The ES1686dc runs the latest QES 2.1.0 operating system that supports near-limitless snapshots, SnapSync, block-level data deduplication, and inline data compression. Whether being used as a mission-critical file server, virtualization server, VDI, medium-sized data center, video streaming, surveillance storage, and efficient file backup & recovery, the ES1686dc helps your business to achieve service-level agreements for performance and uptime.
Features
Active-Active high availability with optimal storage efficiency
In Active-Active storage system architecture, both controllers are able
to provide a complete range of services, which is different from the
Active-Standby architecture of single-controller systems. The
Active-Active architecture does not have the disadvantage of idle
computing resources. To leverage the strengths of the ES1686dc
Active-Active controller architecture, it is recommended to create
multiple storage pools and distribute their ownership between both
controllers. This allows simultaneous output from both controllers for
better load balancing.
With two HA systems you are paying twice the price and causing a load
imbalance as workloads are only processed on the active system. A power
outage could cause data loss, and the disconnected network invalidates
the HA architecture.
Active-Active dual-controller system
Both controllers of the ES1686dc can carry traffic, along with
Copy-To-Flash protection against power failure and the dual-path SAS
interface. Besides conserving computing resources, a high-speed,
uninterrupted, and high-availability storage service is also provided
through communication protocols such as SMB, NFS and iSCSI.
Intel Xeon D dual-controller ensures
high availability and failure-resistant service
Powered by two Intel Xeon D processors, the ES1686dc features a dual
active-active controller architecture that provides failover/failback
operations as the standby controller can quickly take over if one
controller breaks down. Redundant hot-swappable power supplies and
cooling fans are also included to provide businesses with near-zero
downtime high availability. The ES1686dc connects to the JBOD enclosure
(EJ1600 v2) via the dual-path mini-SAS design to sustain continuous
operations even if a JBOD cable is disconnected. Designed around
redundancy, the ES1686dc is the best realization of reliable enterprise
storage for uninterrupted mission-critical enterprise tasks and
productivity.
Multi-level cache technology with both
read and write
The ES1686dc simultaneously supports main memory read cache (L1 ARC),
SSD secondary read cache (L2 ARC), and memory write cache (ZFS Intent
Log) to meet performance demands for various enterprise applications.
Up to 512 GB main memory
Each controller has eight RDIMM slots, allowing for up to 512 GB memory.
M.2 SSD cache
Two M.2 SSD slots (support PCIe Gen3 x4 or SATA 6Gb/s SSDs) provide the
ability to enable SSD caching to increase IOPS performance.
NVRAM cache reduces the risk of losing
write cache data
If unplanned power outages occur, the system can write cache data from
the battery-protected DRAM to M.2 SSD through Copy To Flash (C2F) to
ensure that data is not lost.
PCIe expansion for 40GbE high-speed
networks
The ES1686dc provides two PCIe Gen3 x8 slots connected to the CPU,
allowing you to install lightning-fast 10GbE/40GbE network cards to
boost virtualization, media streaming, and other bandwidth-demanding
applications. Installing Mellanox Smart NICs further adds support for
iSER for improved VMware virtualization performance. You can also
install a QM2 expansion card (QM2-4P-384) to add four additional M.2
2280 PCIe NVMe SSD slots to burst reading performance with SSD caching,
or a SAS expansion card (SAS-12G2E) for connecting up to seven 16-bay
EJ1600 v2 expansion enclosures to seamlessly expand the potential
storage capacity over 1PB, with unprecedented performance of up to
48Gbps per host connection.
Dual controller NAS: High reliability
and high availability
"Reliability" is the priority for mission-critical business
applications. The ES1686dc adopts dual active-active controllers to
provide the most reliable base for business IT storage.
Leverage the 6Gbps SAS to SATA drive
adapter
While SATA 6Gb/s SSDs provide high-performance yet affordable storage,
the lack of dual-port support makes them unsuitable for dual-controller
environments. The QDA-SA adapter is designed for QNAP Enterprise ZFS
NAS, and allows the use of a SATA 6Gb/s drive in a 3.5-inch SAS drive
bay - providing the ability to expand storage capacity by using
cost-effective SATA drives. By installing a SATA drive with the QDA-SA
into the dual-controller ES1686dc, the SATA drive can share these SAS
dual-port advantages to ensure a high-availability, fault-tolerant
enterprise storage environment.
QES 2.1.0: ZFS-based, and optimized
for all flash performance
The ES1686dc features the QES (QNAP Enterprise Storage) 2.1.0 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. Not only does
QES 2.1.0 provide reliable data protection, recovery, and
business-class features, it is optimized for flash storage and is
capable of driving outstanding performance for all-flash storage arrays
to accelerate mission-critical services and eliminate challenges in VDI
environments. QES 2.1.0 also comes with Quality of Service (QoS)
capabilities that help ensure consistent primary storage performance in
multi-application environments. Continuing the same user experience
with the intuitive QTS operating system, QES provides business users
with an easy learning curve for quick implementation within IT
infrastructures.
Unleashed SSD potential -
cost-effective and agile with ultimate performance
QES 2.1.0 features QNAP's exclusive Write Coalescing algorithm that
further optimizes all-flash performance in ZFS, providing a highly
cost-effective all-flash solution for enterprise-class data management
and mission-critical services.
Deduplication and compression to
maximize VDI storage performance
In VDI environments where there could be over 90% duplicate data from
OS images and applications that are spread over virtual desktops, the
QES-powered ES1686dc provides businesses with the most cost-effective
remote virtual desktop platform and mission-critical information
warehousing.
Inline data deduplication
Block-based data deduplication optimizes storage usage and
significantly decreases storage capacity requirements.
Inline compression
Shrinks data size to reduce storage I/O workloads for improved
performance. In VDI, deduplicated virtual desktops are easily cached to
achieve optimal virtual desktop performance.
Inline compaction
Especially helpful for increasing SSD storage utilization efficiency
when highly-repetitive data or massive small files (e.g. transaction
logs of banks or e-commerce) are generated. It delivers higher cost
efficiency of all-flash storage systems.
Self-Healing ensures data integrity
and reliability
Designed with a focus on data integrity, a fundamental aspect of
storage security and reliability, the QES-based ES1686dc uses its
end-to-end checksums to detect and correct silent data corruption
caused by hardware defects, bugs in firmware or metadata errors. If
integrity violations are detected, QES automatically repairs the damage
using data from the other mirror before the data is passed to
applications.
Streamlined remote backups with nearly
limitless snapshots and SnapSync
The ES1686dc supports up to 65,535 snapshots for iSCSI LUN and shared
folders (if 1 snapshot is created every hour, 24 snapshots per day,
then up to 7 years worth of snapshots can be created without needing to
delete any) and replicates snapshots to remote servers by using the
block-level SnapSync. In the event of a primary site failure, SnapSync
assists businesses to resume essential services in the shortest
possible time.
Create VMware/Windows backups for
VSS-Aware applications using QNAP Snapshot Agent
QNAP Netbak Replicator is easy-to-use and VSS-aware backup software,
helping businesses to create complete backups in data centers and
virtualization environments without needing additional 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 ES1686dc and one server for it to be operational.
Compatible with VMware, Microsoft and
Citrix virtualization, and supports iSER
The ES1686dc supports VMware vSphere 6.5, Windows Server 2016, and
Citrix XenServer 7.0 for flexible deployment and management in
virtualization environments. It also supports VMware VAAI and Microsoft
ODX to increase performance by offloading server loading for ESXi
server and Hyper-V respectively. The QNAP vSphere Client plug-in, Web
plug-in and QNAP SMI-S provider are also supported to increase the
efficiency of operations and management in virtualization applications.
The ES1686dc and VMware ESXi server installed with Mellanox Smart NICs
that support iSER can acquire iSER advantages to offload CPU workloads
with boosted VMware virtualization performance.
QES is OpenStack Ready to explore
out-of-the-box enterprise cloud services
QES supports OpenStack Cinder and Manila file sharing services. With
the QNAP Cinder Driver, the ES1686dc can provide 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, providing businesses with a flexible, easy-to-use,
and low-cost storage solution.
