Yes, the MPI ping-pong latency I measured between x2200s was the lowest I ever saw for 1GbE. However, the motherboards in them were a disaster area (unlike any other Sun kit I ever saw).
- bayindirh 4y agoUnfortunately we were never able to procure SPARC based systems since we are running general purpose clusters, however we were able to get some Sun ZFS 74xx series storage. We had its smaller sibling 7320 for testing for some time. I was lucky to make the benchmarks and tests on that, and it was unbelievable for its size, so we got its bigger sibling with a pretty hefty configuration. It had a dtrace based zero overhead real-time monitoring dashboard and, the insights and optimization possibilities were unbelievable for a device of that era. It was basically a proper enterprise storage with all the interfaces, bells and whistles with the practicality of a home desktop NAS device. Select LUN, select capacity & disk config, select share strategy, select interfaces and it's done. The fun part? It was able to saturate any interface on itself, incl. Infiniband.
