Qnap TS-431XeU 4-Bay Short Depth Rackmount NAS (TS-431XeU-2G)

 The high-performance quad-core short depth TS-431XeU includes a 10GbE SFP+ port to fully support 10GbE high-speed networks at a budget price with maximized ROI. The short depth design is perfectly suitable for installing the TS-431XeU in a compact rack, or places with a lot of cabling. The TS-431XeU provides versatile all-in-one functionality and unique features including VJBOD (Virtual JBOD) - an economical way to utilize unused NAS storage space for expanding the storage capacity of other QNAP NAS - and Container Station - that allows users to rapidly develop and deploy Internet of Things (IoT) apps. The TS-431XeU is a cost-effective storage solution designed for growing businesses looking for backup, restoration, private cloud, storage for virtualization, and to future-proof their IT infrastructure for 10GbE networks.

Smaller Footprint for Bigger Opportunities
Compared to a traditional 4-bay rackmount NAS, the TS-431XeU has a depth of only 11.46 inches (291 mm). This makes the TS-431XeU an excellent choice for smaller racks, and the unused space can be reserved for cabling or ventilation. The TS-431XeU is space-saving for flexible deployment and is especially suitable for multiple locations and applications including offices, audiovisual rooms and security surveillance recording.

Quad-core CPU and built-in one 10GbE SFP+ port
The TS-431XeU is equipped with an Annapurna Labs, an Amazon company, Alpine AL314 quad-core 1.7 GHz ARM® Cortex-A15 processor with SATA 6Gb/s and up to 8GB DDR3 RAM. Its encryption acceleration engine provides unmatched encryption performance in its class with AES 256-bit full NAS volume encryption, boosting system performance & security while ensuring the safety of sensitive business data stored in the TS-431XeU. Besides two Gigabit Ethernet ports, the TS-431XeU also includes a 10GbE SFP+ port to fully support 10GbE high-speed networks for businesses that demand higher bandwidth for virtualization and fast backup & restoration of an ever-growing amount of data.

Reduce the impact of ransomware or system failure with Snapshots
The TS-431XeU supports snapshots, which can record the system status and data at any single moment*. If the system unexpectedly fails or is infected with ransomware, you can instantly restore files from a snapshot. The intuitive snapshot tool in the QTS Storage Manager can be used to take snapshots of your data, and restore data from snapshots if necessary. Always take regular snapshots to ensure the safety of your files and data.

High reliability design ensuring business continuity
The business-ready TS-431XeU 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-431XeU delivers high reliability and efficiency with support for multiple port-trunking modes including fail-over support.

VJBOD: Maximize storage utilization across multiple QNAP NAS
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-431XeU 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.

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-431XeU as well as download apps from the built-in Docker Hub® Registry for unlimited containerized applications. What's better, Container Station supports the QIoT Containers platform that helps quickly structure your IoT environment and deployment on your private IoT cloud, boosting microservices and modernizing legacy applications to drive more business opportunities.

QTS - The intelligent NAS operating system
With multiple applications and functions, QTS enhances management efficiency, personal productivity, entertainment, and much more. The user-friendly QTS features an intelligent desktop that allows you to find desired functions quickly, monitor important system information on a real-time basis, open multiple application windows to run multiple tasks concurrently with greater working efficiency, and provides a built-in App Center with install-on-demand apps to extend NAS functionality. Empowered by intelligent agent services that simplify system operations and management, QTS breaks down barriers of devices, platforms, and geography to provide you with the optimum cloud experience.

Optimized collaboration with cross-platform file sharing and sync
The TS-431XeU centrally stores data, logs and various files, and supports SMB/CIFS, NFS, and AFP protocols for file sharing across Windows®, Mac®, Linux®/UNIX® networks. Coupled with Qsync - a utility that turns a QNAP NAS into a safe, high-capacity data center for file synchronization - any file uploaded to the TS-431XeU will be made available for all linked devices, such as computers, laptops or mobile devices. You can sync shared folders and team folders for group file sharing, greatly enhancing the flexibility of team projects and collaboration.

Well-rounded backup & disaster recovery solutions
The TS-431XeU offers flexible backup solutions for Windows® and Mac® users. It also supports Hybrid Backup Sync that consolidates backup, restoration and synchronization functions (using RTRR, rsync, FTP, CIFS/SMB) for easily transferring data to local, remote and cloud storage spaces as a comprehensive data storage and disaster recovery plan. Supported cloud services include Amazon® Glacier, Azure™ Storage, Google Cloud Storage™, Google Drive™, Microsoft® OneDrive® for Business, Dropbox®, Amazon® Drive, Yandex® Disk, Box®, hubiC® and Amazon® S3/OpenStack Swift/WebDAV compatible services.

Comprehensive security to protect your data
In open network environments, business data may be exposed in a potential hack. The TS-431XeU provides numerous security options, such as antivirus, 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-431XeU 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. Windows AD server, LDAP server, and built-in LDAP service are also supported.

Secure access with VPN Server & VPN Client
With the new QVPN app which integrates settings for VPN server and VPN client, the TS-431XeU 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-431XeU supports Qsirch, a proprietary search engine for quickly finding files. In addition to previewing files with thumbnails, content abstract and keyword hints, Qsirch even remembers your search history allowing you to quickly navigate to files you've previously searched for. The Qsirch Helper extension (for Google Chrome™ and Mozilla Firefox®) can also be used to search for files on your NAS when using Google Search™. Qsirch provides a huge productivity boost by greatly reducing the time spent looking for files on the NAS.

QmailAgent: A mailroom center for your private cloud
QmailAgent is an online email client that helps you manage multiple email accounts, allowing you to access all of your emails and to easily switch between different accounts. It provides complete functionality for composing, reading and organizing emails. You can even attach files, photos and documents directly from the TS-431XeU when composing emails. iOS® and Android™ users can use the QmailClient app to quickly check multiple email accounts with mobile devices, and to browse & send emails using the QmailAgent on their TS-431XeU.

Comprehensive surveillance solution providing 24/7 security
