LREC9902BF 2QSFP PCIE 3 0x8 зарядное устройство с двумя портами 40 GbE адаптер XL710 QDA2 эфирной сети сетевая карта сетевого адаптера

LR-LINK LREC9901BF-QSFP+ is based on Intel XL710BM1 Ethernet controller with two fully integrated Gigabit Ethernet Media Access Control (MAC) and XLPPI Interface.

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.

LR-LINK LREC9901BF-QSFP+ is the ideal solution for implementing multiple network segments, mission-critical high-powered networking applications and environments within high performance servers.
