Integrating an application server and storage server into one system, the next-generation TDS-16489U R2 also provides you with the option of using either QES (an enterprise-grade OS that provides efficient and reliable storage for mission-critical tasks) or QTS (a feature-rich OS for storage and diverse application servers). Whether being used as a file server, virtualization server, VDI, medium-sized data center, video streaming, surveillance storage, and efficient file backup & recovery, the flexible TDS-16489U R2 with dual CPU and dual OS options is your ideal solution.

Install PCIe cards to increase application performance, including 40GbE/ 25GbE/ 10GbE adapters, Fibre Channel cards, and graphics cards.

QES ensures data integrity with self-healing and uses end-to-end checksums to detect and correct silent data corruption.

QES supports data deduplication and compression to optimize storage utilization and data access performance.

QES supports near-limitless snapshots and SnapSync for efficient remote backup & disaster recovery solution.

Reliable storage for virtualization. QTS supports hosting VMs and containers; QES supports block-level storage for OpenStack® environments.

QTS supports software-defined SSD over-provisioning to improve write performance for IOPS-demanding applications.

Multiplied computing power with dual Intel® Xeon® E5 processors

Built for data-intensive applications and demanding workloads, the TDS-16489U R2 is powered by dual Intel® Xeon® E5-2600 v4 multi-core processors, up to 1 TB quad-channel DDR4 2133MHz RDIMM/LRDIMM RAM (Long-DIMM x16), and 12Gb/s SAS drive support to deliver outstanding performance for data transmission and applications. While providing the power to handle CPU-demanding tasks and everyday application needs such as virtualization, video surveillance, and media streaming, the TDS-16489U R2's unrivaled performance provides the ability for businesses to improve their Big Data computing to explore greater business opportunities.

Extraordinary hardware design. Immense, reliable & innovative

Convertible NAS that supports two operating systems

The TDS-16489U R2 provides flexibility to choose from two operating systems, enabling businesses to deploy an operating system that fits their needs and goals in different stages.

	QES QNAP Enterprise System	QTS QNAP NAS System
OS Kernel	FreeBSD	Linux
File system	ZFS	Ext4
CIFS/FTP/NFS/iSCSI
Snapshot upper limit	65535	1024
Remote disaster backup and recovery	SnapSync	Snapshot Replica
Deduplication		Deduplicate backup data at the source (Hybrid Backup Sync 3.0)
Real-time data compression
End-to-end data integrity
Qtier (Auto Tiering)
Application services (Virtualization Station, Web Server, multimedia service, etc.)
App Center
Application scenarios	• Reliable storage for mission-critical business tasks. • The perfect backup storage for the dual-controller Enterprise ZFS NAS.	• High-performance storage with SSD and Qtier technology for maximized cost-efficiency. • Storage for hosting virtual machines and containerized applications. • Application server using QTS services (Web server, VPN server, FTP server, etc).

Note:
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

Enable lightning-fast throughout for bandwidth-demanding tasks such as virtualization, massive data transmission, and fast backup/restoration. Empower the NAS with iSER support by installing Mellanox® SmartNICs.

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.

QTS supports comprehensive virtualization for utmost IT efficiency
