Cascading Das Connection - Promise Technology VTrak series Kurzanleitung

Cascading DAS Connection

To setup a cascading DAS connection:
1. Connect the SAS HBA card in the Host PC to the SAS IN port (with the circle
icon) on the first VTrak.
See Figure 12. Use a SFF-8088 4X to 4X external SAS cable (supplied with
the VTrak).
2. Connect the SAS OUT port (with the diamond icon) on the same I/O module
of the first VTrak to the SAS IN port (with the circle icon) on the second
VTrak.
Be sure to connect circle icon to diamond icon or vice versa.
You can cascade up to four VTrak units in this manner.
You can mix J830s and J630s units as well as J610s and J310s units in the
same cascade. Note that Jx10s are 3Gb units and might reduce data
throughput.
