Eight-bay rackmount NAS for multi-user environments
The Qnap TS-832PXU-RP-4G-US is a 2U rackmount network-attached storage unit with eight SATA drive bays. It runs on an AnnapurnaLabs Alpine AL324 quad-core ARM Cortex-A57 processor clocked at 1.7GHz with 4GB of installed DDR4 memory. Dual redundant 250W power supplies and connectivity through two 10GbE SFP+ ports plus two 2.5GbE RJ-45 ports are included. The diskless chassis supports up to 176TB of raw capacity.
Suited for teams needing high-throughput file
This platform fits organisations that serve many concurrent users and require redundant power for uptime assurance. The ARM-based architecture and DDR4 memory ceiling of 16GB limit virtualisation density and heavy database workloads. Buyers who need more than eight internal bays or a different processor architecture should consider a different platform.
Maximum raw capacity of 176TB across eight SATA bays
The eight-bay chassis accepts 3.5-inch and 2.5-inch SATA hard drives or SSDs up to a combined 176TB. This ceiling is the decisive figure for capacity planning; any requirement beyond it cannot be met by this unit.

Questions about this item
Does the TS-832PXU-RP-4G-US ship with any drives or must I supply all eight myself?
The unit is a diskless system so you must provide every drive; it accepts up to eight 3.5-inch SATA HDDs, 2.5-inch SATA HDDs or 2.5-inch SATA SSDs.
With one DDR4 DIMM slot and 4 GB already installed, should I add an 8 GB or a 12 GB module to reach the 16 GB limit?
Install a single 12 GB DDR4 DIMM to reach the 16 GB maximum; the board has only one slot so the existing 4 GB module would be replaced.
How do the two 10 GbE SFP+ ports and two 2.5 GbE RJ-45 ports behave under the typical 69.191 W operating load?
Both 10 GbE SFP+ and both 2.5 GbE RJ-45 links remain fully active at line rate while the system draws a typical 69.191 W, thanks to the quad-core 1.7 GHz AL324 processor and redundant 250 W power supplies.
