Configuring Cascaded Storage
Cascaded storage requires:
• One SAS HBA card in the Host PC or Server
• A network switch
• A network interface card (NIC) in the Host PC or Server
To establish the data path:
1. Connect a SAS data port or a SAS data/cascade port on the VTrak controller
to your SAS HBA card. See Figure 18.
2. Connect the remaining port of the first VTrak to the next VTrak.
Be sure to connect circle icon to diamond icon or vice versa.
3. Connect the remaining VTrak controllers in the same manner.
You can cascade up to eight VTrak subsystems.
Be sure to connect circle icon to diamond icon or vice versa.
To establish the management path:
1. On the VTrak controller, connect the Management Port on each Controller to
your network switch. See Figure 19.
2. Connect the Host PC's or Server's standard NIC to your network switch.
