NVMe 2.0? This is the first I've heard of it. A quick google search reveals a very few mentions of it, but no summaries or any concrete info about what's proposed. Anyone know more?
The main reason why they're jumping to 2.0 instead of calling it 1.5 is that they're reorganizing the spec to be more modular. There will be a base spec, separate specs for each command set (block IO, zoned, key-value), and separate specs for each transport (PCIe, RDMA, TCP). Aside from that reorganization, in terms of new functionality 2.0 won't be much larger than usual. So far, they've ratified and published 8 Technical Proposals defining new functionality on top of 1.4.
2021: Your storage gumstick runs an embedded ARM CPU that is powerful enough to run Linux decently well in its own right, sending data to your ARM main CPU via the ARM secure encryption chip on your Apple laptop, pulling data from an ARM-equipped datacentre, while you talk on your ARM CPU powered high-spec phone, driving your car stuffed full of ARM chips, while munching on a sandwich from your ARM-embedded toaster as your ARM-chipped fridge orders more cheese for tomorrow.

I see you've now written more about some NVMe 2.0 proposals. Thanks!https://www.anandtech.com/show/15959/nvme-zoned-na...

So much vertical integration will surely cost customers an ARM and a leg.
