Extended Idle Period with a Burst of Random Write
|
||
|
|
consists of five minutes of idle followed by
|
||
|
|
thirty-two random write commands of size 1 MiB
|
||
|
|
submitted to a single controller while all other
|
||
|
|
controllers in the NVM subsystem are idle, and then
|
||
|
|
thirty (30) seconds of idle.
|

|
|
.IP "NVME_PSD_WORKLOAD_2" 12
|
||
|
|
Heavy Sequential Writes consists of 80,000
|
||
|
|
sequential write commands of size 128 KiB submitted to
|
||
|
|
a single controller while all other controllers in the
|
||
|
|
NVM subsystem are idle. The submission queue(s)
|
||
|
|
should be sufficiently large allowing the host to
|
||
|
|
ensure there are multiple commands pending at all
|
||
|
|
times during the workload.
