Physical Device Properties
You can view information about PCIe SSDs and run PCIe SSD tasks on the Physical Device Properties
page. To view the complete PCIe SSD properties, click Full View on the top of the page.
The following table lists the physical device properties for PCIe SSD.
Table 5. 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.
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 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
