Configuring JBOD Expansion
To expand the number of disk drives:
1. On the E310f controller, connect the SAS connector (a subtractive-routed
port) to CN1 (a table-routed port) on the I/O module of the first J300s unit.
See Figure 13.
2. Connect CN3 (a subtractive-routed port) on the first J300s unit to CN1 on
one of the I/O modules of the next J300s unit.
3. Connect the remaining J300s units in the same manner.

You can expand a SAN system with no single point of failure. See Figure 14.
Such an arrangement requires:
• Two Fibre Channel switches
• Two Fibre Channel HBA cards in each Host PC or Server
• A network switch (not shown)
• A network interface card (NIC) in each Host PC or Server
