Setting Space Reclamation and SSD Trim

 

Space Reclamation allows you to reclaim space from deleted files to increase free space for storage pools, while SSD Trim enables the SSD to handle garbage collection overheads and improves future Write performance.

Click  ”Global Settings” (the “setting” icon next to “?” on the top-right side of the screen) to enable the function and its schedule. You will see two settings for Space Reclamation and SSD Trim:

Auto reclaim and SSD trim schedule: the thin provisioning space reclamation will be started based on the schedule you set in order to reclaim space and increase free space for storage pools.
Schedule: Set the Space and Reclamation and SSD Trim schedule.

To Disable this, Go to Storage Manager ->Global Settings -> Space Reclamation and SSD Trim -> disable
