SCSI still does have some tricks (eg VAAI) which I don't think have NVMe counterparts yet?
Still, even just being able to get rid of the huge complexity and historical baggage of SCSI is a good thing. One of my favourite examples is how the spec defines the LUN number to not be a number.
- wtallis 5y agoI think NVMe is pretty close to feature parity with SCSI, or at least the subset of SCSI that is actually relevant. NVMe includes thin provisioning, some copy offload, atomic operations and of course deallocate/trim—which I think covers all the VAAI features.
