Original Press Release:

QNAP TL SAS 12Gb/s JBOD Series for Windows Server Expansion, Supports Multipath Routing, SAS Zoning, and Daisy Chaining

Taipei, Taiwan, February 1, 2021 - QNAP® Systems, announced the TL SAS storage enclosures, including the 12-bay TL-R1220Sep-RP and 16-bay TL-R1620Sep-RP models, which support storage expansion for Windows® servers. The TL SAS JBOD supports SAS 12Gbps transmission, delivering up to 96Gbps transfer speed and supporting Broadcom® SAS DataBolt bandwidth optimization and multipath routing (Multipath I/O, MPIO). Users can daisy-chain multiple JBODs to expand capacity or divide one JBOD into multiple zones, providing a key solution for massive storage with high-performance, high-capacity, and high storage utilization.

The TL SAS JBOD is powered by a SAS35x28R / SAS35x36R SAS Expander with four SAS wide ports each combining four 12Gbps SAS lanes. By configuring two wide ports with link aggregation, transfer speeds can reach 96Gb/s. Featuring Broadcom® SAS DataBolt™ bandwidth optimization technology, the TL SAS JBOD features an intelligent data buffer for transferring data to drives at speeds that match the performance of the host server, allowing users to benefit from high-speed 12Gb/s SAS transmission with existing 6Gb/s infrastructure. If the host Windows® server supports multipath routing (Multipath I/O, MPIO), high availability can be achieved. If one route fails, another transmission route can be used to access the data and ensure continuous system operations. The TL SAS JBOD also supports SAS zoning technology, allowing one JBOD to serve as storage expansion for up to four Windows servers.

“The TL SAS JBOD is a key storage expansion solution for both QNAP NAS and Windows Server. TL SAS JBODs are easy to set up and can be managed with either the QNAP JBOD Manager utility or command line without requiring an Internet connection,” said Sam Lin, Product Manager of QNAP.

Featuring a short-depth design, the TL SAS JBOD is suitable for universal deployment. Up to sixteen expansion enclosures can be daisy-chained via high-speed mini SAS HD cables to support massive storage capacity applications.

Supported host servers

Windows Server 2012 R2/ 2016/ 2019

Note: The Windows® server requires a compatible Broadcom® SAS HBA PCIe expansion card.
