The ES1640dc is whole-new 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, the ES1640dc delivers “real business-class” cloud computing data storage. The ES1640dc features the brand-new QES operating system that allows almost 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. The ES1640dc provides the same user experience as the current QNAP NAS and QTS system, allowing business users to enjoy the easy learning curve and quickly deploy the system, and making it ideal for small and medium businesses with budget constraints or large-scale IT divisions coping with mission-critical tasks.
