REXP-1000 Pro - Features - QNAP

The QNAP REXP-1000 Pro expansion enclosure is designed for expanding the storage space on the Turbo NAS and can support maximum 240TB 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

*The TS-EC880 Pro and TS-EC1080 Pro are shipped with 2GB RAM which supports a maximum of two REXP-1000 Pro expansion enclosures. Upgrading to 4GB RAM allows them to support up to four REXP-1000 Pro.
**The maximum capacity is calculated by 8TB HDDs.

Note: A 12 Gb/s SAS expansion card (P/N: SAS-12G2E) is required if the NAS does not have Mini-SAS ports. An external Mini-SAS HD SFF-8644 to Mini-SAS SFF-8088 Cable (P/N: CAB-SAS10M-8644-8088) is required for use with the SAS 12 Gb/s port and the transfer rate over the cable will be 6 Gb/s.

Plug and use, seamless capacity expansion

Simply connect a REXP-1000 Pro to a Turbo NAS* and power it on. The Turbo NAS will detect the hard drives in the REXP-1000 Pro as newly installed local drives. The Turbo NAS capacity can be expanded seamlessly by using the powerful QTS Storage Manager.

* Optional purchase of SAS expansion card and QTS 4.1.0 (or newer) are required for the Turbo NAS.

Missing mode protection

When disconnection of the expansion enclosures occurs, the Turbo NAS enters missing mode automatically and blocks I/O access to protect the stored data. The system can then recover from the missing mode to the normal state with data staying intact when the disconnection is resolved.

High density, high efficiency and highly scalable

The REXP-1000 Pro supports 10 hard drives and 60TB raw capacity, and 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-1000 Pro management. IT administrators can easily monitor the health status of REXP-1000 Pro 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-1000 Pro 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-1000 Pro on a real time or scheduled basis.

Flexible drive selection

The REXP-1000 Pro 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.
