Frequently Asked Questions
What is a JBOD enclosure and how does it differ from a RAID array?
A JBOD (Just a Bunch of Disks) enclosure like the ARC-9224JS-TR2 provides raw storage expansion without built-in RAID functionality. Unlike RAID arrays, JBODs allow your host system or storage controller to manage data protection, offering flexibility for enterprise environments that require custom redundancy strategies or integration with existing storage management systems.
Can I mix 2.5" and 3.5" drives in the same 24-bay JBOD enclosure?
Yes, the ARC-9224JS-TR2 supports both 2.5" and 3.5" SAS or SATA drives within the same enclosure, allowing you to optimize capacity and performance based on your specific workload requirements. This flexibility makes it ideal for hybrid storage configurations.
What happens if a power supply or cooling fan fails in this 12Gb/s SAS JBOD?
The redundant hot-swappable power and cooling modules ensure continuous operation without downtime. If either component fails, the backup module automatically takes over, and you can replace the failed unit while the system remains online—critical for mission-critical storage environments.
How many ARC-9224JS-TR2 enclosures can I daisy-chain together?
The ARC-9224JS-TR2 supports daisy-chaining via its expansion ports, allowing you to connect multiple 24-bay JBOD enclosures to a single host controller. The exact number depends on your SAS expander topology and host controller capabilities; consult Areca documentation for your specific configuration.
