TL-R1620Sdc | Dual-controller SAS 12Gb/s storage expansion for enterprises
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.
- 1Flexibly and economically expand the storage space of a dual-controller QNAP NAS for petabyte-level storage capacity.
- 2Dual path mini-SAS design with a redundant power supply for enhanced system reliability.
- 3QNAP dual-controller NAS can detect JBOD connections, and enter missing mode protection to prevent data corruption.
- 4DataBolt™ bandwidth optimization combines two 6Gb/s connections into one 12Gb/s data stream to achieve faster speed with existing 6Gb/s infrastructure.
- 5Manage the storage space and settings of the connected TL-R1620Sdc with Storage Manager on the host NAS.
- 6The 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.
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 SAS 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.
Supports SAS DataBolt™ technology, delivers 12Gb/s speed using existing 6Gb/s infrastructure
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.
