Product Overview QNAP furthers its innovation into the field of business servers and introduces the TDS-16489U, a powerful Double Server that integrates an application server and storage server into one chassis. The TDS-16489U is powered by dual Intel® Xeon® E5 processors with RAM expandable to 1TB and with a server-grade hardware design that optimizes mission-critical tasks and boasts unrivaled performance for Big Data computing. Coupled with Auto Tiering support, 12Gb/s SAS drives and 40GbE expandability, the TDS-16489U performs as an efficient, scalable and unrivaled unified and tiered storage solution for businesses to fulfill cross-platform file sharing, backups, iSCSI & virtualization applications, and everyday practical business needs.

Business-Ready Double Server – Fulfilling Computing and Storage in One Box
When it comes to virtualization deployment, it usually requires high-performance application servers and high-capacity storage servers to build suitable environments. 10GbE or 40GbE networks are necessary to connect virtualization environments to storage via iSCSI or NFS protocols. QNAP’s powerful TDS-16489U combines all of these features into one box as an all-around Double Server. You can run multiple guest OS such as Windows® and Linux® with Virtualization Station, containerized apps with Container Station, and directly store all the data on the TDS-16489U through the internal 12Gb/s SAS interface, saving more money and space as a one-device solution with exceptional application performance and lower TCO of storage.

A Big Data Solution Powered by Dual Intel® Xeon® E5 CPUs
Distinguishably powered by dual Intel® Xeon® E5-2600 v3 processors (with 4-core, 6-core and 8-core configurations), up to 1TB DDR4 2133MHz RDIMM/LRDIMM RAM (16 DIMM), and 12Gb/s SAS drive support the TDS-16489U can deliver outstanding performance for data transmission and applications. While providing the power to handle CPU-demanding tasks and everyday application needs, the TDS-16489U's unrivaled performance provides the ability for businesses and organizations to improve their Big Data computing to gain further insights, opportunities and values.

Server-Grade Hardware Design. Robust, Reliable & Innovative.
Suited for enterprise environments which demand the highest performance, simplified IT management, uninterrupted service, and optimized virtualization environments, the TDS-16489U is designed with high-standard hardware specifications to meet those needs.

Dual Processors for Big Data Computing
The TDS-16489U features dual Intel® Xeon® E5-2600 v3 processors to drive performance-demanding Big Data computing capabilities for complex, high-demanding workloads.

16 RDIMM/LRDIMM, up to 1TB
With 16 memory slots, up to 1TB DDR4 RDIMM can be installed in the TDS-16489U.

64 GB (8GB x 8 = 64GB RDIMM)
128 GB (16GB x 8 = 128GB RDIMM)
256 GB (32GB x 8 = 256GB RDIMM)
512 GB (64GB x 8 = 512GB RDIMM)
1 TB (64GB x 16 = 1TB RDIMM)

Independent SAS 12Gb/s Controller Increases I/O Performance
Instead of using a SAS controller with expanders to utilize the full capacity of supported drives on a single controller, the TDS-16489U adopts multiple SAS controllers to streamline the architecture with improved connectivity and performance. The TDS-16489U has three LSI 12Gb/s SAS controllers, with each controller supporting 7 ports of 12Gpbs SAS, for connectivity with up to 16 HDDs and 4 SSDs, ensuring each controller can fully utilize the maximum bandwidth to optimize performance and reliability.

Graphic Card Support for Virtualization
PCIe Gen.3 x 16 slot supports AMD Radeon™ R7 and R9 Series Graphics Cards for GPU passthrough to virtualization applications. The IOMMU allows the attached AMD GPU to be given to specific virtual machines to power the image and motion processing from the guest OS when running multiple virtual machines for graphic applications.

10 / 40GbE Card Support
The TDS-16489U is a 40GbE-expandable solution for maximizing performance via iSCSI or NFS protocols to tackle potential bottlenecks for dramatically-changing and loaded virtualization computing environments.

PCIe SSD NVMe for Cache Acceleration
NVMe (Non-Volatile Memory Express) is an advanced interface/protocol developed for SSDs attached through the PCIe bus. The TDS-16489U supports PCIe SSD NVMe to provide up to 10 times faster IOPS performance and to decrease I/O latency 3 times, improving the overall workflow of random IOPS demanding applications.

12Gb/s SAS HBA Support
A 12Gb/s SAS HBA can be inserted to provide two 12Gb/s mini SAS interfaces for connecting 12Gb/s SAS-enabled expansion enclosures (REXP-1620U-RP and REXP-1220U-RP) for future-proof scalable storage deployment.

4 x 2.5” SSD for Caching
The TDS-16489U features an extra four 2.5” disk trays at the rear to provide SSD caching without taking space from hard drives. By installing high-performance SSDs, the IOPS performance of storage volumes can be remarkably boosted, making it ideal for random IOPS demanding applications such as databases and virtualization.

IPMI Helps Ease Server Management
IPMI (Intelligent Platform Management Interface) supports intelligent system monitoring, controlling, and hardware logs for TDS-16489U platform status such as system temperatures, voltages and fans. IPMI operates independently from the QTS operating system to allow administrators to remotely manage the TDS-16489U even when the system is powered down. IPMI provides a web-based management interface, supports power-down and rebooting from remote control and hardware monitoring and logs.

Built-in 4 x 10GbE SFP+ Ports
10GbE networks greatly benefit virtualization applications, data backup/restoration and massive data transmission. The TDS-16489U features four 10GbE SFP+ ports which can optimize system performance and assist businesses to flexibly build virtualization environments and increase productivity.

Build a 40GbE-Ready Solution for Computing and Storage
The TDS-16489U supports Mellanox® ConnectX-3 Pro adapter cards with 10/40/56 Gigabit Ethernet connectivity to deliver the most cost-effective computing and storage Ethernet Interconnection solution. It helps achieve significantly higher throughput for high-performance embedded I/O applications and virtualization acceleration. Businesses can greatly benefit from the fast, flexible storage network of the 40GbE-ready TDS-16489U for boosting their mission-critical IT performance.

Enable Auto Tiering with Qtier Technology
QNAP’s Qtier Technology empowers the TDS-16489U with Auto Tiering that helps continuously optimize storage efficiency. With Auto Tiering, the TDS-16489U can automatically move hot data to high-performance storage tiers and cold data to lower-cost, higher-capacity drives, making the TDS-16489U an extremely efficient shared resource. Businesses will no longer have to invest heavily in expensive Flash technology, but can still enjoy exceptional application performance and lower TCO of storage from Auto Tiering with the TDS-16489U.
