Add bays without migrating

An expansion unit connects over eSATA or Infiniband and appears as extra bays in DSM. You can extend an existing storage pool across it or keep it as a separate pool for backups. DX517 and DX525 pair with DiskStation Plus models, RX418, RX426 and RX1223RP with RackStation, RXD1219sas and RX1222sas with the SA series, FX2421 with FlashStation. Each listing names the hosts it supports.
