What interfaces support redundant controller in a JBOD?

The correct choice indicates that SAS and SATA interfaces support redundant controllers in a JBOD (Just a Bunch of Disks) configuration.

SAS, or Serial Attached SCSI, is designed for high-performance storage solutions and offers features such as redundancy and dual-port connectivity, which means each drive can connect to two different controllers. This capability is essential in a JBOD setup, as it enhances reliability and allows for failover options. In the event that one controller fails, the other controller maintains access to the drives, ensuring continuous availability of data.

SATA, on the other hand, stands for Serial ATA and is widely used for connecting hard drives and SSDs. While SATA doesn’t inherently support dual connectivity like SAS, JBOD systems using SATA can still implement redundancy at the level of the RAID controller or by using multiple controllers within the server architecture. This setup can be configured to allow redundancy and some level of controller failover.

The combination of SAS and SATA in a JBOD setting allows for flexibility in performance and capacity, making them suitable for different types of storage solutions while still offering options for redundancy through controller configurations.

Other choices, such as DVD and SSD or USB, do not typically relate to JBOD configurations and are unsuitable for the
