Version 1.0 of the InfiniBand Architecture Specification was released in 2000. 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. IBTA also envisaged decomposing server hardware on an IB fabric.
3.0 is the "base" or "core" specification. The AdvancedTCA definition alone defines a Fabric agnostic chassis backplane that can be used with any of the Fabrics defined in the following specifications: 3.1 Ethernet (and Fibre Channel) 3.2 InfiniBand; 3.3 StarFabric; 3.4 PCI Express (and PCI Express Advanced Switching) 3.5 RapidIO
All other socket types (such as datagram, raw, packet, etc.) are supported by the Linux IP stack and operate over standard IP interfaces (i.e., IPoIB on InfiniBand fabrics). The IP stack has no dependency on the SDP stack; however, the SDP stack depends on IP drivers for local IP assignments and for IP address resolution for endpoint ...
Applications access control structures using well-defined APIs originally designed for the InfiniBand Protocol (although the APIs can be used for any of the underlying RDMA implementations). Using send and completion queues, applications perform RDMA operations by submitting work queue entries (WQEs) into the submission queue (SQ) and getting ...
The Virtual Interface Architecture (VIA) is an abstract model of a user-level zero-copy network, and is the basis for InfiniBand, iWARP and RoCE.Created by Microsoft, Intel, and Compaq, the original VIA sought to standardize the interface for high-performance network technologies known as System Area Networks (SANs; not to be confused with Storage Area Networks).
This is a list of interface bit rates, is a measure of information transfer rates, or digital bandwidth capacity, at which digital interfaces in a computer or network can communicate over various kinds of buses and channels.
There are several modules available offering Infiniband connectivity on the M1000e chassis. Infiniband offers high bandwidth/low-latency intra-computer connectivity such as required in Academic HPC clusters, large enterprise datacenters and cloud applications. [51] There is the SFS M7000e InfiniBand switch from Cisco.
Others expected that InfiniBand will keep offering a higher bandwidth and lower latency than what is possible over Ethernet. [17] The technical differences between the RoCE and InfiniBand protocols are: Link Level Flow Control: InfiniBand uses a credit-based algorithm to guarantee lossless HCA-to-HCA communication. RoCE runs on top of Ethernet.
