Expansion Unit Deployment And Topology - Synology NAS HD6500 Hardware Installation Manual

Expansion Unit Deployment and Topology

HD6500 supports RX6022sas (60-bay) expansion units, providing seamless storage expansion when needed.
HD6500 also supports multipath I/O for better stability and performance. This section will guide you through
how to connect the expansion units to your Synology NAS. Please follow our instructions below strictly to avoid
system error.
Note:
• RX6022sas comes with two SAS expansion cables (100cm and 200cm). Please use the longer one to
connect the farthest expansion unit to your Synology NAS.
• The primary and secondary ports on the back of the HD6500 are marked by stickers.
To connect RX6022sas with HD6500
1 Connect one end of the expansion cable to the primary port of your HD6500 and the other to the expansion
port of RX6022sas. Make sure the release band of the cable faces rightward when plugging into the HD6500,
and that of the cable faces upward when plugging into RX6022sas; otherwise, the HD6500 and expansion unit
will not be correctly connected.
