity for easy monitoring

Connectivity and compatibility

This adapter connects via a PCIe 2.0 x8 slot and uses a 10GBase-SR fiber optic port for network links. It integrates seamlessly with existing data center infrastructure, supporting common storage and virtualization protocols. The broad OS compatibility ensures it can be deployed in diverse environments without driver issues, making it a versatile choice for upgrading network performance.

Performance and reliability

Designed to reduce CPU overhead, the adapter’s advanced traffic management features help maintain smooth data flow even under heavy loads. Its support for SR-IOV and VMDq enhances virtualization performance by allocating network resources efficiently. The robust build and included bracket options ensure reliable operation in both standard and compact server setups.

Ideal uses and environments

This network adapter fits well in data centers, virtualization farms, and high-performance computing clusters where fast, low-latency connections are essential. It is particularly suited for administrators looking to consolidate storage and network traffic onto fewer physical links while maintaining high throughput. Media servers and file servers handling large data assets will also benefit from its speed and protocol support.

Orders are processed within 2 business days, which includes verification, packing, and dispatch. Shipping costs are calculated at checkout based on destination, total weight, and selected speed. Free shipping applies to carts over $100 (excluding heavyweight items). All available options and final pricing are clearly shown before payment so you can choose the service that best fits your needs.

Deliveries are handled by major carriers such as USPS, UPS, and FedEx. Estimated delivery times are displayed at checkout and may vary depending on service level and location. Please note that these are estimates and can be affected by weather, holidays, or carrier volume. Once your order ships, you’ll receive a tracking number for real-time updates from pickup to final delivery.

Providing an accurate shipping address helps prevent delays, and changes may be limited once the order has been dispatched. P.O. boxes are supported only when permitted by the selected carrier. Packaging and handoff are optimized to protect items during transit, though oversized or high-weight products may require special handling. All shipping methods and any related constraints are clearly shown during checkout.

Returns are accepted within 30 days of delivery. Items must be unused, in the same condition received, with tags, manuals, accessories, and original, unaltered packaging. Any item kept will be deducted from the refund. Start a return by sending us an email. Items sent back without approval may be refused or returned to the sender.

Some items are not returnable: opened TVs/combos/monitors 37″+, opened computers or software, electronic downloads, opened consumables (film, paper, bulbs, media, ink), custom or modified computers, special-order or “nonreturnable” items, submerged underwater gear, and opened educational media.

After inspection, refunds are issued to the original payment method; allow 5–7 business days for the credit to post. Shipping, handling, customs duties, and import taxes are nonrefundable. If an item is used, incomplete, or not in original condition, a 30% restocking fee may apply. Direct exchanges are not offered; purchase the replacement and return the original for a refund.

We act solely as a reseller. Any product warranty is provided and administered by the manufacturer, not by our store. That means eligibility, coverage, and outcomes are determined by the manufacturer’s policy for each brand and model. Before purchasing, we recommend reviewing the warranty terms on the manufacturer’s website or in the product documentation to confirm what is covered and for how long.

If you need warranty service, please file the claim directly with the manufacturer. They may require proof of purchase, the product serial number, original packaging, photos, or basic troubleshooting. Some brands ask you to register the product or obtain a case number before shipping it for repair or replacement. We don’t submit or approve claims, but we can point you to the correct support links and contact details.

Keep your invoice and packaging in a safe place, and report any functional issues to the manufacturer as soon as they appear. If you’re unsure whether a problem is covered, the manufacturer’s support team can confirm next steps and timelines. While we cannot intervene in decisions or outcomes, we’re happy to provide purchase documentation or guidance so you can move through the warranty process smoothly.
