“For mission-critical enterprise environments, we recommend using a dual-controller NAS with dual-controller TL-R1620Sdc JBOD units to establish a reliable IT base with future-proof scalability”, said Jason Hsu, Product Manager of QNAP, adding “The dual-path architecture ensures failure resistance to fulfill uninterrupted mission-critical enterprise tasks and continuous business services.”
The TL-R1620Sdc uses a low-power SAS Expander and both controllers have three Mini-SAS HD (SFF-8644) ports. Each SAS wide port combines four SAS 12 Gb/s channels for up to 48 Gbps bandwidth. The space-efficient short depth design makes it easy to install in standard or small server racks. The TL-R1620Sdc can accommodate sixteen 12 Gb/s or 6 Gb/s SAS drives and supports QNAP’s QDA-SA2 adapter for installing 2.5-inch SATA drives that can share SAS dual-port advantages, providing businesses with a cost-effective option for storage expansion in fault-tolerant storage environments.
The TL-R1620Sdc can be used with QES-based dual-controller QNAP NAS and managed using the Storage Manager for JBOD storage management, such as setting RAID groups, storage pools and snapshots. The host NAS storage capacity can easily grow with business needs to accommodate massive data or backup files.
Host Windows servers with SAS HBA PCIe cards can connect to the TL-R1620Sdc and configure S2D (Storage Space Direct) failover clusters to enable scaling compute/workload capabilities. The QNAP JBOD Manager (Available from Q3 2021) allows Windows users to manage and monitor the TL-R1620Sdc, while advanced users can connect using the RJ45 Console Port and use the command line interface (CLI).
