2 RJ45,Ethernet Adapter

LREC9722PT Intel 82575 PCI-Express x4 10/100/1000Mbps 2 RJ45 Port Server Ethernet Adapter Support VDMq(Intel 82575 Based)


Descriptions

LREC9722PT is R&D PCI-Express x4 1000Mbps Dual port ethernet network card by Shenzhen Lianrui Electronics CO.,LTD(LR-LINK).The LREC9722PT ethernet adapter card design for servers and high-end equipment, and the performance is optimized, make the system I/O is no longer a high-end bottleneck. LREC9722PT can realize fault tolerance by bundling group, communication from fault port will be routed to the other members.
LREC9722PT is two Port server ethernet adapter,it can multiport fiber connecting to improve internet fuctions,at the same time,it will save PCI-Express slot. In the fiber gigabit network,PCI-Express I/O can ensure the fuctions,and save the bus bandwidth.
