QNAP CTL-ES1686DC-2123IT-32G – Enterprise ZFS NAS with Dual Controllers
Overview :
The QNAP CTL-ES1686DC-2123IT-32G is an Enterprise ZFS NAS engineered for mission-critical storage environments that demand absolute uptime. It utilizes a dual active-active controller architecture, allowing both controllers to provide services simultaneously. This design ensures that if one controller fails, the secondary controller takes over the full workload with near-zero service interruption, making it a reliable choice for enterprise virtualization and high-availability file sharing.
Equipped with two Intel Xeon D-2123IT 4-core processors and 32GB of DDR4 ECC RDIMM memory (16GB per controller), this Enterprise ZFS NAS is optimized for the QES operating system. QES leverages the ZFS file system to offer advanced data reduction capabilities, such as inline data deduplication and compression. These features significantly improve storage efficiency and performance in VDI environments where redundant data is prevalent.
This unit is designed for 3U rackmount deployment and features 16 SAS 12Gb/s drive bays for high-throughput disk access. It integrates seamlessly with major virtualization platforms like VMware, Microsoft Hyper-V, and Citrix. To maintain the high-availability dual-path hardware architecture, SAS drives are required; if SATA drives are used, they must be paired with QNAP QDA-series adapters to ensure both controllers can communicate with the storage media.
