Product information

Description

The QNAP ES1686dc R2 is a 3U enterprise NAS rack designed for high-availability storage and continuous business operations. It features dual active-active controllers, redundant power supplies, and the QES operating system based on FreeBSD and ZFS to provide data integrity, failover capability, and petabyte-scale expansion using external enclosures. The system is powered by Intel® Xeon® D processors, supports up to 16 HDD/SSD drives, and offers PCIe Gen3 expansion and dual-channel SAS connectivity for uninterrupted service and growth.

Advantages

Redundant controllers and power supplies minimize downtime by allowing component replacement without service interruption. The QES OS with ZFS provides end-to-end checksums and self-healing to detect and repair silent data corruption. Dual active-active controllers enable automatic failover/failback. PCIe Gen3 slots and dual-channel SAS expansion provide scalable performance and capacity. Features such as Write Coalescing, inline deduplication and compression optimize all-flash performance and maximize storage efficiency for VDI and other deduplication-friendly workloads. Real-time SnapSync and copy-on-write snapshots reduce recovery point objectives and support continuous business operations.

Suitable for

Enterprise virtualization storage for VMware, Hyper-V and Citrix environments
Mission-critical file services and centralized storage
VDI infrastructures requiring high deduplication and performance
Real-time disaster recovery and synchronous replication

Key specifications

Form factor: 3U rackmount chassis
Operating system: QES (ZFS-based, FreeBSD kernel)
Processors: Dual Intel® Xeon® D series (model specified by configuration)
Memory: 48 GB DDR4 (installed in this configuration)
Drive bays supported: Up to 16 HDD/SSD (SAS/SATA compatible)
Expansion: Two PCIe Gen3 x8 slots per controller
Storage expansion: Dual-channel SAS expansion enclosure support for petabyte-scale capacity
High-availability features: Dual active-active controllers, redundant power supplies
Data protection: ZFS end-to-end checksums, self-healing, snapshots, inline deduplication and compression
Network: Ethernet with jumbo frame and iSCSI/iSER support; Fibre Channel expansion card compatible
Cooling: Active cooling
Power supply: Redundant 700 W (total/configuration dependent)

How to use

Install the ES1686dc R2 in a standard 19-inch rack and connect power and management/network interfaces. Populate the drive bays with compatible HDDs or SSDs as required and configure RAID or ZFS storage pools using the QES management interface. Use the provided PCIe slots to add expansion cards (for Fibre Channel or additional connectivity) and connect expansion enclosures via the dual-channel SAS links for increased capacity. Configure controller roles, snapshots, and SnapSync replication in QES to enable high availability and real-time replication between primary and secondary systems.

Usage recommendations

For optimal reliability and performance, use enterprise-grade SAS or SSD drives, enable redundant power supplies and network paths, and configure SnapSync with incremental deduplication and compression enabled. Regularly update QES firmware, monitor system health, and perform snapshot-based backups to minimize data loss and ensure continuous operations.
