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. Although SATA 6Gbps SSDs provide high-performance and affordable storage, the lack of dual-port support makes them unsuitable for dual-controller environments. By installing a SATA SSD with the QDA-SA2 into a dual-controller Enterprise ZFS NAS or a dual-controller server, the SATA SSD can share these SAS dual-port advantages to ensure a high-availability, fault-tolerant enterprise storage environment.

Designed for dual-controller servers and Enterprise ZFS NAS

The QDA-SA2 can be easily installed in a dual-controller Windows®/Linux® SAS server and the 3.5-inch disk tray of an Enterprise ZFS NAS (Disk tray model: SP-ES-TRAY-WOLOCK). (QES 2.0.0 (or later) is required for the NAS)

Note:
1. QDA-SA2 does not support SSD TRIM and the drive S.M.A.R.T. feature is not supported on non-QES operating system.
2. The QDA-SA2 is not compatible with Windows®/Linux® servers that use Broadcom® RAID Controller Cards.
