Intel PCIe 2.0 x8 - 10GBase-SR x 2 Ethernet Converged Network Adapter

The Intel E10G42BFSR is a dual-port network adapter that delivers 10-gigabit Ethernet over short-range fiber through a PCIe 2.0 x8 slot. It is built for servers that need dependable, low-latency throughput and a straightforward path to higher bandwidth without a complete infrastructure overhaul.

Inside a virtualized environment, the card earns its keep. Virtual Machine Device Queues and Single Root I/O Virtualization let each virtual machine move data with fewer CPU interrupts, so consolidation projects can run more guests while keeping response times predictable. This makes the adapter a natural fit for private clouds, VMware clusters, and other virtualization-heavy workloads.

The card also supports iSCSI, NFS, and Fibre Channel over Ethernet. Storage traffic, backup jobs, and ordinary IP packets can all share the same physical link, which simplifies cabling and cuts switch port counts in a rack. Data center operators who want to converge storage and LAN traffic on one fabric will find the feature set ready out of the box.

A low-profile bracket ships in the box, so the adapter slides into full-height or slim servers with equal ease. Once installed, it works quietly in the background, covered by a lifetime limited warranty that protects the investment over multiple hardware refresh cycles.
