    .Parameter VIServer
        [sr-en] IP address or the DNS name of the vSphere server to which you want to connect
        [sr-de] IP Adresse oder DNS des vSphere Servers

    .Parameter VICredential
        [sr-en] PSCredential object that contains credentials for authenticating with the server
        [sr-de] Benutzerkonto für die Ausführung

    .Parameter HostName
        [sr-en] Name of a host where you want to create the new datastore
        [sr-de] Hostname

    .Parameter StoreName
        [sr-en] Name for the new datastore
        [sr-de] Name des Datastore

    .Parameter Path
        [sr-en] If you want to create an NFS datastore, specify the remote path of the NFS mount point. 
        If you want to create a VMFS datastore, specify the canonical name of the SCSI logical unit that will contain new VMFS datastores
        [sr-de] Zum Erstellen des NFS-Datenspeichers, Remote-Pfad des NFS-Mount Point angeben
        Zum Erstellen des VMFS-Datenspeicherden kanonischen Namen der logischen SCSI-Einheit angeben

    .Parameter FileSystemVersion
        [sr-en] File system you want to use on the new datastore
        [sr-de] Dateisystem des datastores

    .Parameter NfsHost
        [sr-en] NFS host where you want to create the new datastore
        [sr-de] NFS Host des neuen Datastore

    .Parameter Kerberos
        [sr-en] By default, NFS datastores are created with AUTH_SYS as the authentication protocol. 
        This parameter indicates that the NFS datastore uses Kerberos version 5 for authentication
        [sr-de] Kerberos aktivieren

    .Parameter ReadOnly
        [sr-en] Access mode for the mount point is ReadOnly
