QNAP Systems, Inc.today 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 12 Gbps transmission, delivering up to 96 Gbps 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 12 Gbps SAS lanes. By configuring two wide ports with link aggregation, transfer speeds can reach 96 Gb/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 12 Gb/s SAS transmission with existing 6 Gb/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.
