This can have a significant performance improvement for VMDKs on NFS but isn’t the default setting. From the Control Station, you can use this command to turn on the uncached write mechanism: <code>server_mount &lt;data mover name&gt; -option &lt;options&gt;,**uncached** &lt;file system name&gt; &lt;mount point&gt;</code> Be sure to review pages 99 through 101 of the VMware on Celerra best practices document for more information on the uncached write mechanism and any considerations for its use.</p> </blockquote>
