The J300Q 6Gb SAS-to-SAS JBOD enclosure supports both SAS and SATA-II drives, providing high availability as well as cost advantages for small and medium business.
J300Q 6G SAS-SAS JBOD system is specially designed for high availability applications. The J300Q is well equipped with fully redundant components for all major functions, including redundant JBOD controllers, power supplies, fan modules, and SAS JBOD expansion ports. Being hot pluggable, all of them provide non-stop services. Distinct from others, J300Q is able to upgrade firmware without system down time. And in case of multiple hardware failures as shown below, Qsan’s design of dual paths between Qsan RAID systems and JBOD systems will still provide services; while other vendors will not be able to provide any service.
All J300Q systems are equipped with Qsan’s default green features for power saving. In most cases, the hard drives consume most power. With the auto disk spin down feature and proper configuration (with Qsan Q Series High Availability RAID Systems), the power consumption of hard drives can be reduced to a minimum, and users will not even notice this feature. J300Q monitors the environment temperature for cooling mechanism and the fan modules respond accordingly. The power supply modules are all 80 PLUS power efficient for better power converting rate. In virtue of the reduction of hard drive power consumption, the advanced cooling mechanism, and the energy-efficient power supplies, the unnecessary power cost is decreased greatly.
