Fat tree
There are several common topologies for an InfiniBand fabric. The following lists some of those topologies: Fat tree: A multi-root tree. This is the most popular topology.

How is InfiniBand different from Ethernet?

Higher performance, higher radix and low-latency solutions: Today, Ethernet switches offer connectivity of up to 400 Gbps. In contrast, InfiniBand HDR only offers connectivity of up to 200 Gbps and Fibre channel offers connectivity of up to 32 Gbps.

What layer is InfiniBand?

transport layer
InfiniBand architecture offers a significant improvement for the transport layer over other technologies such as Ethernet: all functions are implemented in the hardware.

What is InfiniBand architecture?

InfiniBand architecture is a new I/O specification that will start to ship in a wide variety of server and interconnect products during 2001. InfiniBand architecture is a well-described technology with a final speci- fication that was prepared by the InfiniBand Trade Association (IBTA) in the fall of 2000.

Does InfiniBand use TCP?

InfiniBand effectively addresses all of the stated limitations of TCP and can provide seamless connectivity to applications designed to work with TCP. Many counter that the industry will develop TOEs (TCP Offload Engines) that will overcome these limitations and lower both latency and CPU utilization.

Where is InfiniBand used?

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.

Does InfiniBand use IP?

Internet Protocol (IP) packets can be sent via an InfiniBand interface by encapsulating the IP packets in an InfiniBand packet via a network interface. This is known as IP over IB (IPoIB).

What is InfiniBand and what are its applications?

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. It is designed to be scalable and uses a switched fabric network topology.

What are the benefits of InfiniBand?

Fabric consolidation and low energy usage: InfiniBand can consolidate networking, clustering, and storage data over a single fabric which significantly lowers the overall power, real estate and management overhead required for servers and storage.

What is InfiniBand and what is it used for?

InfiniBand is also used as either a direct or switched interconnect between servers and storage systems, as well as an interconnect between storage systems. As of 2014, it was the most commonly used interconnect in supercomputers.

What is Ethernet over InfiniBand (EoIB)?

Ethernet over InfiniBand, abbreviated to EoIB, is an Ethernet implementation over the InfiniBand protocol and connector technology. EoIB enables multiple Ethernet bandwidths varying on the InfiniBand (IB) version.

When did the InfiniBand architecture specification come out?

At 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. 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,…

Who makes InfiniBand switches?

Mellanox (now Nvidia Networking) manufactures InfiniBand host bus adapters and network switches, and, in February 2016, it was reported that Oracle Corporation had engineered its own InfiniBand switch units and server adapter chips for use in its own product lines and by third parties.
