FastLinQ 45000 Series Ethernet Adapters

The Marvell® FastLinQ® 45000 Series Ethernet Adapters are advanced high-performance adapters ideally suited for enterprise-class data centers, public and private clouds, managed service providers (MSPs) and telco deployments. The FastLinQ 45000 Series includes adapters that support 10/25/40/50/100Gb Ethernet (10/25/40/50/100GbE) and provide key features like Universal RDMA, server virtualization with NIC partitioning (NPAR) and single root IO virtualization (SR-IOV), networking tunneling with stateless offload for Virtual Extensible LAN (VXLAN), Network Virtualization using Generic Routing Encapsulation (NVGRE), Generic Routing Encapsulation (GRE) and Generic Network Virtualization Encapsulation (GENEVE).

Key Features

  • Scalable networks with 2.5X bandwidth for 25GbE when compared to 10GbE and more than 2X port density when compared to 40GbE
  • Optimum server performance with PCI Express® (PCIe®) Gen3 x8 (25GbE) and x16 (40GbE and 100GbE)
  • Low latency and high throughput with multi-protocol RDMA with support for RDMA over Converged Ethernet (RoCE), RoCE v2 and Internet wide area RDMA protocol (iWARP)
  • Adaptive link controls for seamless zero-touch interoperability with industry wide 10/25/100GbE switches and cables using FastLinQ SmartAN™ technology
  • Enhanced CPU efficiency for network tunneling with stateless offloads for VXLAN, NVGRE, GRE, and GENEVE
  • Advanced server virtualization features such as NPAR and SR-IOV
  • High-performance network storage with iSCSI Extensions for RDMA (iSER), Non-Volatile Memory Express over Fabric (NVMe-oF), Network File System over RDMA (NFSoRDMA), Server Message Block over RDMA (SMB Direct), Storage Spaces Direct (S2D), and VMware para-virtualized RDMA (pvRDMA)
  • Simplified deployment, troubleshooting and lifecycle management using the QConvergeConsole® (QCC) GUI, QCC PowerKit, QLogic® Control Suite (QCS) CLI, vCenter GUI/ESXCLI Plug-ins, and OpenStack integration
  • Enhanced management interface with Management Component Transport Protocol (MCTP) over PCIe support
  • Network boot support for PreBoot Execution Environment (PXE) 2.0, iSCSI remote boot and UEFI boot
