QNAP ES1686DC-R2-2123IT-64G - Network Attached Storage, Black, Grey

The QNAP ES1686DC-R2-2123IT-64G is a 3U rackmount enterprise NAS for centralized data management and high-availability storage. It features 16 hot-swap drive bays that accommodate 2.5-inch and 3.5-inch drives via a Serial Attached SCSI (SAS) interface. An Intel Xeon D-2123IT quad-core processor runs at a base frequency of 2.2 GHz, boosting to 3.0 GHz. The system runs the QNAP QES operating system, which is based on the ZFS file system to support data integrity. The standard configuration includes 64 GB of ECC DDR4 memory to detect and correct single-bit memory faults. It is optimized for enterprise environments that require reliable shared storage and backup.

Networking options include three RJ45 Ethernet ports and four SFP+ fiber ports. The redundant power supply ensures the system remains operational if a single unit fails, providing 700 W with a typical power consumption of 500.87 W. For storage resilience, the unit supports RAID levels 0, 1, 5, 6, 10, 50, and 60. Two 60 mm fans provide active cooling. Expansion is provided through two PCIe Gen 3 x8 slots, which allow for additional interface cards. Administrators can manage data using protocols including iSCSI, Fibre Channel, and NFS. Two USB 3.2 Gen 1 Type-A ports are located on the chassis for external devices.

• Eight DDR4 memory slots supporting up to 512 GB of RAM for high-density virtualization.
• Dual PCIe Gen 3 x8 slots for network interface cards or SAS expansion adapters.
• Access Control List (ACL) support for granular permission management.
• Hot spare support for automatic RAID array rebuilding after disk failure.
• 4 GB of built-in flash memory for the operating system and system configuration.
• Online RAID migration for changing RAID levels without system downtime.
• Multi-lingual support for management interface localization.
