Qnap TL R1620Sdc 16Bay 3U Rackmount storage expansion, TL R1620Sdc | Asashi Technology Sdn Bhd (332541-T)

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.

Storage expansion for dual-controller NAS

Flexibly and economically expand the storage space of a dual-controller QNAP NAS for petabyte-level storage capacity.
Dual path design

Dual path mini-SAS design with a redundant power supply for enhanced system reliability.
Missing mode protection

QNAP dual-controller NAS can detect JBOD connections, and enter missing mode protection to prevent data corruption.
DataBolt™ bandwidth optimization

DataBolt™ bandwidth optimization combines two 6Gb/s connections into one 12Gb/s data stream to achieve faster speed with existing 6Gb/s infrastructure.
Flexible storage management

Manage the storage space and settings of the connected TL-R1620Sdc with Storage Manager on the host NAS.
Short depth design

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 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.
