When virtual machine density increases I/O bottlenecks in data centers, efficient network processing
becomes critical for maintaining application performance. The LREC9802BF-2SFP+ network adapter
addresses this challenge with hardware-accelerated virtualization support.
Built on the Intel 82599 controller, this dual-port 10G SFP+ card delivers 20Gbps aggregate bandwidth
via PCIe 2.0 x8 interface, enabling high-throughput connectivity without slot congestion. Features like
VMDq and SR-IOV offload sorting tasks from the host CPU, significantly improving VM scalability and
reducing latency in multi-tenant environments.
Ideal for unified LAN/SAN traffic and cloud infrastructure, this adapter supports FCoE and iSCSI to
consolidate network and storage flows. With broad OS compatibility and low 8.9W power consumption,
it offers reliable, energy-efficient 10G deployment for evolving virtualized data centers.
