57840-4SFP+is a PCI Express x8 quad port SFP+10G Ethernet network adapter developed based on the Broadcom BCM57840 main control solution, and is compatible with x16 channels. This Ethernet network adapter meets the needs of next-generation data centers by providing unparalleled features for server and network virtualization. 57840-4SFP+has a flexible 4-port 10GbE link rate on a PCI Express v3.0 x8 slot, making it easy to use in environments with multiple network deployment requirements. This adapter is mainly designed for servers and high-end devices, so that system I/O is no longer a bottleneck for high-end network applications. At the same time, this adapter can bundle and aggregate multiple ports into groups to achieve fault tolerance and redundancy to ensure network performance or expand network bandwidth. It can detect and route communication from faulty ports to other members in the same group in real time to continue running and achieve uninterrupted high-performance communication. At the same time, the adapter uninstalls LSO from the host software, GSO， Thereby reducing CPU overhead. Release CPU resources to handle other applications. This adapter is an ideal solution for deploying multiple networks and critical network applications and environments on high-performance servers.
