| Supported NAS System | DataBolt Bandwidth Optimization | Multipath Routing |
| Expand the storage space of a QTS/QuTS hero NAS, supports up to 3.4PB raw capacity by daisy-chaining up to 16 expansion enclosures. | Combine multiple 6Gb/s transmissions into 12 Gb/s data streams to achieve faster speed with existing 6Gb/s infrastructure. | Ensure smooth data transmission and continuous operation by using the TL-R1220Sep-RP with a NAS that supports multipath routing. |
| Storage Management | Remote Files Transfer | Easy Installation & Storage |
| Manage the storage space and settings of the TL-R1220Sep-RP with Storage & Snapshot Manager on the host NAS. | Conserve network bandwidth and performance by using the TL-R1220Sep-RP to transfer huge files from one device to another. | With a short-depth design, the TL-R1220Sep-RP is suitable for universal deployment. |
Note: The QNAP NAS requires QTS 4.5.1 / QuTS hero h4.5.1 (or later) with a PCIe SAS storage expansion card installed. Check PCIe SAS card compatibility
The TL-R1220Sep-RP is powered by a low-power 28nm SAS35x28R SAS Expander and supports 12/6 Gb/s SAS/SATA drives. Also, it has four 12 Gb/s SAS 3.0 (x4 Lane) SFF-8644 SAS Wide Ports. By connecting the TL-R1220Sep-RP to the host NAS and daisy-chaining multiple JBODs with two wide ports configured with link aggregation, the solution delivers up to 96Gb/s transfer speed.

Featuring Broadcom® SAS DataBolt™ bandwidth optimization technology, the TL-R1220Sep-RP features an intelligent data buffer for transferring data to drives at speeds that match the performance of the host NAS. Whether the TL-R1220Sep-RP uses 12Gb/s or 6Gb/s drives, the NAS host will transfer data to the TL-R1220Sep-RP at 12Gb/s, allowing you benefit from high-speed 12Gb/s SAS transmission with existing 6Gb/s infrastructure.
Note: The QNAP host NAS requires QTS 4.5.1 / QuTS hero h4.5.1 (or later) with a PCIe SAS storage expansion card installed. Check PCIe SAS card compatibility

The TL-R1220Sep-RP has four 12 Gb/s SAS 3.0 (x4 Lane) SFF-8644 SAS Wide Ports. Up to sixteen TL-R1220Sep-RP can be daisy-chained to achieve a raw capacity of up to 3.4PB.
Note:
1. Use the CAB-SAS10M-8644-8088 12Gb/s to 6Gb/s external cable to connect to SAS NAS / REXP expansion enclosures and 6 Gb/s SAS HBA.
2. The host NAS requires one QXP-1620S-B3616W SAS card to daisy chain sixteen JBODs with single path routing. Using multipath routing with link aggregation enabled, the host NAS with one QXP-1620S-B3616W SAS card can daisy chain four JBODs; the host NAS with two QXP-1620S-B3616W SAS cards can daisy chain eight JBODs.
By daisy chaining the TL-R1220Sep-RP, data transmission loads can be balanced with multipath routing to achieve high availability. If one route fails, another transmission route can be used to access the data and ensure continuous system operations. The TL-R1220Sep-RP also features a redundant power supply to ensure system uptime.
Note: Multipath routing requires a host NAS with QTS 4.5.1 / QuTS hero h4.5.1 (or later).
By daisy-chaining your NAS to multiple TL SAS JBODs and REXP SAS JBODs, you can take advantage of multipath routing and link aggregation to benefit from higher transfer speeds and system availability.

With Storage & Snapshot Manager on the host NAS, you can configure and manage the TL-R1220Sep-RP settings (including RAID groups, storage pools and snapshots), allowing you to easily expand NAS storage to accommodate massive data or backup files. You can also configure and manage the TL-R1220Sep-RP via the Console Port.
Moving many small files or a single large data file over a network can be time-consuming and negatively impact network performance. By setting up the RAID configuration on the TL-R1220Sep-RP, you can use it to move files to another computer or NAS. Simply save the files to the TL-R1220Sep-RP, connect it to the destination device, and then copy the files over.
Note: When using software RAID configuration, the TL-R1220Sep-RP migration only supports hosts that use the same operating system.
