Mellanox OpenFabrics Enterprise Distribution for Linux (MLNX_OFED)

Overview

High-performance server and storage connectivity software for field-proven RDMA and Transport Offload hardware solutions.

Use of clustered commodity servers, in lieu of traditional supercomputers and mainframes, offers tremendous price/performance benefits and unparalleled flexibility in deployment and long-term maintenance. To enable distributed computing transparently, high-performance computing (HPC) applications require the highest bandwidth and lowest possible latency. In enterprise data center (EDC) applications, these requirements are compounded with the need to support a large interoperable ecosystem of networking, virtualization, storage, and other applications and interfaces.

Mellanox OFED is a single Virtual Protocol Interconnect (VPI) software stack based on the Open- Fabrics (OFED) Linux stack, and operates across all Mellanox network adapter solutions supporting 10, 20 and 40Gb/s InfiniBand (IB); 10Gb/s Ethernet (10GigE); Fibre Channel over Ethernet (FCoE); and 2.5 or 5.0 GT/s PCI Express 2.0 uplinks to servers.

  • Single software VPI stack supporting InfiniBand (10/20/40 Gb/s), Ethernet (10 Gb/s), FCoE, PCI-X, and PCI Express modes (Gen1 & Gen2)
  • VPI software stack allows Mellanox ConnectX devices to run both InfiniBand and 10GigE traffic simultaneously on two ports
  • Support for HPC applications for scientific research, oil and gas exploration, car crash tests, bench marking etc. E.g., Fluent, LS-DYNA
  • Support for EDC applications such as Oracle 11g/10g RAC, IBM DB2, SAP, and financial applications
  • Support for high-performance block storage applications utilizing RDMA benefits
  • Support for end-to-end QoS using centralized QoS manager for delivering no compromise unified I/O services
  • Support for cluster management tools
