Crossing the 1 tb/s throughput threshold for object storage with NVMe drives

Fabric-wise, PCIe 4.0 offers 16 Gbit/s per lane, so a single PCIe x16 device would have 256 Gbit/s of bandwidth available (in each direction), and a single server could reach 1 Tbit/s with four NVMe devices on four PCIe slots. There is the overhead of 128b-132b encoding to be considered, but that's minimal (3%). There is also the overhead of PCIe packets to consider, but if the NVMe device supports large maximum payload sizes (1kB+) it should be minimal.

Are there PCIe 4.0 x16 NVMe devices commercially available?

Are there any architecture papers/blogs on re-designing software for very fast storage ?

Once storage is as-fast as memory, things change.

Please note: i am NOT referring to cpu-on-the-memory-chip architectures

Can someone please fix the title? I presume it means TB/s or Tb/s but I am not able to load the article now. Then delete my comment.

My question is whether this includes overhead of actually persisting the data and guaranteeing a certain SLA in terms of retrieving the data? Don’t get me wrong, this is a nice achievement and good luck to them if their objective is to build a storage company (I or my company has no need to store large amounts of data at high speed so no bias there) but there’s a difference between ingesting data at high speed and actually guaranteeing it’s going to be there in a year’s time despite potential storage drive failures and stuff.

This doesn't say what minio actually is. It also says the benchmark cost $1000 to run. Also since this is terabits it is about 120 gigabytes per second using 256 drives.

The key is “drives”, writing simultaneously across all you can get high throughput.
