Quad-port, dual-port, and single-port 25GbE and 10GbE converged network controllers

FastLinQ 41000 Series Ethernet Controllers

The Marvell® FastLinQ® 41000 Series of Ethernet controllers are an eighth-generation solution designed for high-volume, converged network applications. They support speeds of 25Gbps and 10Gbps and enable single root I/O virtualization (SR-IOV), universal remote direct memory access (RDMA) over converged Ethernet (RoCE), iSCSI, Fibre Channel over Ethernet (FCoE), and data center bridging (DCB). They also support PCI Express (PCIe) Gen 3, along with embedded virtual bridging and other switching technologies for virtual machine (VM)-to-VM switching.
