SAS Cascaded Storage
Serial Attached SCSI (SAS) 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
Data Path
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 Figures 17, 18, and 19 on the following pages.
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.
Management Path
To establish the management path:
1.
On the VTrak controller, connect the Management Port on each Controller to
your network switch. See page 31, Figure 19.
2.
Connect the Host PC's or Server's standard NIC to your network switch.
