Re: IBM Summit - 2.4x more storage nodes, 3.2x more NVMe Drives, 12.5x more memory, 5% faster
The benchmark is all about performance per client, which is a different metric.
Exactly. Your system did perform very well on that benchtest, no question about that (congrats, btw). The standard issue about benchmarks still applies: they are only indicative of real-world performances if your real-world needs are reasonnably close to the test conditions, which is, I guess, the point that many here are trying to make.
you can see that WekaIO did over 2x the bandwidth of Spectrum scale (27GIB/sec vs. 9.8GIB/Sec)
Analogies are always imperfect, but the bandwidth metric kinda reinforces this particular one: while the motobike is very fast, it's not necessarily able to process large loads faster than a lorry (although in that case a better analogy would probably be "one Hayabusa vs a fleet of delivery scooters" but that doesn't remotely sound as good).
