The IBTA increased data speeds for 2011 due to the increased demand for higher throughput and to provide the base for next-generation, high-performance and data centre interconnect solutions.
"The new projected speeds will provide end users with enhanced cost/performance benefits and robust network capabilities to support multi-core processors and accelerators", stated Jim Pappas, marketing director at Intel Corporation and co-chair of the IBTA Steering Committee. "The roadmap reiterates the IBTA's commitment to continue and define InfiniBand as the performance expert in interconnects, while ensuring end user investment protection."
In addition to the roadmap, the IBTA unveiled a new naming convention for bandwidth that expands the previously-defined terms - DDR, QDR, EDR and HDR - to include FDR and NDR. FDR (14Gb/s data rate per lane in 2011) was added for midrange enterprise data centre solutions that are looking to optimize the cost and power/performance ratio for their communications networks.
The roadmap details 1x, 4x, 8x and 12x EDR and FDR, incorporating 64/66 encoding, with bandwidths reaching 300Gb/s data rate EDR in 2011. The newly defined link speeds are designed to keep the rate of performance increase in line with systems-level performance increases.
For vendors with a stake in the interconnect business, the InfiniBand roadmap provides a vendor-neutral outline for the progression of InfiniBand so that they may plan their product development accordingly. For enterprise and high-performance computing end users, the roadmap provides specific milestones around expected improvements to ensure their InfiniBand investment is protected.

The IBTA also announced that InfiniBand is the only growing standard interconnect technology on the June 2010 TOP500 list of supercomputers. InfiniBand is connecting 208 systems of the TOP500, or 41.6 percent. This represents a 37 percent increase from the list published one year ago.
InfiniBand is the most prevalent interconnect in the TOP100, TOP200 and TOP300, connecting the most powerful clusters in the world:
