Two weeks ago, I wrote about The Data Center in the Age of Abundance and claimed that IOPS are – among other things – a solved problem.
What does a solved problem look like? Here is a benchmark running 100k random writes of 4K per second, with zero Jitter, at 350µs end-to-end write latency across six switches.
Databases really like reliably timed writes like these.
Maximum queue depth would be 48, the system is not touching that.
