Dual-port 10GbE/1GbE  OCP mezzanine card with low cost, low power, enhancing features and performance


Flexible I/O Virtualization

Wiwynn OCP Mezzanine supports SR-IOV which allows single physical adapter to be visualized as multiple virtual network interface cards (vNICs). It offers greater flexibility, cost minimization, increased density and minimizing cables by using fewer cables, cards and switch ports.


Power Management Technologies

Wiwynn OCP Mezzanine provides excellent low cost and power solutions using IEEE802.3az Energy Efficient Ethernet (EEE). In addition, Wiwynn NM10GR features Intel® DMA Coalescing (DMAC). This enables NIC components to remain in lower power states longer, which can dramatically reduce energy consumption.
