QES - Designed for high-end enterprise IT environments

Suited for enterprise-level storage with maximized business continuity by adopting ZFS that focuses on data integrity.

QES supports deduplication and compression to maximize VDI storage performance

QES supports block-based data deduplication to reclaim storage used by redundant/repeated data and in-line data compression to shrink file sizes. Both functions optimize storage utilization and provide cost savings for businesses when using SSDs (particularly for all-flash storage deployment). In VDI environments where there could be over 90% duplicate data from OS images and applications that are spread over virtual desktops, deduplicated virtual desktops become easier to be cached to achieve optimal virtual desktop performance.


QES streamlines remote backups with nearly limitless snapshots and SnapSync

QES 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 block-level SnapSync. In the event of a primary site failure, the complete and efficient SnapSync assists businesses to resume essential services in the shortest time.

Business Continuity

Copy-on-write technology makes QES snapshot creation almost instantaneous without affecting ongoing data writing. SnapSync supports incremental backups, real-time deduplication and compression. The source TDS-16489U R2 will perform deduplication before compressing the metadata to reduce synchronized data and save bandwidth resources.


VMware SRM

SnapSync supports VMware Site Recovery Manager (SRM) that offers enterprise-class remote backup & disaster recovery solution for virtual applications. With the Storage Replication Adapter (SRA) for SRM, operation overheads of the ESXi® server can be offloaded to the QNAP storage array to accelerate and simplify virtual machine backup and restoration.


Ideal backup NAS for Enterprise ZFS NAS

When running the QES operating system, the TDS-16489U R2 is the perfect backup storage for the dual-controller Enterprise ZFS NAS using SnapSync. If the Enterprise ZFS NAS unexpectedly stops, the TDS-16489U R2 can immediately recover all the backed up data locally to take over operations and services with minimized RTO (Recovery time objectives) and RPO (Recovery Point Objective). It prevents the downtime required to restore data from a remote QTS NAS/rsync server back to the recovered Enterprise ZFS NAS.


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 TDS-16489U R2 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.


QTS - Empowering storage for the high-speed era

Ideal for flexible virtualization deployment, application expandability, and storage optimization with auto-tiered architecture.



QuDedup technology deduplicates data at the source, helping to reduce the time and storage space needed for backup.



Seamlessly connect local storage with cloud object storage to easily backup local application data to the cloud.



Enabling local caching on NAS for low-latency access to the connected cloud services.



Integrated AI algorithm for auto photo organization and a powerful search tool for more intuitive and streamlined photo management.
