Explanation
When files are deleted inside a virtual machine, the guest OS may not immediately inform the underlying storage that blocks are free. By enabling TRIM/UNMAP on the vSAN cluster, the guest OS can communicate unused space back to vSAN, allowing it to reclaim and free up storage capacity. This feature ensures that the reported space usage on the datastore accurately reflects actual data stored after deletions.
