High-performance dual-2.5GbE NAS Powered by a Quad-core AMD Ryzen™ processor, supporting 10GbE or M.2 SSD caching PCIe expandability for virtual applications

With its powerful AMD Ryzen™ V1000 series V1500B Quad-core processor, the TS-873AU-RP is capable of boosting virtual machine performance with up to 4 cores/8 threads at 2.2GHz. The TS-873AU-RP includes two 2.5GbE ports and a PCIe Gen 3 slot, providing you with fast network connectivity and the ability to add extra functionality and additional application potential. The TS-873AU-RP also features a redundant power supply to ensure maximum system uptime. Cutting-edge hardware integrated with comprehensive software solutions makes the TS-873AU-RP the preeminent choice to tackle resource-demanding applications and tasks.

  • Both 2.5GbE ports are backwards compatible with 1GbE/ 100MbE/ 10MbE speeds. Up to 5 Gbps transfer speeds can be achieved by using port trunking.

  • Add extra functionality to the TS-873AU-RP with PCIe cards, including 10GbE ports, SSD caching, extra USB 3.2 Gen 2 ports, wireless networking, or Fibre Channel.

  • Supports entry-level NVIDIA® graphics cards for video processing or GPU-passthrough to VMs.

  • Qtier™ technology and SSD caching enable 24/7 optimized storage efficiency.

  • Host multiple virtual machines and containers to run a wide range of applications on the TS-873AU-RP.

  • Supports block-based and file-based cloud storage gateways with local caching for low-latency access to cloud data.

Absolute performance with AMD Ryzen™ and up to 32GB RAM

Powered by a 4-core/8-thread AMD Ryzen™ V1500B 2.2GHz processor with AES-NI encryption acceleration and up to 32GB DDR4 RAM, the rackmount TS-873AU-RP delivers aggressive yet power-smart performance to drive resource-demanding business applications such as VDI, R&D, private cloud, and server virtualization.

Block-based iSCSI LUN: Ideal choice for virtualization storage

The TS-873AU-RP supports block-based iSCSI LUN and is compatible for VMware®, Citrix®, Microsoft® Hyper-V®, and Windows Server® 2019 virtualization environments to provide a high-performance and affordable storage solution. The TS-873AU-RP also supports VMware VAAI and Microsoft ODX to increase performance by offloading server loading for ESXi server and Hyper-V respectively, and supporting QNAP vSphere Client plug-in with enhanced operational efficiency and management in virtualization applications.

Optimized performance for VMware Virtualization with iSER

The iSCSI Extensions for RDMA (iSER) protocol boosts the data transfer performance of VMware® ESXi storage and reduces the CPU load of the ESXi server. iSER support can be added to the TS-873AU-RP by installing a QNAP QXG-10G2SF-CX4 10GbE PCIe card, which uses the Mellanox® ConnectX-4 controller. iSER can provide a significant increase in performance, providing an essential tool to optimize demanding virtualization applications.

All-in-one server to host virtual machines and containers

Regardless of your virtualization needs, you can count on Virtualization Station and Container Station for complete virtualization support. Use the Network & Virtual Switch app to allocate adequate physical network resources to virtual machines, containers, and the TS-873AU-RP to simplify network deployment.
