Whereas the much-snubbed Infiniband protocol has gained purchase in high-performance computing, in the lower tiers vendors favor Fibre Channel and iSCSI. But that’s a pity, Mario Apicella writes, because “Infiniband could very well be the ultimate server connectivity protocol — at least for the time being.” Is Infiniband back from the dead again? “My guess is yes, but only for as long as its current bandwidth advantage will continue. 100-Gigabit Ethernet could be the death sentence for Infiniband, but I don’t see that coming on too fast.”
