Featuring dual controllers, an OLED indicator, and a short-depth rackmount design, the 3U 16-bay TL-R1620Sdc SAS 12Gb/s storage expansion enclosure is ideal for expanding the storage capacity of dual-controller QNAP NAS. Both controllers have three Mini-SAS HD (SFF-8644) ports, supporting 12Gbps SAS and Broadcom® SAS DataBolt™ bandwidth optimization technology. The dual path mini-SAS design sustains continuous operations even if an external JBOD cable is disconnected. Up to 7 TL-R1620Sdc units can be daisy-chained via high-speed Mini-SAS HD cables, providing scalability and high reliability for mission-critical storage of file servers, virtualization, surveillance, medium-sized data center, multimedia, and more.
Notice: Due to global chip shortages, this product is of limited availability.
Flexibly and economically expand the storage space of a dual-controller QNAP NAS for petabyte-level storage capacity.
Dual path mini-SAS design with a redundant power supply for enhanced system reliability.
QNAP dual-controller NAS can detect JBOD connections, and enter missing mode protection to prevent data corruption.
DataBolt™ bandwidth optimization combines two 6Gb/s connections into one 12Gb/s data stream to achieve faster speed with existing 6Gb/s infrastructure.
Manage the storage space and settings of the connected TL-R1620Sdc with Storage Manager on the host NAS.
The space-efficient short depth design makes it easy to install in small media cabinets or places with a lot of cabling. (Rail kit RAIL-B02 requires optional purchase.)
Connect the TL-R1620Sdc to a dual-controller QNAP NAS and create a redundant cross loop configuration that provides expansion units with redundant paths to the base NAS and protection between JBOD connections. If one or more paths to the TL-R1620Sdc disconnect, other expansion units can still communicate with the base NAS. This is essential for intermachine data protection and capacity scalability for uninterrupted mission-critical enterprise tasks.
The base NAS requires QES 2.1.1 (or later) and either Mini-SAS HD (SAS 12Gb/s SFF-8644), Mini-SAS (SAS 6Gb/s SFF-8088) ports or a .

The TL-R1620Sdc is powered by a low-power 28nm SAS35x28R SAS Expander and supports 12/6 Gb/s SAS/SATA drives. Both controllers have three Mini-SAS HD (SFF-8644) ports, and each SAS wide port combines four SAS 12Gb/s channels for up to 48Gbps bandwidth.
Multi-path protection: Yes
Performance: 48Gbps
(Two mini-SAS cables (SFF-8644 to SFF-8644) are included in the package. It requires option purchase of cables based on different ways of JBOD connection.)
Featuring Broadcom® SAS DataBolt™ bandwidth optimization technology, the TL-R1620Sdc has an intelligent data buffer for transferring data to drives at speeds that match the performance of the host NAS. Whether the TL-R1620Sdc uses 12Gb/s or 6Gb/s drives, the NAS host will transfer data to the TL-R1620Sdc at 12Gb/s, allowing you benefit from high-speed 12Gb/s SAS transmission with existing 6Gb/s infrastructure.
Simply connect a TL-R1620Sdc to a dual-controller QNAP NAS and power it on. The NAS will detect the drives in the TL-R1620Sdc as newly-installed local drives. By using the Storage Manager app on the host NAS, you can configure and manage the TL-R1620Sdc’s storage space by setting RAID groups, storage pools and snapshots. The TL-R1620Sdc can also be configured as the storage volume of the host NAS, allowing you to easily expand NAS storage to accommodate massive data or backup files.
While SATA 6Gb/s SSDs provide high-performance yet affordable storage, the lack of dual-port support makes them unsuitable for dual-controller environments. The QDA-SA2 adapter allows the use of a SATA 6Gb/s drive in a 3.5-inch SAS drive bay - providing the ability to expand storage capacity by using cost-effective SATA drives. By installing a SATA drive with the QDA-SA2 into the dual-controller TL-R1620Sdc, the SATA drive can share these SAS dual-port advantages to ensure a high-availability, fault-tolerant enterprise storage environment.
