Frequently Asked Questions
What is a SAS 12G JBOD and why do I need one?
A SAS 12G JBOD (Just a Bunch of Disks) is a storage enclosure that expands your server's storage capacity without RAID complexity. The RS212X12 provides 12 bays of direct-attached storage with 48Gb/s bandwidth, ideal for applications requiring massive capacity with simple management and maximum performance.
Can I mix different drive types in the RS212X12?
Yes. The 12 bay SAS expander supports both SAS and SATA drives at 12Gb/s speeds, and is fully backward compatible with 6Gb/s SAS and SATA drives. This flexibility allows you to optimize your storage mix based on performance and budget requirements.
How many drives can I connect with daisy-chaining?
The built-in SAS expansion port enables you to daisy-chain multiple RS212X12 units together, supporting up to 256 total drives across the chain. This scalability makes it perfect for growing storage demands without replacing infrastructure.
Why is redundant power supply important for a JBOD enclosure?
Redundant power supply ensures continuous operation even if one power supply fails, eliminating single points of failure. This is critical for enterprise environments where storage availability directly impacts business continuity and data access.
