The TL-R1220Sep-RP is a 2U rackmount JBOD enclosure that adds 12 SAS/SATA drive bays to a QNAP NAS over 12Gb/s SAS. It is not a standalone NAS: it has no CPU, network ports or operating system, and needs a host with SAS ports or a QXP PCIe SAS card. Its main draw is scale. Up to 16 enclosures can be daisy-chained for roughly 3.4PB of raw capacity, and four SFF-8644 wide ports give up to 192Gbps to a single host. Broadcom DataBolt combines two 6Gb/s links into one 12Gb/s stream, so older 6Gb/s backplanes and drives still get more throughput. Multipath routing on a supporting QTS or QuTS hero NAS keeps traffic flowing if one path drops. It suits surveillance, backup and media archives that outgrow a NAS chassis, not home users.

The QNAP TL-R1220Sep-RP is a 12-bay, 2U rackmount SAS 12Gb/s JBOD expansion enclosure. It adds storage space to a NAS running QTS or QuTS hero. Up to sixteen enclosures can be daisy-chained with mini SAS HD cables, for up to 3.4PB of raw capacity.
It uses Broadcom SAS DataBolt bandwidth optimization to combine two 6Gb/s connections into one 12Gb/s data stream, so existing 6Gb/s infrastructure runs faster. Four mini SAS HD SFF-8644 Wide Ports deliver up to 192Gbps transfer speed when connected to a single host. With a NAS that supports multipath routing, data transmission is smoother and the system can keep running continuously.
The enclosure's storage space and settings are managed with Storage & Snapshot Manager on the host NAS. It can also transfer large files from one device to another, which conserves network bandwidth and performance. Its short-depth design suits a wide range of rack deployments.
