Gauging the percentage of life remaining for SSDs

An SSD can be written and erased a limited number of times.

Through the SSD Life Left disk property, you can gauge the percentage of disk life remaining. This value is polled every 5 minutes. When the value decreases to 20%, an event is logged with Informational severity. This event is logged again with Warning severity when the value decreases to 5%, 2% or 1%, and 0%. If a disk crosses more than one percentage threshold during a polling period, only the lowest percentage will be reported. When the value decreases to 0%, the integrity of the data is not guaranteed. To prevent data integrity issues, replace the SSD when the value decreases to 5% of life remaining.

Under Maintenance > Hardware within the PowerVault Manager, select the SSD. See the SSD Life Left label under Disk Information to view the percentage of SSD life remaining. To view the percentage of SSD life remaining using the CLI, enter the show disks CLI command with the detail parameter as described in the CLI Reference Guide.
