The Intel E10G41BFSR is a single-port 10 Gigabit Ethernet adapter built for servers and workstations that demand dependable high bandwidth. It fits into any system with an available PCIe 2.0 x8 slot and uses short-range fiber to move data at up to 10 Gbps, keeping latency low while freeing up processor resources for the workloads that matter.

Inside a data center, the card brings quick, low-overhead links between servers, storage arrays, and network switches. Engineers running virtualized hosts can rely on built-in SR-IOV and VMDq support to assign bandwidth directly to individual virtual machines, trimming contention and simplifying quality-of-service planning. Intel Ethernet Flow Director and Receive Side Coalescing further streamline packet handling so that multi-core CPUs spend less time on network interrupts and more time on application processing.

The adapter speaks the protocols that modern storage fabrics depend on, including iSCSI, NFS, and Fibre Channel over Ethernet. That flexibility lets administrators consolidate traffic onto a single physical link, reducing cable count and port expenses without compromising performance. Whether you are building a new cluster for high-performance computing, expanding a virtualization farm, or upgrading a file server that feeds large media assets, this card integrates smoothly.

Deployment is straightforward. Drivers ship with major versions of Windows Server, every mainstream Linux distribution, and VMware ESXi, so installation rarely extends beyond seating the card and applying fiber patch cables. A low-profile bracket is included, allowing the adapter to fit in both full-height racks and compact chassis.

Highlights:
  • PCIe 2.0 x8 interface delivers ample bandwidth for a full 10 Gbps line rate
  • Single 10GBase-SR port supports short-range multimode fiber connections
  • Intel Ethernet Flow Director and Receive Side Coalescing optimize traffic across multi-core CPUs
  • SR-IOV and VMDq enable direct bandwidth allocation to virtual machines
  • Compatible with iSCSI, NFS, and Fibre Channel over Ethernet storage networks
  • Works with Windows Server, leading Linux distributions, and VMware ESXi
  • Low-profile and full-height brackets included for flexible server installation
  • Status LEDs provide at-a-glance confirmation of link speed and activity
