The race between InfiniBand and Ethernet begins anew. As reported on Channel Register, since the first 10Gb/sec InfiniBand products hit the market in 2001, it’s InfiniBand, more than Ethernet, that has kept pace with the exploding core counts in servers and massive storage arrays to feed them.
Now the race between InfiniBand and Ethernet begins anew. As El Reg previously reported, the IEEE has just ratified the 802.3ba 40Gb/sec and 100Gb/sec Ethernet standards, and network equipment vendors are already monkeying around with non-standard 100Gb/sec devices. At the SC09 supercomputing conference last fall, Mellanox was ganging up three quad data rate (QDR, at 40Gb/sec) InfiniBand pipes to make a twelve-port 120Gb/sec switch. This latter box is interesting, but it is not adhering to the current InfiniBand roadmap.
