 VMware [vSAN](https://techdocs.broadcom.com/us/en/vmware-cis/vsan/vsan/8-0/release-notes/vmware-vsan-803-release-notes.html) ESA (Express Storage Architecture) has enhanced capabilities that are configured by default with each Azure VMware Solution deployment, and each cluster utilizes its own high-performance vSAN ESA datastore. Below are the Azure VMware Solution SKUs that support vSAN ESA as the default architecture type, with the following configurations per cluster:

 ## Supported host types
 
 vSAN ESA (Express Storage Architecture) is supported on the following Azure VMware Solution host types:
 
-- AV48
-
+- AV48 (Korea Central)
 
 ## Set VMware vSAN TRIM/UNMAP
 
-Guest Trim/Unmap is enabled by default and cannot be disabled for cluster with vSAN ESA. Run command Set-AVSVSANClusterUNMAPTRIM is not applicable for vSAN ESA based clusters.

+> [!NOTE]
+> vSAN TRIM/UNMAP is enabled by default on vSAN ESA based clusters. To disable UNMAP at the VM level, the following other requirements are needed for it to function as intended.
+> - All VMs in vSAN ESA clusters are set by default to use UNMAP inherited from the cluster level. UNMAP can be disabled using the disk.scsiUnmapAllowed flag with a value of 'false' at the virtual machine level, should you wish to disable this behavior on a per-VM basis. VMX file changes require a reboot to take effect.
+- The guest operating system must be able to identify the virtual disk as thin.

 ## Set VMware vSAN Space Efficiency
 
-In vSAN ESA (Express Storage Architecture), compression is enabled by default on the cluster.
