This is less than 1us per IOP. Interesting. Their hardware may not
actually support this. 10GbE typically is 7-10us, though ConnectX and some
others get down to 2ish.
Which I/O depth has been used in the test ? Latency matters most with
an I/O depth of one and is almost irrelevant for high I/O depth
Yes, but then they are measuring the efficiency of their
caching/queuing, and not of actual physical IOPs.
For one of our storage clusters at a customer site, we have demonstrated
really fast writes into cache across 8000+ simultaneous writers. Its
just that this number is ... well ... meaningless.
