Datacenter NVMe SSD Specification v2.0r15 question


 

OCP – Storage,

 

The Spec states "The active command counters count Read commands, Write commands, and De-Allocate/TRIM commands which exceed a configured latency threshold.".

 

Samsung would like clarity if the count is independent of the status code of the command completion (i.e. includes aborted and error) or if the count is only for commands that complete successfully.

Mike,

 

This is independent of the command status code so things like error and abort should be considered for these commands.
