Superior Performance, Centralized Storage
with Active-Active Dual Controller

The ES1640dc v2 is an enterprise product line developed by QNAP for mission-critical tasks and intensive virtualization applications. With Intel® Xeon® E5 processors, dual active controllers, ZFS, HPE Helion compatibility and fully supporting virtualization environments, it delivers "real business-class" centralized data storage. The ES1640dc v2 features the new QES operating system that allows near limitless snapshots, block-level data deduplication, and thin provisioning with reclaim, assisting businesses in building the most cost-efficient VDI platform and storage for critical data.

Active-Active Dual Controller

Powered by two Intel® Xeon® E5-2400 v2 processors and features dual active-active controller architecture, ensuring businesses with nearly zero downtime.

Cross-Platform File Sharing

Supports SMB/CIFS and NFS for file sharing across Windows®, Mac®, and Linux®/UNIX® devices.

Virtualization Ready

Certified for VMware® vSphere 6.0, and compatible with Microsoft® Hyper-V and KVM, benefiting flexible deployment and management in virtualization environments.

High Availability

Recover from hardware failures with zero data loss and near-zero downtime. Keep your critical applications and data available at all times.

High Reliability

Designed to run nonstop for 24/7/365 as each unit has gone through exhaustive quality assurance testing to ensure the best reliability and NAS experience.

NLE Compatible

Compatible with popular NLE such as Adobe Premiere, Apple FCP X, Avid Media Composer...and more for 4K video editing.

Powered by ZFS

ZFS is widely considered as one of the most advanced and reliable file system for enterprise storage with a focus on data integrity.

Up To 1000+ TB

By connecting up to seven EJ1600 expansion units via dual-path miniSAS connections, you can expand the total storage capacity to more than 1000+ TB.

5-Year Warranty

ES1640dc v2 comes with 5 year limited warranty with 3-year global warranty inclusive at no extra cost.

High Reliability & High Availability

"Reliability" is the top priority for mission critical business applications. The ES1640dc v2 adopts dual active-active controllers to provide the most reliable base for business IT storage. Featuring dual controllers, dual-loop architecture, the ES1640dc v2 and the corresponding JBOD expansion enclosures (EJ1600) all provide dual-channel (Dual Path) to tolerate single node failure. In the event of a JBOD disconnection, the whole storage system can still run normally. This is essential for better intermachine data protection and capacity scalability. Designed around redundancy, the ES1640dc v2 is the best realization of reliable enterprise storage for uninterrupted mission-critical enterprise tasks and productivity.
