To enable VMware VAAI on your NFS datastores, you need to install Synology NFS VAAI Plug-in on each ESXi host.
NFS VAAI Plug-in can be installed directly on an ESXi server from the command line, or through the VMware Update Manager (VUM).
System Requirements:4 Synology NAS running DSM 5.1 or later https://lnkd.in/bA4KABw
