FastLinQ 3400 Series Ethernet Adapters

Marvell® FastLinQ® 3400 Series 10GbE Ethernet Adapters provide exceptional value in delivering industry-leading features and performance to enable the most efficient and agile software-defined data centers (SDDNs). Designed for server and network virtualization, the 3400 Series Adapters provide stateless offload support for VXLAN/NVGRE and SR-IOV to boost server CPU efficiency and maximize application performance.

Key Features

  • Available in 10GBASE-T (RJ45), SR optic, and direct attach copper (DAC)—support LAN (TCP/IP) traffic at 10Gbps Ethernet (GbE) line-rate speeds.
  • PCIe Gen3 x 8
  • Delivers full line-rate 10GbE performance across both ports
  • Enables provisioning of 10GbE ports for greater deployment flexibility through switch-independent NIC partitioning (NPAR)
  • Boosts host CPU efficiency with hardware offloads for NVGRE and VXLAN tunnels
  • Improves reliability and interoperability—leverages our market-proven Ethernet architecture and software
  • Simplified deployment, troubleshooting and lifecycle management using the QConvergeConsole® GUI, QLogic Control Suite (QCC) CLI, vCenter Plug-in, and OpenStack integration
  • 10GBASE-T version provides a low-cost and easy-to-install RJ45 network connectivity solution that is backward compatible with existing 1GbE
  • Energy Efficient Ethernet (EEE) support reduces idle power consumption in RJ45-based networks
  • Network boot support for pre-execution environment (PXE) 2.0
  • PCI-SIG single root input/output virtualization (SR-IOV)
  • Data center bridging (DCB)
  • Low-profile PCIe form factor
