Marvell FastLinQ 41000 Series
Industry Leading 25/10GbE Controllers

Overview
FastLinQ® 41000 Series Ethernet Controllers are single, duel, and quad-port Ethernetsolutions designed for high-volume, converged network applications. The
QL41000 Series Controllers support speeds of 25/10/1Gbps and enable single root I/Ovirtualization (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 virtualbridging and other switching technologies for virtual machine (VM)-to-VM switching.

• Single, dual, and quad-port
10GbE applications• Single and dual-port 25GbEapplications• NVMe-oF NVMe™ over Fabrics
with RDMA and TCP• Secure firmware updateprocess with private/public key
encryption technology prevents
hackers from altering adapter

The FastLinQ 41000 Series is a complete solution that enables leading-edge features forthe enterprise and cloud (independent of server form factor), while significantly accelerating network performance. This controller enables stateful and stateless offloads, andincludes advanced features such as network virtualization offload, storage offloads,
secure firmware update with private/public key encryption, and FastLinQ SmartAN™ for
simplified connectivity to switches without user intervention.
The QL41000 Series Controllers include support for 25GbE applications (single port anddual port) and 10GbE applications (single port, dual port, and quad port). CNAs support
iSCSI and FCoE hardware-based offload. FastLinQ 41000 Series Controllers integrate
four IEEE 802.3-compliant MACs and support the network controller-sideband interface(NC-SI). Host-to-baseboard management controller (BMC) communication is also
supported on top of NC-SI to permit high-speed communication between the local hostand the BMC or management controller (MC).

• Low-power, single-chip solution
with adaptive voltage scaling• Universal RDMA—RoCE,
RoCEv2, and iWARP• VXLAN, NVGRE, GRE, and
GENEVE tunneling offloads• T10 Protection Information• SR-IOV and NPAR
