1. Either QES or QTS can be installed at a time.
2. Switching between operating systems requires reinitializing the disks. Ensure that all data is backed up before switching operating systems.

Abundant I/O capabilities with PCIe expansion

The TDS-16489U R2 features four PCIe slots (3 x PCIe Gen3 x8, 1 x PCIe Gen3 x16) that allow for the usage of various expansion cards to expand application potential.

40GbE/25GbE/10GbE NICs

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.alt

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.alt

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.alt

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.alt

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.alt

QTS - Empowering storage for the high-speed era

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

QTS supports comprehensive virtualization for utmost IT efficiency

Storage for virtualization

The TDS-16489U R2 supports VMware®, Citrix®, Microsoft® Hyper-V® and Windows Server® 2016 virtualization applications. VMware® VAAI and Microsoft® ODX are also supported to increase performance by offloading server loading for ESXi server and Hyper-V respectively, and the QNAP vSphere Client plug-in and QNAP SMI-S provider add enhanced operational efficiency and management in virtualization applications.alt

Application server virtualization

Use Virtualization Station to host multiple virtual machines for various services, for example Microsoft® Exchange Server, Microsoft® SQL Server®, and Active Directory Windows Server®. Big Data tools such as Apache™ Hadoop® and Apache Spark™ can also be easily deployed on the TDS-16489U R2 with Container Station or Virtualization Station.alt

QTS fulfills complete backup planning

The TDS-16489U R2 provides a reliable, flexible backup & disaster recovery solution to assist organizations in routine backup jobs with cost-efficiency and high productivity.

alt Hybrid Backup Sync
Consolidates backup, restoration and synchronization for easily transferring NAS data to local, remote and cloud storage spaces. The new Hybrid Backup Sync 3.0 adds support for data deduplication at the source, multiple version backup, and TCP BBR to improve backup efficiency.
alt Snapshots for Volume & LUN
Snapshots are essential for NAS data protection, and their block-level feature makes them a dependable method for protecting data in the face of the growing threat of ransomware. The TDS-16489U R2 supports up to 256 snapshots per volume/LUN, and up to 1,024 snapshots per NAS.
alt VM backup
With high performance, potentially huge storage capacities, integrated virtualization solutions, and support for snapshots that record the state of the system at any time, the TDS-16489U R2 is perfect for backing up virtual machines.

Attain enterprise-grade SSD performance levels from affordable consumer SSDs

QTS supports software-defined SSD extra over-provisioning (OP) that allows you to allocate additional OP space (from 1% to 60%) to optimize random write speeds and to extend SSD lifespan. Now you can use affordable consumer SSDs for the TDS-16489U R2, adjust the SSD OP, and potentially attain performance and endurance levels similar to enterprise-grade SSDs to enjoy faster file backups, optimized virtualization applications, and smoother multimedia workflows.
