Properties Description
Device Life Status
Displays the life status of the PCIe SSD. The device life status is
determined by the following attributes:
Percent Lifetime Used — This attribute is determined by the
elapsed time since the start of use (up to three years) or
percentage of total bytes written (TBW).
Write Protect Progress — This attribute is determined by the
reduction in number of available spare sectors. If the available
spare sectors are less than 10 percent of the original pool, the drive
enters read-only mode.
Possible values for the device life status are:
Drive Health Good — The drive is used within the TBW
specification. The drive health is good as sufficient spare blocks are
available. The drive health status is good if the values for percent
lifetime used and write protect progress is less than 100 percent.
Approaching Warranty Coverage Expiry — The drive is reaching
the specified TBW, indicating that it is close to the end of warranty
coverage. However, the drive will be functional as the number of
spare blocks available are still above the threshold for entering the
read-only mode. The drive approaches the warranty coverage
expiry if the value for percent lifetime used is greater than or equal
to 90 percent and that for write protect progress is less than the
threshold value, which is 90 percent.
Warranty Coverage Expired — The drive has reached the TBW
threshold and met the life expectancy specification. The drive is
functional as the number of spare blocks available are still above
the threshold for entering the read-only mode. But, the specified
data retention period (amount of time that data can be read from
the drive after TBW is reached) drops, if TBW specification is
exceeded and the warranty for the drive expires. The warranty
coverage for the drive expires if the value for percent lifetime used
is equal to 100 percent and that for write protect progress is less
than 100 percent.
Approaching Read Only — The drive is running out of spare
sectors and is reaching the read-only mode. However, the health
status of the drive is good and data retention is unaffected. The
drive is stated to be approaching the read-only mode if the value
for percent lifetime used is less than 100 percent and that for write
protect progress is greater than or equal to 90 percent.
Read Only — The drive is in read-only mode. Users must save
open files, if any, to another device and replace or remove the
device. If this scenario occurs within three years of the device
installation, this failure is covered under warranty. The drive is in
read-only mode if the value for percent lifetime used is less than
100 percent and that for write protect progress is equal to 90
percent.
Driver Version
Displays the version of the driver that is installed on the PCIe SSD
sub-system.
NOTE: Storage Management displays Not Applicable for
subsystem for which the driver version cannot be
obtained.
Remaining Rated Write Endurance
Displays information on the SSD renewal/replacement based on
the amount of write workloads. This field indicates the total
remaining programs or erase-cycles available on the SSD, based on
the cumulative specification of the total NAND (Negated AND or
NOT AND) Flash chips in the SSD.
