Safety Warnings
1. The ES NAS can operate normally in temperatures of 0ºC–40ºC (32ºF -104ºF) and relative humidity
of 5%–95%. Please make sure the environment is well-ventilated.
2. The power cord and devices connected to the ES NAS must provide correct supply voltage (770W,
100-240 V@50/60Hz).
3. Do not place the ES NAS in direct sunlight or near chemicals. Make sure the temperature
and humidity of the environment are in optimized level.
4. Unplug the power cord and all connected cables before cleaning. Wipe the ES NAS with a dry
towel. Do not use chemical or aerosol to clean the ES NAS.
5. Do not place any objects on the ES NAS for the server’s normal operation and to avoid overheat.
6. Use the flat head screws in the product package to lock the hard disks in the ES NAS when installing
hard disks for proper operation.
7. Do not place the ES NAS near any liquid.
8. Do not place the ES NAS on any uneven surface to avoid falling off and damage.
9. Make sure the voltage is correct in the location where the ES NAS is installed. Contact the
distributor or the local power supply company for the information.
10. Do not place any object on the power cord.
11. Do not attempt to repair the ES NAS in any occasions. Improper disassembly of the product may
expose the users to electric shock or other risks. For any enquiries, please contact the distributor.
12. The ES NAS models should only be installed in the server room and maintained by the
authorized server manager or IT administrator. The server room is locked by key or keycard access
and only certified staff is allowed to enter the server room.
Warning:
Danger of explosion if battery is incorrectly replaced. Replace only with the same or equivalent type
recommended by the manufacturer. Dispose of used batteries according to the manufacturer’s
instructions.
Do NOT touch the fan inside the system to avoid serious injuries.

Chapter 1. Introduction to QNAP ES NAS series
The Enterprise Storage NAS (ES NAS) series offers robust functionality, exceptional reliability,
and availability with the familiar ease of storage management shared by all of QNAP NAS product lines.
The ES NAS series consists of two new major products: the ES1642dc and the ES1640dc. Both of these
models are ideal for mid- to large-scale network storage systems.
The ES NAS chassis adopts the industry standard 19 inch high-density enclosure design. The chassis
supports 16 drives, saving physical space and lowering the energy consumption required for
system cooling in data center environments.
The new ES NAS series has a high availability and serviceability architecture that supports two redundant
Storage Controllers and two power supply units. In addition, the EJ1602 and EJ1600 expansion
enclosures allow for the growth of the storage system up to a 128 drive maximum using the ES NAS’s
SAS drive expansion. These expansion units also have high availability features, including dual power
supplies and redundant cross loop connections to a base ES NAS. The new ES NAS series provides a
number of new capabilities that distinguish them from other enterprise-class NAS. The enhancements
are:
To deliver reliable performance and advanced data services, the ES NAS series combines
enterprise-grade hardware and a storage-optimized, enterprise operating system (QES)
based on ZFS.
The dual storage controllers are powered by Intel® Xeon® E5 series processors that deliver
exceptional computing power to run multiple workloads concurrently in addition to
advanced data services.
The two active storage controllers work as a cluster, backing up one another so that a
single controller can take over the storage resources owned by the other controller in the event
of a controller failure.
Non-disruptive firmware upgrades: Enables controller firmware upgrades with no interruption
to data access.
Cache configurations are available ranging from 1 drive up to 16 drives (full-SSD drive set)
system cache.
Data writes are protected by maintaining a copy in the battery-backed cache unit (comprising
DRAM, an mSATA module, and a battery backup unit) until the data is written to the HDDs.
Storage Pool Striping (across different expansion units) provides a mechanism to aggregates
hard drives into a bigger storage space with the ability to support multiple RAID groups across
different expansion enclosures. (Note that all RAID groups must have the same RAID type.)

10
Storage Pool Striping helps maximize performance by reducing hot spots in arrays and provides
better data safety.
RAID-TP (Triple parity) provides enhanced redundancy and protection in the event of three
simultaneous disk failures.
Triple Mirroring writes data simultaneously to three separate HDDs so if two-thirds of the HDDs
fail in the same RAID group, no data will be lost.
Support for OpenStack enables integration with the OpenStack cloud environment. After the
driver is installed on the OpenStack Cinder nodes, block storage resources can be allocated by
the Cinder nodes.
Data safety and encryption
Combined with the world-class business resiliency and encryption features, the ES NAS series provides a
unique combination of high availability, performance, and security. QES built-in support for
shared folder and LUN encryption ensures critical business-sensitive data is protected. In addition,
WORM (Write Once Read Many) functionality protects data from being tampered at a shared-folder
level.
