Dual-port 10GbE server adapter
The LR-LINK LREC9812BF-2SFP+ is a PCI Express 3.0 x8 network card with two SFP+ ports. It delivers 10000 Mbps per port and complies with IEEE 802.3 standards. The card targets administrators deploying high-throughput links in Windows Server, Linux, FreeBSD or VMware ESXi environments.
Intel X710-BM2 controller offloads
The onboard Intel X710-BM2 handles Geneve, VXLAN and NVGRE encapsulation in hardware. Intel Ethernet Flow Director steers application traffic to specific queues, while DPDK optimisation accelerates packet processing for NFV workloads. These offloads reduce host CPU utilisation when running virtualised network functions.
Operates from 0 °C to 55 °C at up to 90 % humidity
The adapter sustains line-rate 10 Gb/s traffic on both ports within the stated thermal envelope. It fits PCIe 3.0 x8 slots and supports jumbo frames for large MTU deployments. Environments requiring more than two 10 GbE ports or a PCIe 2.0 x4 electrical interface will need a different model.

Fragen zu diesem Artikel
Will the SFP+ transceivers in the LREC9812BF-2SFP+ need periodic replacement?
The card uses standard SFP+ modules; replace a transceiver only if a link fails or you change cable type.
What limits sustained throughput on the PCIe 3.0 x8 interface?
The x8 lane width caps theoretical bandwidth at the PCIe 3.0 x8 maximum.
How much heat does the Intel X710-BM2 controller produce under continuous 10 GbE load?
Rated for 0 °C to 55 °C operation; the low-power design keeps thermals within that range without active cooling.
