When network congestion causes application timeouts in AI training clusters, every microsecond
of latency matters. The LREC9812BF-2SFP+ addresses this by delivering reliable, low-latency
connectivity for critical server applications.
Based on the Intel X710 controller, this adapter features dual SFP+ ports supporting 1/10Gbps
data rates. With PCIe v3.0 x8 interface compatibility, it ensures efficient data offloading and
reduced CPU overhead through LSO and GSO support, enabling higher throughput for
virtualized environments.
Ideal for data centers and high-end servers requiring network virtualization, this card supports
SR-IOV, VMDq, and DPDK. Its robust design includes half-height and full-height brackets,
making it versatile for various chassis configurations while maintaining optimal thermal performance.
