1/8/2024 0 Comments Top speed ns 200Of the top 500 supercomputers in 2009, Gigabit Ethernet was the internal interconnect technology in 259 installations, compared with 181 using InfiniBand. In November 2005 storage devices finally were released using InfiniBand from vendors such as Engenio. By February, 2005, the support was accepted into the 2.6.11 Linux kernel. The OpenIB Alliance (later renamed OpenFabrics Alliance) was founded in 2004 to develop an open set of software for the Linux kernel. In 2003, the System X supercomputer built at Virginia Tech used InfiniBand in what was estimated to be the third largest computer in the world at the time. īy 2002, Intel announced that instead of shipping IB integrated circuits ("chips"), it would focus on developing PCI Express, and Microsoft discontinued IB development in favor of extending Ethernet. įollowing the burst of the dot-com bubble there was hesitation in the industry to invest in such a far-reaching technology jump. Mellanox had been founded in 1999 to develop NGIO technology, but by 2001 shipped an InfiniBand product line called InfiniBridge at 10 Gbit/second speeds. IBTA also envisaged decomposing server hardware on an IB fabric. Initially the IBTA vision for IB was simultaneously a replacement for PCI in I/O, Ethernet in the machine room, cluster interconnect and Fibre Channel. Version 1.0 of the InfiniBand Architecture Specification was released in 2000. This led to the formation of the InfiniBand Trade Association (IBTA), which included both sets of hardware vendors as well as software vendors such as Microsoft.Īt the time it was thought some of the more powerful computers were approaching the interconnect bottleneck of the PCI bus, in spite of upgrades like PCI-X. NGIO was led by Intel, with a specification released on 1998, and joined by Sun Microsystems and Dell.įuture I/O was backed by Compaq, IBM, and Hewlett-Packard. InfiniBand originated in 1999 from the merger of two competing designs: Future I/O and Next Generation I/O (NGIO). The technology is promoted by the InfiniBand Trade Association. Īs a computer cluster interconnect, IB competes with Ethernet, Fibre Channel, and Intel Omni-Path. ![]() 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. ![]() It is designed to be scalable and uses a switched fabric network topology.īy 2014, it was the most commonly used interconnect in the TOP500 list of supercomputers, until about 2016. ![]() 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 used for data interconnect both among and within computers. InfiniBand ( IB) is a computer networking communications standard used in high-performance computing that features very high throughput and very low latency.
