QNAP TL-R1620Sdc 16-Bay, 3U Rack-mountable Expansion Unit

Featuring dual controllers, an OLED indicator, and a short-depth rackmount design, the 3U 16-bay QNAP 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 out of stock and facing manufacturing delays. We have now stopped taking orders because of supply uncertainty. When availability of the SAS chipset stabilizes, we will evaluate the market demand again.

  • 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.)

Failure-resistant with a dual-controller, dual-path design

Connect the QNAP 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.

Connect up to 7 expansion units for petabyte-level storage capacity

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 PCIe-based expansion card.

Highly efficient, reliable and scalable

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.
