Datera's storage tiers
They show how useless it is by the way it fits in their tiers:
1. Intel Optane with >500,000 IOPS and <50 microseconds latency
2. Flash with 100,000 IOPS and <500 microseconds latency
3. Disk drives with 150 IOPS and multi-millisecond latencies
Why have two tiers that are so close to each other? It is like when array makers tried to push two hard drive tiers on us after they added flash, where the difference between 15K SAS/FC and big slow SATA was so small. Even when you adjust it for IOPS per GB it was only 10x - simply not enough to matter when flash was several orders of magnitude faster.
Optane is in the same boat, being at best 10x faster (but because of its low capacity, very similar on IOPS per GB) so it doesn't make sense as a third tier.
Storage is still a two tier world, hard drives for cheap bulk storage, and flash for fast / high IOPS storage. Eventually they'll be able to make cheap flash (QLC perhaps) with pretty poor write lifetime but when it gets close enough to hard drives in $/GB that will become the bottom tier. It won't be the bottom tier because of speed (though it may be slower also) but because of the low write lifetime. It will be where you put your cold data that is written rarely and may or may not be read often.
I think Datera is trying to hype Optane because 1) they were dumb enough to design it into their products and 2) as a startup they need all the press they can get, so they've hitched their wagon to Intel to try to grab a bit of the reflected attention on Optane.
