QNAPES1640DC-V2-E5-96G - 16-Bay Active Dual Controller Intel Xeon E5-2420 V2 32GB DDR3 ECC

The ES1640dc v2 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 v2 delivers "real business-class" cloud computing data storage. The ES1640dc v2 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 v2 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. Intel« Xeon« E5 dual-controller for nearly zero downtime high-availability The ES1640dc v2 is powered by two Intel« Xeon« E5-2400 v2 processors and features dual active-active controller architecture ensuring businesses with nearly zero downtime high availability as the standby controller can quickly take over if one controller breaks down. The ES1640dc v2 connects to the JBOD enclosure (EJ1600 v2) via the dual path mini-SAS design to sustain continuous operations even if an external JBOD cable is disconnected. Designed around redundancy the ES1640dc v2 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 primary priority for mission critical business applications. The ES1640dc v2 adopts dual active-active controllers to provide the most reliable base for business IT storage.

NVRAM cache reducing the risks of losing write cache data To increase random write performance and reliability the ES1640dc v2 features NVRAM modules (DRAM Write Cache with Copy-to-flash) to protect write data. When data is written into NVRAM there are dedicated backup battery units to protect writing to the cache and at the same time the data is replicated to a backup controller to achieve 100% data integrity. NVRAM-backed write cache in the dual-controller architecture presents high performance fault-tolerant and helps reduce flash SSD write amplification.
