Linux Drivers

Mellanox OpenFabrics Enterprise Distribution for Linux (MLNX_OFED)

Clustering using commodity servers and storage systems is seeing widespread deployments in large and growing markets such as high performance computing, Artificial Intelligence (AI), data warehousing, online transaction processing, financial services and large scale cloud deployments. To enable distributed computing transparently and with maximum efficiency, applications in these markets require the highest I/O bandwidth and lowest possible latency. These requirements are compounded with the need to support a large interoperable ecosystem of networking, virtualization, storage, and other applications and interfaces. The OFED from OpenFabrics Alliance ( has been hardened through collaborative development and testing by major high performance I/O vendors. Mellanox OFED (MLNX_OFED) is a Mellanox tested and packaged version of OFED that supports two interconnect types using the same RDMA (remote DMA) and kernel bypass APIs called OFED verbs – InfiniBand and Ethernet. Up to 200Gb/s InfiniBand and RoCE (based on the RDMA over Converged Ethernet standard) over 10/25/40/50/100GbE are supported with OFED by Mellanox to enable OEMs and System Integrators to meet the needs end users in the said markets.
