SAS dual-port advantage for fault tolerance
SAS features dual porting for redundancy, eliminating single points of failure and allowing for higher reliability and performance. By installing a SATA drive with the QDA-SA into a dual-controller Enterprise ZFS NAS, the SATA drive can share these SAS dual-port advantages to ensure a high-availability, fault tolerant enterprise storage environment.
