• Dual 2.5GbE connectivity

  High-speed 2.5GbE accelerates intensive file access, large backup/restoration tasks, virtualization, and multimedia transfer.

• SSD caching and AI acceleration

  Two M.2 NVMe PCIe Gen 3 slots allow implementing SSD cache acceleration, SSD storage pool, or a for faster image recognition.

• Flexible PCIe expansion

  Three PCIe slots allow for installing 5/10/25GbE adapters, Fibre Channel cards, or QM2 cards to increase application performance.

• Virtual machines and containers

  Host virtual machines and containerized apps on one device to optimize resource utilization and IT budgeting. Supports SR-IOV.

• Hybrid cloud

  Realize hybrid cloud applications by working with the cache space reserved on NAS to ensure low-latency cloud data access.

• Storage scalability

  Satisfy ever-growing storage needs by connecting flexible and economical QNAP expansion enclosures.
