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.
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.
PCIe expansion for upgrading 10GbE transmission or enabling GPGPU computing
The TS-h686 features two PCIe Gen 3 x8 slots (each slot provides up to 64 Gb/s bandwidth) and supports installing expansion cards to enable additional functions and greater application potential.
