Product description

General Features

Small Footprint, Big Opportunities
• Compared to a traditional 4-bay rackmount NAS, the TS-431XeU has a depth of only 11.46". This makes the TS-431XeU a solid 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.

1.7 GHz Quad-Core CPU and 10GbE SFP+ Port
• The TS-431XeU is equipped with a 1.7 GHz Annapurna Labs Alpine AL314 Quad-Core ARM Cortex-A15 processor, SATA III 6 Gb/s connectivity, and 8GB of 1600 MHz DDR3 RAM. Its encryption acceleration engine provides AES 256-bit full NAS volume encryption, boosting system performance & security while also ensuring the safety of sensitive business data. 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.

SSD Cache Acceleration
• The TS-431XeU supports SSD caching to boost the IOPS performance of storage volumes to increase operational efficiency. It is good for improving the overall workflow of IOPS-demanding applications and allows the best of both cost and performance by combining SSDs with HDDs.

Reduce the Impact of Ransomware or System Failures 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 help ensure the safety of your files and data.

High Reliability Design Helps Ensure 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 strong 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 - Intelligent NAS Operating System
