Applications
InfiniBand has been adopted in enterprise datacenters, for example Oracle Exadata Database Machine, Oracle Exalogic Elastic Cloud and Oracle SPARC SuperCluster, financial sectors, cloud computing (an InfiniBand based system won the best of VMWorld for Cloud Computing) and more. InfiniBand has been mostly used for high performance clustering computer cluster applications. A number of the TOP500 supercomputers have used InfiniBand including the former reigning fastest supercomputer, the IBM Roadrunner.
SGI, LSI, DDN, Oracle, Rorke Data among others, have also released storage utilizing InfiniBand "target adapters". These products essentially compete with architectures such as Fibre Channel, SCSI, and other more traditional connectivity-methods. Such target adapter-based discs can become a part of the fabric of a given network, in a fashion similar to DEC VMS clustering. The advantage to this configuration is lower latency and higher availability to nodes on the network (because of the fabric nature of the network). In 2009, the Oak-Ridge National Lab Spider storage system used this type of InfiniBand attached storage to deliver over 240 gigabytes per second of bandwidth.
