M.2 to 10GbE SFP+ Fiber Network Card X520-DA1, Intel JL82599EN 10 Gigabit Ethernet Controller, Single Port, M.2 B+M Key, for Server, Industrial PC, and Embedded Systems

Bring enterprise-grade 10 Gigabit networking to compact systems with this M.2 to 10GbE SFP+ Fiber Network Card. Powered by the Intel JL82599EN 10 Gigabit Ethernet controller, this adapter enables high-speed fiber or direct-attach copper (DAC) connectivity for systems equipped with an M.2 B+M Key slotperfect for industrial PCs, embedded servers, network appliances, and compact workstation builds.

The card utilizes a PCIe 2.0 x8 interface (5GT/s) over the M.2 connection, delivering ample bandwidth to support full 10Gbps line-rate throughput. The single SFP+ port is compatible with a variety of optical transceivers (10GBASE-SR, 10GBASE-LR) as well as SFP+ Direct Attach Copper (DAC) cables, providing flexible deployment options for data center, enterprise, and edge applications.

Built on the trusted Intel 82599EN architecture, this adapter delivers advanced features including Receive Side Scaling (RSS) for multi-core processor optimization, checksum and large send offload to reduce CPU overhead, and support for jumbo frames up to 15.5K for improved throughput in large data transfers. Virtualized environments benefit from VM device queues (VMDq) and SR-IOV support, enabling efficient traffic handling across multiple virtual machines.

Management capabilities are extensive, with support for PXE remote boot, Wake-on-LAN (WoL), VLAN filtering, and IPMI pass-through via SMBus or NC-SI, making this card ideal for remote deployment and server management scenarios.

The card is compatible with a wide range of operating systems including Windows, Windows Server, Linux, FreeBSD, and VMware ESXi, ensuring seamless integration into existing infrastructure.
