2. Product Overview
This chapter provides basic information about the QNAP ES1686dc NAS.
About the ES1686dc
The ES1686dc is designed to deliver a scalable platform for enterprise-level solutions. It is equipped with a
powerful multi-core processor, AES-NI hardware encryption engine, and both USB 3.0 and 10GbE ports,
allowing it to deliver optimal performance for enterprise users. The ES1686dc supports up to 16 storage
drives. This number can be increased by attaching multiple expansion units. It has M.2 drive support and
redundant storage controllers and power supplies to provide the necessary reliability, serviceability, and read/
write speeds.

The device performs a basic system reset. All default
system settings are also restored, deleting all previously
created users, user groups, and shared folders. The user
data stored on the disks is retained.
To retrieve data after an advanced system reset, recreate
the previous folder structure on the NAS.
Battery Backup Unit
The battery backup unit (BBU) protects the data integrity of each storage controller. If both power supply
units fail during a power outage, the system uses the BBUs for power and activates the asynchronous
DRAM refresh (ADR) feature of the processors. While the BBUs supply power, cached data stored in the
DRAM are written to the M.2 SSDs. This process is called Copy-to-Flash. Once power is restored and the
system restarts, any logs, archives, or other important data are reconstructed from the data stored on the M.
2 SSDs.
Product Overview 17
Warning
During a power outage, do not remove storage controllers while their BBU status LEDs are
orange. Removing a storage controller during this period interrupts the Copy-to-Flash
process and may result in data loss.

Drive Installation
The ES1686dc is compatible with 3.5-inch and 2.5-inch hard drives, and 2.5-inch and M.2 solid state drives.
Drive Configuration
The ES1686dc supports the following drive configurations.
Configuration Description
All SSDs Use all solid-state drives (SSDs) for I/O intensive workloads and business-
critical storage.
All HDDs Use all hard disk drives (HDDs) for the best value for capacity. This
configuration is suitable for storing cold data and running applications that
require sequential data access, such as video editing and surveillance software.
Hybrid Use a combination of SSDs and HDDs to balance cost and performance. In
addition to high input/output operations per second (IOPS), the ES1686dc also
supports creating an SSD read cache to further increase storage performance.
This configuration is especially suitable for virtual desktop infrastructure (VDI)
and web servers.
When using a hybrid configuration, QNAP recommends installing SSDs in drive
bays 1 to 4.
Drive bays 1 to 4 are reserved for system configurations. QNAP recommends using drive bays 5 to 16 for
data storage. This setup prevents data storage operations from interfering with the basic operation of the
NAS system. This also allows easier migration of drives used for data storage.
For details on drive numbering, see Drive Numbering.

Replacing Memory Modules
Each storage controller has eight memory slots. You can increase the memory capacity of the NAS by
upgrading the memory module.
Use only QNAP modules of the same type and capacity to maintain system performance and stability. You
can purchase QNAP memory modules from authorized resellers.
Important
For best results, QNAP recommends installing modules in pairs.
• Ensure that each pair uses identical modules.
• Install the pairs in sequence and follow the assigned slots for each pair.
• The ES1686dc has eight memory slots. For optimal quad-channel performance, install
memory modules on either four or eight of the slots. When installing four memory
modules, install the memory in slots 1, 3, 6, and 8.
For details on slot numbering, see System Board.
Module Pair Slot Number
First pair Slots 1 and 8
Second pair Slots 3 and 6
Third pair Slots 2 and 7

Management Port Configuration
Management is provided by the Intel® i210 Gigabit Ethernet controller. The management port allows you to
connect to the QES desktop of the ES1686dc. The default ES1686dc management website is
169.254.100.100:8080. If the NAS has been configured to use DHCP, you can use the QNAP Qfinder Pro to
check the IP address of the NAS. Make sure the NAS and the computer that runs the QNAP Qfinder Pro are
connected to the same subnet.
The system requires that the management IP addresses are configured on both controllers and that the
controllers’ management ports are connected to the management network. This should be a separate LAN
or a VLAN because you should not use the production LAN or VLAN for management network traffic. To
configure the management port IP address, refer to the QES User Guide. If one storage controller fails, you
can enable takeover function from the High Availability app in QES to manage the system through the
management port of the other storage controller with the same IP address. For more information, see the
QES User Guide.
The following diagrams illustrate management port connections.

Multipath I/O Network Configuration
Multipath I/O (MPIO) is a fault-tolerance technique where more than one physical network path is created
between a server and a storage device such as a NAS. If any one network path goes down due to the failure
of a switch, cable, or network card, the server can route I/O through the remaining network paths with no
storage downtime. The ES1686dc supports MPIO on iSCSI connections using standard Ethernet
infrastructure.
The following diagram is an example of how the multipath I/O should be implemented:
Important
Requirements:
• Each QES data port must use a static IP address.
Installation and Configuration 53
ES1686dc User Guide
• Each server and storage controller must be connected to at least two different physical
switches on different subnets.
Recommendations:
• Use dedicated network switches or VLANs to separate iSCSI traffic from other network
traffic.
