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. On the VTrak controller, connect a SAS data port or a SAS data/cascade
port to your SAS HBA card. See Figure 18.
2. Connect the data/cascade port (a subtractive-routed port) of the first E610s
or E310s to the data port (a table-routed port) on the second E310s.
3. Connect the remaining E610s or E310s controllers in the same manner.
You can cascade up to eight VTrak subsystems.
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.
