Description
QNAP REXP-1220U-RP 12 Bay Rackmount 12Gbps SAS RAID Expansion Enclosure
Simple & flexible storage expansion for QNAP NAS
The REXP-1220U-RP expansion enclosure is designed for expanding the storage space on a QNAP NAS* by connecting multiple expansion enclosures via high-speed mini SAS cables. Featuring a 12 Gbps SAS interface on the chassis, the REXP-1220U-RP ensures fast data passthrough from 12 Gbps SAS-enabled QNAP NAS even when using 6Gbps hard drives. This is especially useful for large data applications that require high performance interconnection, such as video surveillance, archiving large data, and TV broadcast storage.
- Plug and use, seamless capacity expansion
- Missing mode protection
- High density, high efficiency and high scalability
- Flexible management with the QTS Storage Manager
- Backup storage for the QNAP NAS
- Supports SAS 12 Gbps, SAS/SATA 6 Gbps HDD and SSD
- Backward compatible with a 6 Gbps SAS-enabled NAS / REXP expansion unit and 6 Gbps SAS HBA by using the 12Gb/s SAS for 6Gb/s SAS cable (CAB-SAS10M-8644-8088).
*Supported QNAP NAS models and the maximum number of applicable expansion enclosures.
