NVME_CDW11_FEATURE_NON_OPERATIONAL_POWER_STATE union (nvme.h)

Contains parameters for the Volatile Write Cache Feature that controls the volatile write cache, if it is supported and present, on the controller.

Note

If the controller is able to guarantee that data present in a write cache is written to non-volatile media on loss of power, then that write cache is considered non-volatile and this setting does not apply to that write cache. In that case, this setting has no effect.

The values from this structure are used in the VolatileWriteCache field of the NVME_CDW11_FEATURES structure.
