QNAP ES1686dc-2123IT-64G SAN/NAS Storage System

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

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.

• Intel® Xeon® D dual active-active controllers provide supreme uptime and redundancy to ensure high availability.

• Battery-protected DRAM write to cache data protection and Flash read acceleration provides industry-leading random access performance.

• Two M.2 SSD slots allow for implementing SSD cache acceleration.

• Four 10GbE SFP+ ports accelerate virtualization, large file sharing, and intensive data transfer.

• Near-limitless snapshots and SnapSync for snapshot remote backup assist businesses to resume essential services in the shortest time.

• Supports VMware® vSphere® 6.5, Windows Server® 2016 and Citrix® XenServer® 7.0 for storage virtualization. Compatible with OpenStack® cloud environments.

Active-Active high availability with optimal storage efficiency

In Active-Active storage system architecture, both controllers are able to provide a complete range of services, which is different from the Active-Standby architecture of single-controller systems. The Active-Active architecture does not have the disadvantage of idle computing resources. To leverage the strengths of the ES1686dc Active-Active controller architecture, it is recommended to create multiple storage pools and distribute their ownership between both controllers. This allows simultaneous output from both controllers for better load balancing.

Active-Standby single-controller system

With two HA systems you are paying twice the price and causing a load imbalance as workloads are only processed on the active system. A power outage could cause data loss, and the disconnected network invalidates the HA architecture.

Active-Active dual-controller system

Both controllers of the ES1686dc can carry traffic, along with Copy-To-Flash protection against power failure and the dual-path SAS interface. Besides conserving computing resources, a high-speed, uninterrupted, and high-availability storage service is also provided through communication protocols such as SMB, NFS and iSCSI.

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.
