Marvell® Converged Network Adapters 41000 Series Adapters
●The Marvell FastLinQ 41000 Series Adapters include 10 and 25Gb Converged Network Adapters and Intelligent Ethernet Adapters that are designed to perform accelerated data networking for server systems. The 41000 Series Adapter includes a 10/25Gb Ethernet MAC with full-duplex cap
●Using the operating system's teaming feature, you can split your network into virtual LANs (vLANs), as well as group multiple network adapters together into teams to provide network load balancing and fault tolerance. For more information about teaming, see your operating system documen
■Features:
The 41000 Series Adapters provide the following features. Some features may not be available on all adapte:
●NIC partitioning (NPar)/NPar extended partitioning (NParEP)
●Single-chip solution:
◆10/25Gb MAC
◆SerDes interface for direct attach copper (DAC) transceiver connection
◆PCI Express® (PCIe®) 3.0 x8Zero copy capable hardware
●Performance features:
◆TCP, IP, UDP checksum offloads
◆TCP segmentation offload (TSO)
◆Large segment offload (LSO)
◆Generic segment offload (GSO)
◆Large receive offload (LRO)
◆Receive segment coalescing (RSC)
◆Microsoft® dynamic virtual machine queue (VMQ), and Linux Multiqueue
●Adaptive interrupts:
◆Transmit/receive side scaling (TSS/RSS)
◆Stateless offloads for Network Virtualization using Generic Routing Encapsulation (NVGRE) and virtual LAN (VXLAN) L2/L3 GRE tunneled traffic
●Manageability:
◆System management bus (SMB) controller
◆Advanced Configuration and Power Interface (ACPI) 1.1a compliant (multiple power modes)
◆Network controller-sideband interface (NC-SI) support
●Advanced network features:
◆Jumbo frames (up to 9,600 bytes). The OS and the link partner must support jumbo frames.
◆Virtual LANs (VLANs)
◆Flow control (IEEE Std 802.3x)
●Logical link control (IEEE Std 802.2)
●High-speed on-chip reduced instruction set computer (RISC) processor
●Integrated 96KB frame buffer memory (not applicable to all models)
●1,024 classification filters (not applicable to all models)
●Support for multicast addresses through 128-bit hashing hardware function
●Support for VMDirectPath I/O over PCI physical functions
FastLinQ 41000 Series Adapters support VMDirectPath I/O in Linux and ESX environments. VMDirectPath I/O is not supported in Windows environments.
FastLinQ 41000 Series Adapters can be assigned to virtual machines for PCI pass-through operation. However, due to function level dependencies, all PCIe functions associated with an adapter (in default, NPar, or NParEP modes) must be assigned to the same virtual machine. Sharing PCIe physical functions across the hypervisor and any virtual machines;or sharing them across more than one virtual machine, is not supported.
●Serial flash NVRAM memory
●PCI Power Management Interface (v1.1)
●64-bit base address register (BAR) support
●EM64T processor support
●SR-IOV Virtual Functions (VF)
●iSCSI (software (SW) and hardware (HW)) and FCoE boot support
