High speed system area networks (InfiniBand). challenges and solutions
D. Cassaday, K. Dierling, I. Colloff, Daniel Fernando Garcia · 2005
Key issues/challenges/questions effecting IB and its adoption: • How will IB play with other IO interconnect and networking technologies (pcix, pci2.0, pciexpress, ethernet, fibre channel) • What role will IB play in future data centers. • What are IBs strengths and weaknesses compared to other interconnect technologies. • Why is the IB architecture so complex? • Some segments of the HPC community are interested in very large clusters (256 nodes and above). Are their special challenges building such clusters and how is the InfiniBand community addressing these?
