QNAP TS-831XU-RP 8-bay rackmount NAS with dual 10GbE SFP+ ports and redundant power supplies, for centralised storage and backup.
The QNAP TS-831XU-RP, also catalogued as TS831XU-RP, is an eight-bay rackmount NAS that runs QNAP's QTS operating system. It takes SATA hard drives and SATA SSDs and builds them into RAID 0, 1, 5, 6 or 10 arrays. A quad-core processor serves that storage over two 10GbE SFP+ ports. Redundant power supplies keep the unit running if one supply or one power feed fails, which matters in a rack where the NAS holds shared data or backups. IT teams in Doha and across Qatar buy a refurbished TS-831XU-RP as a central file server, as a backup target for servers and workstations, or as a shared repository for a department that has outgrown a desktop NAS. The SFP+ ports suit sites that already run a 10GbE core switch and want storage that can keep pace with it.
NAS-QNAP-TS831XU-RPFull configuration
The TS-831XU-RP is a complete appliance: processor, network and power are built in, and capacity is set by the drives fitted in the eight bays. The 10GbE ports are SFP+ cages rather than RJ45, so each link needs a transceiver or a direct attach cable.
What this configuration suits
Compare the workload you have in mind against the fitted components.
Departmental and small business file sharing, where several users open and save documents, drawings or media on one central share.
RAID 6 across eight hard drives gives large usable capacity and survives two drive failures, which suits backup data held for weeks or months.
A faster tier built from SATA SSDs in RAID 10, for small shared datasets that many users read at once over the 10GbE links.
Heavy databases, large virtualisation clusters or workloads that need NVMe or SAS drives belong on a different platform. The SFP+ ports only deliver their full speed when the switch and clients on the other side also run 10GbE.
Compatibility
The unit works with standard SATA drives and standard SFP+ network hardware. The items below are what buyers most often add before putting it into service.
| Item | Compatible type |
|---|---|
| Hard drives | SATA HDD |
| Solid state drives | SATA SSD |
| 10GbE links | SFP+ transceivers or SFP+ direct attach cables |
| RAID layouts | RAID 0, 1, 5, 6, 10 |
Use drives of the same capacity within one RAID group, because the array sizes every member to the smallest drive. NAS-rated or enterprise SATA drives cope better with continuous operation than desktop drives. For SFP+ links, match the transceiver type to the cabling already in the rack: short-range optics for fibre, or a direct attach copper cable for a switch in the same or adjacent rack. Connect each power supply to a separate feed or UPS so the redundancy protects against a feed failure as well as a supply failure.

Why buy refurbished
Enterprise hardware, tested in Doha, at a fraction of the price of new
Every unit we sell has already proven itself in a data centre. We test it again, grade it, and back it with a warranty before it leaves our stock.
Tested before it ships
POST, burn-in, memory and power-supply checks on every unit. Anything that fails is repaired or pulled from stock, not sold.
Same performance, lower cost
A Xeon runs the same workloads whether it is new or two years old. Spend the difference on more CPUs, memory or storage.
In stock, not on order
New enterprise hardware can take weeks or months to arrive. Ours is on the shelf in Doha and delivered across Qatar within a day.
Warranty and local support
Every unit is covered. Installation, configuration and hardware support are handled by our own team in Qatar, not a call centre abroad.
