Intel® Xeon® D desktop QuTS hero NAS with four 2.5GbE ports, designed for real-time SnapSync data backup and virtual machine applications Delivering enterprise performance at SMB prices, the TS-h686 features an Intel® Xeon® D processor and DDR4 ECC (Error Correcting Code) memory (expandable to 128 GB) with dependable reliability. With the ZFS-based QuTS hero operating system, the TS-h686 ensures data integrity and supports block-level inline data deduplication and compression, near-limitless snapshots, and real-time SnapSync. The TS-h686 helps your business achieve reliable service-level agreement performance in various use cases, including mission-critical file servers, virtualization servers, collaborative video editing, or efficient data backup and recovery applications. Four 2.5GbE ports accelerate file sharing across teams and devices, virtual machine applications or multimedia transmission. DDR4 ECC memory detects and corrects single-bit memory errors, demonstrating high reliability for crucial applications. Two M.2 NVMe Gen 3 x4 SSD slots (each slot providing up to 3.2 GB/s bandwidth) enable SSD caching to boost random read/write performance. Two PCIe slots allow for 5GbE/10GbE/25GbE/40GbE adapters, QM2 cards, or entry-level graphics cards to increase application performance. Scalable storage supporting virtual machines, containerized apps, centralized storage, backup, sharing, and disaster recovery. QuTS hero combines ZFS advantages with the QTS App Center ecosystem to empower your business. Powerful Intel® Xeon® D processor with up to 128 GB DDR4 ECC memory The TS-h686 uses an Intel® Xeon® D-1600 series processor and DDR4 ECC memory that can detect and correct single-bit memory errors as they occur to prevent downtime and data loss. Supporting up to 128 GB RAM to cope with higher workloads, the TS-h686 provides a high-performance and reliable NAS solution for demanding business IT environments. Set SSD caching to boost IOPS with M.2 NVMe SSD While SSD prices continue to fall, and SSD capacity and performance continue to increase, organizations can easily take advantage of SSD strengths. The TS-h686 comes with two 2.5-inch SSD drive bays and two M.2 NVMe Gen3 x4 SSD slots that allow you to flexibly configure SSD caching to increase IOPS performance and reduce storage volume latency. This is especially perfect for databases and virtual machine applications. Without occupying any 3.5-inch drive bays, the TS-h686 allows you to maximize both your storage capacity and performance. Quad-port 2.5GbE meets today's high-bandwidth demands Featuring four native 2.5GbE RJ45 LAN ports (backwards compatible with 1G/100M), the TS-h686 allows you to use existing CAT5e cables to upgrade network speeds from 1 Gigabit to 2.5 Gigabit. The support of Port Trunking and failover further satisfies bandwidth and reliability demanding applications including virtualization, large file transfers, high-speed backup/restoration, and any real-time application. QNAP also offers numerous options of managed and unmanaged 10GbE/2.5GbE switches, assisting organizations in implementing high-speed, secure and scalable network environments without going over budget.
