QNAP TL-R1620Sdc 16 Bay Rack Enclosure

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. Key Product Info Flexibly and economically expand the storage space of a dual-controller QNAP NAS for petabyte-level storage capacityDual path mini-SAS design with a redundant power supply for enhanced system reliabilityQNAP dual-controller NAS can detect JBOD connections and enter missing mode protection to prevent data corruptionDataBolt bandwidth optimization combines two 6Gb/s connections into one 12Gb/s data stream to achieve faster speed with existing 6Gb/s infrastructureManage the storage space and settings of the connected TL-R1620Sdc with Storage Manager on the host NASThe space-efficient short depth design makes it easy to install in small media cabinets or places with a lot of cabling Product Features . Failure-resistant with a dual-controller dual-path designConnect 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. Highly efficient reliable and scalableThe 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 infrastructureFeaturing 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. Leverage the 6Gbps SAS to SATA drive adapter to install 2.5-inch SATA SSDsWhile 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. .
