QNAP ES1686dc
Next-generation Enterprise ZFS NAS: High-performance and near-zero downtime high availability

 

Overview:

Delivering enterprise high availability, the ES1686dc Enterprise ZFS NAS features Intel® Xeon® D processors, dual active controllers, up to 512 GB DDR4 ECC memory, SAS 12Gb/s, and ZFS that supports logical volume management. The ES1686dc runs the latest QES 2.1.0 operating system that supports near-limitless snapshots, SnapSync, block-level data deduplication, and inline data compression. Whether being used as a mission-critical file server, virtualization server, VDI, medium-sized data center, video streaming, surveillance storage, and efficient file backup & recovery, the ES1686dc helps your business to achieve service-level agreements for performance and uptime.

 

Active-Active high availability with optimal storage efficiency

Intel® Xeon® D dual-controller ensures high availability and failure-resistant service

Powered by two Intel® Xeon® D processors, the ES1686dc features a dual active-active controller architecture that provides failover/failback operations as the standby controller can quickly take over if one controller breaks down. Redundant hot-swappable power supplies and cooling fans are also included to provide businesses with near-zero downtime high availability. The ES1686dc connects to the JBOD enclosure (EJ1600 v2) via the dual-path mini-SAS design to sustain continuous operations even if a JBOD cable is disconnected. Designed around redundancy, the ES1686dc is the best realization of reliable enterprise storage for uninterrupted mission-critical enterprise tasks and productivity.

Dual controller NAS: High reliability and high availability

"Reliability" is the priority for mission-critical business applications. The ES1686dc adopts dual active-active controllers to provide the most reliable base for business IT storage.

QES 2.1.0: ZFS-based, and optimized for all flash performance

The ES1686dc features the QES (QNAP Enterprise Storage) 2.1.0 operating system, which is based on the simple and efficient FreeBSD kernel and the ZFS file system that has been proven through years of experience to be most suitable for high-end enterprise applications. Not only does QES 2.1.0 provide reliable data protection, recovery, and business-class features, it is optimized for flash storage and is capable of driving outstanding performance for all-flash storage arrays to accelerate mission-critical services and eliminate challenges in VDI environments. QES 2.1.0 also comes with Quality of Service (QoS) capabilities that help ensure consistent primary storage performance in multi-application environments. Continuing the same user experience with the intuitive QTS operating system, QES provides business users with an easy learning curve for quick implementation within IT infrastructures.

Self-Healing ensures data integrity and reliability

Designed with a focus on data integrity, a fundamental aspect of storage security and reliability, the QES-based ES1686dc uses its end-to-end checksums to detect and correct silent data corruption caused by hardware defects, bugs in firmware or metadata errors. If integrity violations are detected, QES automatically repairs the damage using data from the other mirror before the data is passed to applications.
