JBOD System
Quick Start Guide
Expanding JBOD Enclosures
You can expand a maximum of seven JBOD enclosures to a RAID system.
Figure 1-1 shows a RAID system with three JBOD enclosures in a loop. The
loop connection works to ensure the system can continue with its
operation without interruption even if any of the JBOD fails. Once a JBOD
fails, the other two can still continue to transmit data around the loop via
the redundant path.
