QM2 expansion card redeﬁnes NAS function
QNAP's QM2 is a PCIe expansion card that features dual M.2 SSD slots and 10GbE connectivity* (individual cards may vary in functionality). This allows users to easily set up SSD caching to optimize NAS performance. 10GbE-compatible models can also future proof the TS-831XU-RP for use with 10GbE networks. Equipped with a dedicated cooling module, the QM2 can maintain its high performance even when tasked with the highest workloads.
*Selected models with 10GbE connectivity is backward compatible with 5GbE/2.5GbE/1GbE/100MbE network.
SSD cache acceleration
The TS-831XU-RP supports SSD caching to greatly boost the IOPS performance of storage volumes to increase operational efficiency. It is perfect for improving the overall workflow of IOPS-demanding applications and allows the best of both cost and performance by combining SSDs with HDDs.
Fast Disaster Recovery with Snapshots
The TS-831XU-RP supports block-based Snapshots, which can record and save the state of the file system and the metadata of the files outside the file system at any time. In the event of an unexpected NAS failure or if struck by a ransomware attack, the snapshots remain intact, allowing you to quickly and easily restore the system back to a previous normal state. You can preserve and restore multiple versions of the same file, folder or even the entire volume. The TS-831XU-RP supports up to 64 snapshots per volume or LUN (up to 256 in total). Snapshot Replica facilitates double protection that replicates snapshots to a remote QNAP NAS or server.
Note: The Snapshots feature will be available from QTS 4.3.4.
High reliability design ensuring business continuity
The business-ready TS-831XU-RP is designed to provide 24/7 operations and services. The support for comprehensive RAID configurations and hot-swapping allow for replacing hard drives without service interruption. QNAP's advanced RAID recovery technology also helps if any healthy drives are accidentally removed from a degraded RAID volume. The system can be recovered by reinserting the wrongly-removed hard drives so the data can still be accessible. The TS-831XU-RP delivers high reliability and efficiency with support for multiple port-trunking modes including fail-over support. The TS-831XU-RP also features a hot-swappable redundant power supply to ensure maximum system uptime.
VJBOD: use NAS to expand other NAS capacity for maximizing sharing economy
Besides using expansion enclosures, there is an additional option to expand NAS storage capacity. QNAP VJBOD (Virtual JBOD) is network-based JBOD, allowing you to expand the storage of a QNAP NAS with multiple QNAP NAS units. The TS-831XU-RP offers great potential for economically expanding the storage of other QNAP NAS with VJBOD, and to create virtual storage pools and volumes on virtual disks for operating NAS services.
1. ARM-based NAS currently does not support VJBOD "Host" function to utilize other NAS storage space.
2. The remote QNAP NAS must support iSCSI and Storage Pools and use QTS 4.2.1 (or newer).
Rapidly deploy IoT apps with Container Station
QNAP Container Station exclusively integrates LXC and Docker® lightweight virtualization technologies, allowing you to operate multiple isolated Linux® systems on the TS-831XU-RP as well as download apps from the built-in Docker Hub® Registry. It supports container import/export and permission settings, and features an informative dashboard and flexible user interface for you to manage multiple containers. What's more, Container Station provides an ideal platform with countless hands-on containerized apps for developers to easily apply, rapidly develop, and conveniently deploy IoT applications. Simply search "IoT" in Container Station, acquire proper containers, and design your own IoT stack with "QIoT Containers" for diverse IoT applications.
QTS 4.3 – The most intelligent and intuitive NAS operating system
QTS 4.3 provides more intelligent features to enhance management efficiency, including Qfiling that helps categorize files and performs based on schedules to make organizing files automatic and efficient, and much more. With its intuitive and simplified user interface, QTS features an intelligent desktop allows you to find desired functions quickly, create desktop shortcuts or group shortcuts, monitor important system information on a real-time basis, and open multiple application windows to run multiple tasks concurrently, bringing greater working efficiency. QTS breaks the barriers of devices, platforms, and geography to bring optimized cloud experiences and incorporates advanced features.
Cross-platform file sharing, centralized data storage
The TS-831XU-RP supports SMB/CIFS, NFS, and AFP protocols for file sharing across Windows®, Mac®, Linux®/UNIX® networks.

The TS-831XU-RP provides numerous security options, such as encrypted access, IP blocking, 2-step verification, and more. IT administrators can also control the access rights of each user to different folders, preventing unauthorized access to important files. The TS-831XU-RP supports AES 256-bit encryption, preventing sensitive business data from unauthorized access and breach even if the hard drives or the entire system were stolen.
Secure access with VPN Server & VPN Client
With the new QVPN app which integrates settings for VPN server and VPN client, the TS-831XU-RP can be used as a VPN server with L2TP/IPsec, OpenVPN, and PPTP support, allowing you to securely access data shared within private local networks. It can also be used as a VPN Client to connect to other VPN servers (connecting multiple servers at the same time is possible) or virtual private networks through PPTP and OpenVPN for secure data transmission. You can connect devices to your NAS and the VPN server at home to access data on the LAN; via VPN Client on your NAS, for example, you can connect to VPN servers in foreign countries for accessing regionally-restricted services.
Qsirch - A smarter, faster way to search
The TS-831XU-RP supports Qsirch, a search tool for quick file searching. Qsirch supports thumbnail previews, and even remembers your search history allowing you to quickly navigate to files you've previously searched for. It adds Qsirch Helper (browser extension for Google Chrome™ and Mozilla Firefox®) that allows you to search for files on your NAS when you use Google Search. Qsirch is a huge productivity boost that greatly reduces the time spent looking for files on the NAS, allowing you to focus on other tasks.
