The NAS TS-h686 is equipped with an Intel Xeon D processor and DDR4 ECC (Error-Correcting Code) memory, with the ability to expand up to 128 GB for high reliability. Thanks to the QuTS hero operating system based on ZFS, the TS-h686 ensures data integrity and supports deduplication and block-level compression in real-time, virtually unlimited snapshots, and real-time SnapSync. The TS-h686 includes Quality of Service (QoS) settings for various applications and tasks, whether it's a critical file server, virtualization server, VDI, collaborative video editing, or data backup and recovery. Four built-in 2.5 GbE ports enhance data access speeds without significant restructuring of the network infrastructure. Three free PCIe slots allow for the installation of 10, 25, and 40 GbE adapters, QM2 expansion modules, or Fibre Channel interface cards. SSD caching boosts random read and write performance. It supports virtual environments such as VMware, Citrix, Microsoft Hyper-V, and Windows Server 2019, as well as the ability to run virtual machines and containers directly on the NAS. Error-correcting memory ensures high reliability for application performance. QuTS Hero combines the advantages of ZFS with the QTS App Center ecosystem to expand the device's capabilities. High performance with the Intel Xeon D-1600 series processor and DDR4 ECC memory prevents downtime and data loss. The memory can be expanded up to 128 GB to fully leverage the QuTS hero operating system. Fast caching based on M.2 NVMe SSDs. The TS-h686 features two SATA bays for 2.5-inch solid-state drives and two M.2 NVMe Gen3 x4 slots, allowing flexible caching configurations or using SSDs as ultra-fast volumes. This is particularly convenient when working with databases and virtualization.
