VTrak J300s Quick Start Guide
Cascading DAS Connection
If you are using multiple J300s units and want to manage them from the same
SAS HBA card, connect the J300s units in a cascade.
Connect the SAS HBA card in the Host PC to the table-routed port (CN1) of the
I/O module. Use a SFF-8470 4X to 4X external SAS cable with thumbscrew
connectors (supplied with the J300s unit).
Connect the I/O module's subtractive-routed ports (CN3) on the first J300s unit to
the table-routed port (CN1) on the next J300s unit. You can cascade up to four
J300s units in this manner.
