Key Features. Dual active controllers NVRAM cache dual mini-SAS channel backup 40GbE-ready SAS 12Gb/s-enabledQES operating system which is based on FreeBSD and ZFSData deduplication and compression allows hosting over 500 VDI in one chassisNear-limitless snapshots and SnapSync for efficient disaster recoveryNAS and iSCSI/IP-SAN storage supporting VMware® Microsoft® Hyper-V KVM and advanced virtualization featuresFully supports OpenStack® iSCSI Cinder driverScalable design up to 1 PB total storage capacity5 year warranty - Global warranty inclusive. E5 dual-controller for nearly zero downtime high-availability. The ES1640dc is powered by two 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 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 a great 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 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 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. QES operating system combining ZFS file system. The ES1640dc features the QES (QNAP Enterprise Storage) operating system which is based on the simple and efficient FreeBSD kernel and the ZFS file system that has been proven through years of experience to be suitable for high-end enterprise applications. QES supports dual active controller architecture and remote disaster recovery can be directly integrated into OpenStack cloud
environments and is designed for intensive virtualization and VDI applications with optimal performance. Continuing the same user experience with the QTS operating system QES provides business users with an easy learning curve to quickly deploy the ES1640dc and provides a great storage solution jointly with the current QNAP NAS. ZFS - the file system for business data storage. The ES1640dc features ZFS a combined file system and logical volume manager to support various advanced functions for high-end enterprise storage including powerful storage expansion flexible storage pools simplified management high-performance SSD cache nearly limitless snapshots and cloning data deduplication in-line compression and thin provisioning with reclaim for optimized utilization for virtual machine
storage. ZFS is designed with a focus on data integrity and uses its end-to-end checksums to detect and correct silent data corruption caused by hardware defects bugs in firmware or metadata errors effectively protecting user's data. Strong disaster recovery made by nearly limitless snapshots and SnapSync. The ES1640dc supports up to 65535 snapshots for iSCSI LUN and shared folders. When executing a remote snapshot backup it only needs to transfer changed data and can use deduplication and compression to significantly reduce the amount of transferred data. The ES1640dc can provide remote backup SnapSync fo
