-After vSAN TRIM/UNMAP is Enabled, the following lists additional requirements for it to function as intended. Once enabled, there are several prerequisites that must be met for TRIM/UNMAP to successfully reclaim no longer used capacity.
+After vSAN TRIM/UNMAP is enabled, you must meet certain prerequisites in order for the command to function as intended and successfully reclaim unused capacity. The VM-level prerequisites are:
 
-- Prerequisites - VM Level
 - Virtual machine hardware version 11 or later for Windows.
 - Virtual machine hardware version 13 or later for Linux.
-- `disk.scsiUnmapAllowed` flag isn't set to `false`. The default is implied `true`. This setting can be used as a *stop switch* at the virtual machine level. You can use this setting if you want to disable this behavior on a per-VM basis and don't want to use in-guest configuration to disable this behavior. VMX file changes require a reboot to take effect.

VMX file changes require a reboot to take effect.
 - The guest operating system must be able to identify the virtual disk as *thin*.
 - After you enable a VM at a cluster level, it must be powered off, and then powered back on (a reboot is insufficient).

 ## Set VMware vSAN space efficiency
 
 To set your preferred space efficiency model, run the `Set-vSANCompressDedupe` cmdlet.

-   > Changing this setting causes a vSAN resync and performance degradation while disks are reformatting.
-   > Assure that you have enough available space when you change to the new configuration. We recommend that you have at least 25% available space.

 Learn more about the `Set-vSANCompressDedupe` cmdlet:
 
-- When you set `Compression` to `False` and `Deduplication` to `True`, vSAN is set to `Deduplication` and `Compression`.
-- When you set `Compression` to `False` and `Deduplication` to `False`, all space efficiency is disabled.
+- When you set `Compression` to `false` and `Deduplication` to `true`, vSAN is set to `Deduplication` and `Compression`.
+- When you set `Compression` to `false` and `Deduplication` to `false`, all space efficiency is disabled.
 - The default settings for Azure VMware Solution are `Deduplication` and `Compression`.
 - The `Compression` setting provides only slightly better performance.
 - When you disable both the `Compression` and `Deduplication` settings, you can achieve the greatest performance gains, but at the cost of space efficiency.
