Table 4. Physical Device Properties
Properties Description
Name Displays the name of the PCIe SSD. The name comprises the bay
ID and the slot in which the PCIe SSD is installed.
State Displays the health state of the PCIe SSD.
Bus Protocol Displays the technology that the PCIe SSD is using.
Device Protocol Displays the device protocol of the physical device, such as Non-
Volatile Memory Express (NVMe).
Media Displays the media type of the physical disk.
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
specication. The drive health is good as sucient 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 specied 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 specication. The drive is
functional as the number of spare blocks available are still above the
threshold for entering the read-only mode. But, the specied data
retention period (amount of time that data can be read from the
drive after TBW is reached) drops, if TBW specication 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 unaected. 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
les, if any, to another device and replace or remove the device. If
