The QXG-25G2SF-CX6 features an NVIDIA Mellanox® ConnectX®-6 Lx SmartNIC controller, supports PCIe Gen4 (backwards compatible with Gen3/ Gen2) and provides up to 25 Gbps transfer speeds (supports 10/25Gbps). By using Port Trunking to combine multiple ports, up to 50GbE can be achieved for accelerating file sharing and intensive data transfer. With SR-IOV support, the QXG-25G2SF-CX6 greatly boosts network efficiency and is ideal for I/O-intensive and latency-sensitive virtualization applications and data centers.
