Mellanox network adapter and switches supported remote direct memory access (RDMA) and RDMA over Converged Ethernet. Product names included: The ConnectX product family of multi-protocol ASICs and adapters supports virtual protocol interconnect (VPI), enabling support for both Ethernet and InfiniBand traffic at speeds up to 200 Gbit/s. The ...
RDMA over Converged Ethernet (RoCE) [1] is a network protocol which allows remote direct memory access (RDMA) over an Ethernet network. There are multiple RoCE versions. RoCE v1 is an Ethernet link layer protocol and hence allows communication between any two hosts in the same Ethernet broadcast domain.
It was jointly developed by Microsoft and 3Com Corporation and is mostly used in Microsoft Windows.However, the open-source NDISwrapper and Project Evil driver wrapper projects allow many NDIS-compliant NICs to be used with Linux, FreeBSD and NetBSD.
Both Red Hat Enterprise Linux and Red Hat Enterprise MRG [10] have support for RDMA. Microsoft supports RDMA in Windows Server 2012 via SMB Direct. VMware ESXi also supports RDMA as of 2015. Common RDMA implementations include the Virtual Interface Architecture, RDMA over Converged Ethernet (RoCE), InfiniBand, Omni-Path and iWARP.
The OpenFabrics Alliance is a non-profit organization that promotes remote direct memory access (RDMA) switched fabric technologies for server and storage connectivity. . These high-speed data-transport technologies are used in high-performance computing facilities, in research and various indus
It is released under two licenses GPL2 or BSD license for Linux and FreeBSD, and as Mellanox OFED for Windows (product names: WinOF / WinOF-2; attributed as host controller driver for matching specific ConnectX 3 to 5 devices) [36] under a choice of BSD license for Windows.
SDP uses various RDMA network features for high-performance zero-copy data transfers. SDP is a pure wire-protocol level specification and does not go into any socket API or implementation specifics. The purpose of the Sockets Direct Protocol is to provide an RDMA-accelerated alternative to the TCP protocol on IP. The goal is to do this in a ...
The motivation for iSER is to use RDMA to avoid unnecessary data copying on the target and initiator. The Datamover Architecture (DA) defines an abstract model in which the movement of data between iSCSI end nodes is logically separated from the rest of the iSCSI protocol; iSER is one Datamover protocol.
