As fibre cables are being dropped into both oceans it’s obvious dissemination is an ‘issue’ and large data sets enhance the challenge. Suggest checking out Obsidian Strategics’s Longbow, capable of extending InfiniBand on a global scale. The future of Ethernet as ‘the acceptable standard’ … hmmm.

An excellent article. You do a good job of not only educating the less informed but also provides good raw meat for those of us that have been riding the IB train for over a decade. My only suggestion is as the anticipated drive toward clustered ARM64 servers becomes a reality, it might also be useful to start to keep an eye on RapidIO.

I was aware of that mode to golden screwdriver the 40GE up to 56GE. It could be that Microsoft is not buying all of its 40GE switches from Mellanox, or it didn’t want to pay the upgrade fee.

For example, is (and why) Microsoft running it’s Azure cloud storage at 40GbE rather than 56GbE since it’s already using Mellanox switches?
