QDA-SA2

Features

The QDA-SA2 adapter is designed for dual-controller servers and QNAP Enterprise ZFS NAS and allows the use of a 2.5-inch SATA 6Gbps SSD in a 3.5-inch SAS drive bay. It can be installed in a QNAP NAS or server (Windows®, Linux®) – providing the capacity to replace an expensive SAS drive with a more-affordable yet high-performing SATA SSD.

Note: QDA-SA2 adapters are sold in a pack of four. (Order number: QDA-SA2-4PCS)

1
Use more affordable 2.5-inch SATA SSD in a 3.5-inch SAS drive bay. (SSD sold separately)
2
Up to 6 Gb/s file transfer speeds.
3
The installed SATA SSD can share SAS dual-port advantages for higher reliability.

Note: The connected drive may not reach its optimal performance due to protocol translation and some overhead.

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.
