TL-R1620Sdc

Dual-controller SAS 12Gb/s storage expansion for enterprises

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.

Dual controllers: JBOD HA protection

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.)

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.

Storage Management

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.

Leverage the 6Gbps SAS to SATA drive adapter to install 2.5-inch SATA SSDs

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.
