Why switch to infiniband? Ethernet can go just as fast (not as good of latency) and the cables are cheap and ubiquitous. The only thing stopping higher speeds is cost. I have been watching 10GbE PCI-E cards for the last year or two and they have dramatically dropped in price ($200 from newegg). You can get server motherboards with 2 integrated 10GbE ports for $500 as well. 10GbE does run over cat6 by the way.
- mattzito 12y agoI think for general-purpose workloads, it's not relevant. However, some of the IB-specific capabilities like RDMA are extremely interesting for clustering use cases. You can dramatically reduce the overhead of moving data around between nodes by bypassing the kernel entirely.
- reportingsjr 12y agoI understand that sort of use case, but this article is asking about desktop computers. It almost seems like the author only sees it used in high performance situations so clearly it is better for all situations.
