Cascading DAS Connection
If you have multiple VTraks and want to manage them from the same SAS HBA
card in the Host PC, connect the VTraks in a cascade. See Figure 19.
To setup a cascading DAS connection:
1. Connect the SAS HBA card in the Host PC to either of the SAS ports, circle-
or diamond-icon) on the I/O module of the first VTrak.
Use a SFF-8088 4X to 4X external SAS cable (supplied with the VTrak).
2. Connect the remaining port on the same I/O module of the first VTrak to the
I/O module of the next VTrak.
Be sure to connect circle icon to diamond icon or vice versa.
Use a SFF-8088 to SFF-8088 SAS cable to connect the VTraks.
You can cascade up to four VTraks in this manner. You can mix J610s and J310s
units in the same cascade.
