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.
- Dual active controllers, NVRAM cache, dual mini-SAS channel backup, 40GbE-ready, SAS 6Gb/s-enabled
- QES operating system which is based on FreeBSD and ZFS
- Data deduplication and compression allows hosting over 200 VDI in one chassis
- Near-limitless snapshots and SnapSync for efficient disaster recovery
- NAS and iSCSI/IP-SAN storage supporting VMware®, Microsoft® Hyper-V, KVM and advanced virtualization features
- Fully supports OpenStack® iSCSI Cinder driver, and compatible with HPE Helion
- Scalable design, up to 1 PB total storage capacity
Intel® Xeon® E5 dual-controller for nearly zero downtime high-availability
The ES1640dc 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 connects to the JBOD enclosure (EJ1620 / EJ1600) via the dual path mini-SAS design to sustain continuous operations even if an external JBOD cable is disconnected. Designed around redundancy, the ES1640dc 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 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 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.
