QSFP+ 40 Gigabit Ethernet PCI Express CNA/NIC

10Gtek's L710-1QS QSFP+ 40 Gigabit Ethernet PCI Express server adapters are designed for Servers and high-end appliances. The performance is optimized so that system I/O is not the bottleneck in high-performance networking applications. In addition to managing MAC and PHY Ethernet layer functions, the controller manages PCI Express packet traffic across its transaction, link, and physical/logical layers. Using hardware acceleration, the controller offloads tasks from the host, such as TCP/UDP/IP checksum calculations and TCP segmentation.
