OFED
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 industries. The OpenFabrics Alliance aims to develop open-source software that supports the three major RDMA fabric technologies: InfiniBand, RDMA over Converged Ethernet (RoCE) and iWARP. The software includes two packages, one that runs on Linux and FreeBSD and one that runs on Microsoft Windows. The alliance worked with two large Linux distributors—SUSE and Red Hat—as well as Microsoft on compatibility with their operating systems. History Founded in June 2004 as the OpenIB Alliance, the organization originally developed an InfiniBand software stack for Linux. Initial funding for the Alliance was provided by the United States Department of Energy. The alliance released the first vers ...

SCSI RDMA Protocol
In computing the SCSI RDMA Protocol (SRP) is a protocol that allows one computer to access SCSI devices attached to another computer via remote direct memory access (RDMA).ANSI T10 SRPr16a, www.t10.org ANSI T10 SRPr16a, web.archive.org /ref> The SRP protocol is also known as the SCSI Remote Protocol. The use of RDMA makes higher throughput and lower latency possible than what is generally available through e.g. the TCP/IP communication protocol. Though the SRP protocol has been designed to use RDMA networks efficiently, it is also possible to implement the SRP protocol over networks that do not support RDMA.

InfiniBand
InfiniBand (IB) is a computer networking communications standard used in high-performance computing that features very high throughput and very low latency. It is used for data interconnect both among and within computers. InfiniBand is also used as either a direct or switched interconnect between servers and storage systems, as well as an interconnect between storage systems. It is designed to be scalable and uses a switched fabric network topology. By 2014, it was the most commonly used interconnect in the TOP500 list of supercomputers, until about 2016. Mellanox (acquired by Nvidia) manufactures InfiniBand host bus adapters and network switches, which are used by large computer system and database vendors in their product lines. As a computer cluster interconnect, IB competes with Ethernet, Fibre Channel, and Intel Omni-Path. The technology is promoted by the InfiniBand Trade Association. History InfiniBand originated in 1999 from the merger of two competing designs: F ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sockets Direct Protocol
The Sockets Direct Protocol (SDP) is a transport-agnostic protocol to support stream sockets over remote direct memory access (RDMA) network fabrics. SDP was originally defined by the Software Working Group (SWG) of the InfiniBand Trade Association. Originally designed for InfiniBand (IB), SDP is currently maintained by the OpenFabrics Alliance. Protocol SDP defines a standard wire protocol over an RDMA fabric to support stream sockets (SOCK_STREAM). 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 manner which is transparent to the application. Solaris 10 and Solaris 11 Express include support for SDP. Several other Unix operating system variants plan to include support for Sockets Dire ...

RDMA Over Converged Ethernet
RDMA over Converged Ethernet (RoCE) or InfiniBand over Ethernet (IBoE) is a network protocol that allows remote direct memory access (RDMA) over an Ethernet network. It does this by encapsulating an InfiniBand (IB) transport packet over Ethernet. There are two RoCE versions, RoCE v1 and RoCE v2. RoCE v1 is an Ethernet link layer protocol and hence allows communication between any two hosts in the same Ethernet broadcast domain. RoCE v2 is an internet layer protocol which means that RoCE v2 packets can be routed. Although the RoCE protocol benefits from the characteristics of a converged Ethernet network, the protocol can also be used on a traditional or non-converged Ethernet network. Background Network-intensive applications like networked storage or cluster computing need a network infrastructure with a high bandwidth and low latency. The advantages of RDMA over other network application programming interfaces such as Berkeley sockets are lower latency, lower CPU load and highe ...

IWARP
iWARP is a computer networking protocol that implements remote direct memory access (RDMA) for efficient data transfer over Internet Protocol networks. Contrary to some accounts, iWARP is not an acronym. Because iWARP is layered on Internet Engineering Task Force (IETF)-standard congestion-aware protocols such as Transmission Control Protocol (TCP) and Stream Control Transmission Protocol (SCTP), it makes few requirements on the network, and can be successfully deployed in a broad range of environments. History In 2007, the IETF published five Request for Comments (RFCs) that define iWARP: # RFC 5040 ''A Remote Direct Memory Access Protocol Specification'' is layered over Direct Data Placement Protocol (DDP). It defines how RDMA Send, Read, and Write operations are encoded using DDP into headers on the network. # RFC 5041 ''Direct Data Placement over Reliable Transports'' is layered over MPA/TCP or SCTP. It defines how received data can be directly placed into an upper layer ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

University Of New Hampshire InterOperability Laboratory
The University of New Hampshire InterOperability Laboratory (UNH-IOL) is an independent test facility that provides interoperability and standards conformance testing for networking, telecommunications, data storage, and consumer technology products. Founded in 1988, it employs approximately 25 full-time staff members and over 100 part-time undergraduate and graduate students, and counts over 150 companies as members. History The UNH-IOL began as a project of the University's Research Computing Center (RCC). In 1988 the RCC was testing Fiber Distributed Data Interface (FDDI) equipment with the intention of deploying it in its network. The RCC found that equipment from two vendors did not work together and contacted the vendors to find a solution. The two vendors cooperated with the RCC to solve the problem which was caused by differences between the draft and final FDDI specification. During this same time period the RCC was testing 10BASE-T Ethernet interfaces for another projec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
