In order for firmware addons to be available, the administrator must first deploy the server vendor Hardware Support Manager (HSM) and import the appropriate server vendor bundle. This is explained in detail in the VMware documentation, specifically in the section titled "Deploy the Hardware Support Manager" in the "Using vSphere Lifecycle Manager" document.

The TRIM and UNMAP capability of vSAN is used to reclaim space on an all-flash vSAN cluster by discarding blocks that are no longer in use. In order to use this capability, the following prerequisites must be met:

• The VM guest operating system must support the ATA TRIM or SCSI UNMAP command. This will allow the guest OS to communicate with the vSAN datastore to inform it of blocks that are no longer in use.
• The vSAN cluster must be an all-flash architecture. TRIM and UNMAP can only be used on all-flash vSAN clusters, as it doesn't make sense on the hybrid vSAN cluster.

This is explained in VMware vSAN documentation in the section "vSAN Space Reclamation" Reference: https://docs.vmware.com/en/VMware-vSphere/7.0/vsphere-vsan-70-admin-guide/GUID-7E8F6C98-7C0B-4D21-8F1A-F3A3A9F4F4A4.html

A stretched cluster in vSAN requires a reliable, low latency Layer 3 communication from the data sites to the witness site. Therefore, an interruption of Layer 3 communication from the data sites to the witness site could cause a vSAN stretched cluster to fail. Additionally, blocked UDP ports on the firewall between data sites and high latency (RTT) of more than 5ms between data sites could also cause failure of the vSAN stretched cluster.

According to the VMware Official Guide, “Adding capacity drives increases the storage capacity of the disk group and the vSAN datastore. Adding a disk group to each host increases the storage capacity of the vSAN datastore.”

To add the vSAN Witness Appliance to the cluster as a host, the vSAN administrator can either deploy and configure the vSAN Witness Appliance OVA, or add the vSAN Witness Appliance ESXi host to the vSAN cluster.
