Note	Connecting to a Synology FlashStation FS3017 requires the optional FS3017 Expansion Card (FXC17) to be installed on the host device. FS3017 Expansion Card is sold separately. To have better performance, we recommend creating storage volumes physically located within the same NAS or Expansion Unit, rather than creating volumes across your NAS and Expansion Unit.
