Physical Device Properties
The following table lists the physical device properties for PCIe SSD.
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 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. NOTE: This option is applicable
to Micron PCIe SSDs, Non-Volatile Memory Express (NVMe) PCIe SSDs,
and SAS/SATA SSDs. |
Firmware Revision | Displays the firmware version of the physical device. |
Model Number | Displays the Piece Part Identification (PPID) of the PCIe SSD. |
Capacity | Displays the capacity of the device. |
Vendor ID | Displays the hardware vendor of the device. |
Product ID | Displays the product ID of the device. |
Serial No. | Displays the serial number of the device. |
PCIe Negotiated Link Speed | Displays the current negotiated transfer speed of the physical device in GT/s. |
PCIe Maximum Link Speed | Displays the capable transfer speed of the physical device in GT/s. |
PCIe Negotiated Link Width | Displays the current negotiated link width of the physical device. |
PCIe Maximum Link Width | Displays the capable link width of the physical device. |
Form Factor | Displays the form factor of the device. Possible
values are: Add-in Card — For HHHL devices 2.5 inches — For physical devices other than a HHHL device. |
Sub Vendor | Displays the vendor name of the device. |
Available Spare | Displays the threshold value set for all PCIe SSDs. The default value is 10%. |
