VTrak J610s, J310s Quick Start Guide
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.
