Configuring JBOD Expansion
To expand the number of disk drives:
1. On the E610f or 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 14.
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.
Figure 14. JBOD data connections. The E310f is shown. The E610f is
similar
You can expand a SAN system with no single point of failure. See Figure 15.
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
