The compact and feature-rich TS-435XeU provides a professional-grade quad-core NAS solution in short depth rackmount form factor. The native 10GbE SFP+ and 2.5GbE connectivity alongside M.2 NVMe SSD slots that enable cache acceleration allows businesses to efficiently tackle everyday tasks like file backup/restore and to boost team collaboration with higher productivity. The space-efficient short depth design makes the TS-435XeU easy to install in small media cabinets or places with a lot of cabling. Supporting abundant business applications (including file sharing and sync, snapshot protection, containerization, cloud storage gateways, and video streaming), expandable storage capacity, and install-on-demand apps, the TS-435XeU is an ideal cost-effective entry-level rackmount NAS.
• 1 Dual-port 10GbE SFP+ connectivity accelerates intensive file access, large backup/restoration tasks, and media transfer.
• 2 Up to 5 Gbps transfer speeds can be made by setting port trunking with the two built-in 2.5GbE (2.5G/1G/100M) ports.
• 3 Dual M.2 PCIe Gen 3 NVMe SSD slots enable cache acceleration or SSD storage pools for improved performance.
• 4 Host multiple containerized apps to run a wide range of applications and services.
• 5 Build a surveillance system with lower TCO and higher scalability with the subscription-based QVR Elite smart surveillance solution.
• 6 Scale your storage capacity to fit growing data needs by connecting QNAP's expansion units.
Smaller footprint for bigger opportunities
Compared to a traditional 4-bay rackmount NAS, the compact TS-435XeU has a depth of only 11.49 inches (292 mm). This makes the TS-435XeU an excellent choice for smaller racks, and the unused space can be reserved for cabling or ventilation. The TS-435XeU is space-saving for flexible deployment and is especially suitable for multiple locations and applications including offices, audiovisual rooms, and security surveillance recording.
Robust quad-core 2.2 GHz processor
The TS-435XeU is powered by an OCTEON TX2 infrastructure Marvell® CN9130 series CN9131 ARM®v8 Cortex-A72 quad-core 2.2 GHz processor that features integrated workload-optimized hardware accelerators to meet performance, power and total cost of ownership requirements. The TS-435XeU comes with 4 GB DDR4 memory that can be upgraded to 32 GB for enhanced multi-tasking capabilities, and SATA 6 Gb/s support ensures maximum performance from storage drives.
