RAID driver would use it as a retarded object store based block device.
The absolutely last thing that any fs designer would want is to outsource to hardware vendor implementation of anything other than a basic operation. We already saw this in hardware RAID which sucks donkey balls compared to software RAID.
This is a pure value add play in a commodity market.
- mpsys 7y agoKV-SSD replaces the filesystem with Abstract Device Interface(ADI), that sits between the KV API exposed to the applications directly and the KV device driver. According my understanding, although some modern filesystems combines RAID and the file system, these are separate independent abstractions. However, it would be interesting to explore how RAID will work with KV-SSDs. You can take a look at a commercial implementation of Samsung's Mission Peak system to benchmark KV-SSDs (I am not sure whether the following one is an officially approved implementation or not) - https://www.broadberry.com/performance-storage-servers/cyberstore-136nf1-nvme-ssd https://www.broadberry.com/performance-storage-servers/cyber...
