Post over at Blocks and Files talking about the recently upgraded IDC InfiniBand predictions. IDC raised its compound annual growth rate projections from 29% in 2007-2011 to 51.5%.
The post closes with this observation
InfiniBand supporters point to InfiniBand being available here and now whereas Fibre Channel is stuck at a pedestrian 8Gbit/sec and 10GigE also being slower than InfiniBand, as well as not being lossless or having predictable data delivery times.
Because of this InfiniBand is a better bet as a converged network medium for server-to-server clustering and server-to-storage communications, particularly in a virtual blade server world, than 10gigE with Fibre Channel running over it (FCoE).
