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 (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.

Features
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.\

      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 
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.

QES operating system combining ZFS file 
system
The ES1640dc 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, and provides the best 
storage solution jointly with the current QNAP NAS.

ZFS – the best 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 users data.

Deduplication and compression to maximize VDI storage 
performance
There could be over 90% duplicate data from OS images and applications 
that are spread over virtual desktops. The ES1640dc supports block-based data 
deduplication to optimize storage usage from redundant data. Deduplicated 
virtual desktops become easier to be cached to achieve optimal virtual desktop 
performance. In-line data compression helps shrink data size, further optimizing 
storage usage. For mastering storage in a virtualized environment, the ES1640dc 
provides businesses with the most cost-effective remote virtual desktop platform 
and mission-critical information warehousing.

Strong disaster recovery made by nearly limitless snapshots and 
SnapSync
The ES1640dc supports up to 65,536 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 for snapshots at the shortest interval of every five 
minutes, fully supports VMware vCenter Site Recovery (SRM) technology, provides 
Storage Replication Adapter (SRA) for SRM, and provides enterprise-class remote 
backup & disaster recovery solution to fulfill business continuity. 

Well-rounded backup solutions to secure data
 QNAP Netbak Replicator is an easy-to-use and VSS-aware backup 
software, and helps businesses to create complete backups in datacenter and 
virtualization environments without needing to purchase expensive and complex 
commercial software. To build a QNAP Snap Agent and VSS Hardware Provider 
operating environment, all applications (including VSS Service, Requestor, 
Provider and QNAP Snap Agent) can be deployed with VSS-Aware applications on the 
same server, and the minimal requirements are only one ES1640dc and one server 
for it to be operational.

Storage for comprehensive virtualization applications 
The ES1640dc is certified for VMware® vSphere 6.0, and is compatible 
with Microsoft® Hyper-V and KVM, benefiting flexible deployment and management 
in virtualization environments. The ES1640dc supports VMware VAAI and Microsoft 
ODX to increase performance by offloading server loading for ESXi server and 
Hyper-V respectively, and supports QNAP vSphere Client plug-in, Web plug-in and 
QNAP SMI-S provider with enhanced efficiency of operations and management in 
virtualization applications. 

Compatible with HPE Helion for extending horizons to OpenStack 
cloud 
As QNAP’s first "OpenStack Ready" product line, the ES1640dc is not only 
suitable for virtualization and virtual desktop environments but also the best 
choice for cloud applications. QES supports OpenStack® Cinder and iSCSI Cinder 
Node drivers, and provides block-level storage space to virtual machines. It not 
only accelerates the deployment of virtual machines and enhances virtual machine 
image access efficiency through iSCSI, but it is also easier to integrate into 
commercial cloud storage platforms. QES can be easily coupled with HPE Helion* 
to provide simpler and more reliable private enterprise hybrid cloud solutions, 
to ensure that enterprises can still enjoy uninterrupted, highly available, 
highly-stable services in dense virtualized environments.
5 year warranty - Global warranty inclusive QNAP's ES1640dc offers 5 
year warranty with 3-year global warranty inclusive at no extra cost. This 
premier warranty demonstrates QNAP’s attention to the essential business needs 
of continuous operations and non-interrupted services to their 
customers.
