QNAP ES1686DC-2142IT-48G – Enterprise ZFS NAS with Dual Controllers

Overview

The QNAP ES1686DC-2142IT-48G is an Enterprise ZFS NAS featuring a dual active-active controller architecture, designed to provide near-zero downtime for mission-critical operations. By utilizing two Intel Xeon D-2142IT 8-core processors, the system ensures that if one controller fails, the other takes over immediately to maintain data availability. It is specifically built for high-demand environments like VDI, massive file servers, and virtualization.

Running on the ZFS-based QES operating system, this Enterprise ZFS NAS focuses on data integrity and storage efficiency. It supports block-level data deduplication, inline compression, and virtually unlimited snapshots. With 48GB of ECC memory (expandable up to 512GB per controller), the system provides the computational overhead required to manage complex RAID configurations and heavy I/O throughput across its 16 SAS 12Gb/s drive bays.

This unit is ideal for 3U rack deployment in enterprise data centers requiring high-performance iSCSI or NFS storage. It seamlessly integrates with VMware, Windows Server, and Citrix environments. Due to its active-active design, it requires SAS drives for dual-path connectivity; utilizing SATA drives requires specific QNAP QDA-series adapters to maintain high-availability protocols.

Key Features

• Dual active-active controllers ensure continuous service and redundancy.

• Intel Xeon D-2142IT 8-core CPU delivers high-performance ZFS operations.

• 48GB DDR4 ECC RAM prevents data corruption and supports deduplication.

• Four 10GbE SFP+ ports per controller accelerate intensive data transfer.

• Battery-protected DRAM write cache prevents data loss during power failure.
