Sun Fire Link is an optical interconnect technology that speeds cluster communication among up to eight high-end Sun systems — from the Sun Fire 6800 to the Sun Fire 15K server — powering up to 800 processors.
The interconnect offers high bandwidth and low latency, allowing users to build super clusters that can function as a collective or virtualised system capable of linear scaling as nodes are added.
With Sun Fire Link interconnect, Sun claims to have increased speeds at which data is shared, delivering bandwidth an order of magnitude greater than standard interconnects. It can handle 4.8Gbyte per second peak throughput and peak performance of more than a TeraFlop — one trillion floating-point operations per second — in a cluster of systems.
For the demands of high performance and technical computing (HPTC), applications that support MPI (Message Passing Interface), such as Sun HPC ClusterTools software, can run in a cluster and benefit from Sun Fire Link interconnect’s low latency and fast throughput.
It has a number of high availability features, including link striping, which enables the combination of up to four Sun Fire Link channels in parallel, in addition to hot-swap components.
Auto fail-over capabilities and triple redundancy are built into the design of the new interconnect technology via dual links per assembly, dual assemblies per system, all supported by dual switches.
