  • Up to 8 expansion enclosures with Max.128 HDDs supported
  • 64TB per expansion enclosure with Max. 512TB raw capacity
  • 24Gbps SAS connection



Flexible storage scalability for Turbo NAS. Simple & reliable.

The QNAP REXP-1600U-RP expansion enclosure is designed for expanding the storage space on the Turbo NAS and can support maximum 512 TB raw capacity* by connecting multiple expansion enclosures via high speed mini SAS cables. This is especially useful for large data applications, such as video surveillance, data archiving, and TV broadcast storage.

*Supported Turbo NAS models and maximum number of applicable expansion enclosures.





Plug and use, seamless capacity expansion

Simply connect a REXP-1600U-RP to a Turbo NAS* and power it on. The Turbo NAS will detect the hard drives in the REXP-1600U-RP as newly installed local drives. The Turbo NAS capacity can be expanded seamlessly by using the powerful QTS Storage Manager.

*QTS 4.0.4 or newer is required for the Turbo NAS.




Missing mode protection

When the disconnection of a RAID expansion enclosure is detected, the Turbo NAS blocks IO access to protect data. The system can recover from the missing mode to the normal state with data staying intact.



High density, high efficiency and high scalability

The REXP-1600U-RP supports 16 hard drives and 64TB raw capacity in 3U rack space. The REXP-1600U-RP has two SAS wide ports (IN port and OUT port) for host connectivity and daisy-chain respectively. Each SAS wide port combines four SAS channels(maximum 8 SAS channels supported per expansion enclosure). The solution delivers unprecedented performance of up to 24Gbps per host connection.




Powerful QTS Storage Manager

The QTS Storage Manager neatly presents tools and options for managing system storage with an intuitive graphical user interface, which simplifies the process of NAS capacity expansion and REXP-1600U-RP management. IT administrators can easily monitor the health status of REXP-1600U-RP and the disks within it. When cascading multiple expansion enclosures in a rack, the Locate Disk and Locate Enclosure functions assist IT administrators for quick maintenance.



An excellent backup solution for the Turbo NAS

In addition to expanding an existing volume, IT administrators can use the REXP-1600U-RP as a budget-friendly external storage to perform speedy and secure backup tasks for the Turbo NAS. The QNAP RTRR (Real-Time Remote Replication) or rsync service lets IT administrators back up the Turbo NAS data to the REXP-1600U-RP on a real time or scheduled basis.




Flexible drive type and capacity

The REXP-1600U-RP offers high flexibility in hard drive selection. IT administrators can choose enterprise-level SAS HDDs with high performance and high reliability for mission critical applications, low-cost but high-capacity SATA HDDs for large data archiving, or high-speed and high stability SSDs for I/O intensive operations.
