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 (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 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.
1. Dual active-active controller
If one controller fails, the other one will immediately take over to provide high availability with no downtime.
2. Built-in 4 x 10GbE SFP+ ports (ES1640dc v2)
Meets various iSCSI/NFS/CIFS network data transmission requirements.
3. 40GbE NIC support
The PCIe slot supports a dual-port QSFP+ 40GbE NIC to provide massive data transmission potential and to simplify network cabling.
4. SAS 12Gb/s , SATA hard drive and SSD
Dual-controller architecture that supports SAS 12Gb/s , SATA hard drives / SSD, providing versatile storage choices for enterprises.
5-1. NVRAM w/ Copy-to-Flash
Battery-protected DRAM write to cache data protection and Flash read acceleration provides industry-leading random access performance to benefit virtual machine deployment.
5-2. DDR3 RAM
(1) NVRAM dedicated DDR3 memory modules - supports 16/32GB, power required by C2F is supplied by BBU.
(2) Dual-channel DDR3 system main memory - each channel supports 16/32GB, providing up to 32/64GB total capacity.
5-3. mSATA SSD
Stores cache data written by DRAM to ensure information is not lost if the system experiences a sudden power failure.
6. Dual Path Mini-SAS 12Gb/s (EJ1602), 6Gb/s (EJ1600) JBOD architecture
Increases the ES1640dc v2’s potential storage capacity to over 1 PB with expansion enclosures.
7. Intel® Xeon® E5-2400 v2 series processor
Provides the performance required by software-defined storage and commercial mission-critical applications.
8. Field-replaceable unit
Field-replaceable unit (FRU) applies not only to the controllers but also to the cooling fans, power supplies, and the BBU battery pack for C2F (Copy-To-Flash), providing a cost-effective way to maintain complex systems and to replace defective parts.
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.
*To ensure write cache data safety, it is recommended to annually replace the BBU.
QES operating system combining ZFS file system
The ES1640dc v2 features the brand-new 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 most 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 v2, and provides the best storage solution jointly with the current QNAP NAS.

ZFS – the best file system for business data storage
The ES1640dc v2 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.
