Users Guide
The following table lists the physical device properties for PCIe SSD.
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 
specication. The drive health is good as sucient 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 specied 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 specication. The drive is 
functional as the number of spare blocks available are still above the 
threshold for entering the read-only mode. But, the specied data 
retention period (amount of time that data can be read from the 
drive after TBW is reached) drops, if TBW specication 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 unaected. 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.
