Flexible storage scalability for Turbo NAS. Simple & reliable. The QNAP REXP-1200U-RP expansion enclosure is designed for expanding the storage space on the Turbo NAS & can support maximum 384TB 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, & TV broadcast storage. Contains the WD Red HDD’s with WD’s NASware technology for enhanced efficiency, reliability & compatibility Highlights: Plug & use, seamless capacity expansion Missing mode protection High density, high efficiency & high scalability Flexibly manage storage with the QTS Storage Manger Supports SAS/SATA 6 Gbps hard drives & SSD Backup storage for the Turbo NAS Plug & use, seamless capacity expansion Simply connect a REXP-1200U-RP to a Turbo NAS* & power it on. The Turbo NAS will detect the hard drives in the REXP-1200U-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 & high scalability The REXP-1200U-RP supports 12 hard drives & 48TB raw capacity in 2U rack space. The REXP-1200U-RP has two SAS wide ports (IN port & OUT port) for host connectivity & 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 24 Gbps per host connection. Powerful QTS Storage Manager The QTS Storage Manager neatly presents tools & options for managing system storage with an intuitive graphical interface, which simplifies the process of NAS capacity expansion & REXP-1200U-RP management. IT administrators can easily monitor the health status of REXP-1200U-RP & disks in it. When cascading multiple expansion enclosures in a rack, the Locate Disk & 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 administrator can use the REXP-1200U-RP as a budget-friendly external storage to perform speedy & secure backup tasks for the Turbo NAS. The QNAP RTRR (Real-Time Remote Replication) or rsync service lets IT administrator back up the Turbo NAS data to the REXP-1200U-RP on a real time or scheduled basis. Flexible drive type & capacity The REXP-1200U-RP offers high flexibility in hard drive selection. IT administrators can choose enterprise-level SAS hard drives with high performance & high reliability for mission critical application, low-cost but high-capacity SATA hard drives for large data archiving, or high-speed & high stability SSD for I/O intensive operations. Just make the best use of each drive.
