Description
0
Critical Warning
: This domain indicates a critical warning about the controller
status. Critical warnings are returned to the host through asynchronous events.
Bit
Description
0
Value
1
indicates that the redundant space is smaller than the
threshold.
1
Value
1
indicates that the temperature is higher or lower than a critical
threshold.
2
Value
1
indicates that the component reliability is reduced due to a
critical media error.
3
Value
1
indicates that the media is read-only.
4
Value
1
indicates that the non-volatile component of the controller
fails. This domain is valid only when the controller is integrated with
a non-volatile component.
7:5
Reserved
2:1
Temperature
: indicates the overall component temperature in unit of Kelvin. An
asynchronous event is reported to the host when the temperature exceeds the
threshold.
3
Available Spare
: indicates the percentage (0 to 100%) of the available redundant
space.
4
Available Spare Threshold
: indicates the threshold of the available redundant
space. An asynchronous event is reported to the host when the available redundant
space is smaller than the threshold.
5
Percentage Used
: indicates the ratio of the used life to the preset life. 100 indicates
that the component has reached the preset life, but may still function properly. The
value can be greater than 100. The value is always set to 255 if it is greater than
254.
31:6
Reserved
47:3
2
Data Units Read
: indicates the number of 512-byte sectors read from the controller
by the host. 1 indicates that the host has read 1000 512-byte sectors, which do not
include metadata. If an LBA is not 512 bytes, the controller converts it into 512-
byte sectors (hexadecimal) for calculation.
63:4
8
Data Units Written
: indicates the number of 512-byte sectors read into the
controller by the host. 1 indicates that the host has written 1000 512-byte sectors,
which do not include metadata. If an LBA is not 512 bytes, the controller converts
it into 512-byte sectors (hexadecimal) for calculation.
79:6
4
Host Read Commands
: indicates the number of read commands sent to the
controller.
