AMD Embedded R-Series SoC built for speed
AMD Embedded R-Series SoC uses "Excavator" x86 CPU cores, and supports AMD Radeon™ 3rd-generation GCN and DDR4. The AMD RX-421BD APU, featuring an integrated Radeon™ R7 series Graphics Processing Unit, provides the TVS-473e with the high-end model of the AMD R-Series family. The TVS-473e also provides two PCIe Gen3 x4 expansion slots for boosting the potential for 10GbE network performance.
AMD R-Series quad-core APU, up to 64GB RAM
Equipped with a next-gen AMD R-Series RX-421BD quad-core 2.1 GHz APU (Turbo Core up to 3.4 GHz) with up to 64GB dual channel DDR4 RAM, the TVS-473e enables lightning-fast multi-tasking with low power consumption for up to 1106 MB/s throughput with a 10GbE configuration. With a hardware-accelerated encryption engine with AES-NI, the TVS-473e also provides unmatched encryption performance in its class (up to 1091 MB/s with AES 256-bit full NAS volume encryption) to boost system performance, security, and ensuring the safety of sensitive business data stored in the NAS.
Expands NAS potential with dual PCIe slots
The TVS-473e features a pair of PCIe (Gen3 x4) slots, allowing for installing optional single/dual-port 10GbE NICs to accelerate applications that demand higher bandwidth such as virtualization, media workflows, and backup/restoration tasks for an ever-growing amount of data; or a USB 3.1 Gen2 (10Gb/s) expansion card for transferring large media files to and from USB storage. You can also insert QM2 cards or wireless network cards to extend NAS functionality.
Greater efficiency with SSD caching and 10GbE connectivity
The TVS-473e supports the innovative QM2 PCIe card that allows for adding up to two M.2 SSDs. You can configure SSD caching, or create a RAID 5 tiered storage along with the two M.2 SSDs in the NAS*. As these M.2 SSDs will not occupy any 3.5-inch drive bays, the QM2 card allows you to maximize both your storage capacity and performance. There are also QM2 cards that include 10GbE 10GBASE-T connectivity to provide SSD caching with high-speed network connectivity on a single card.
SSD cache with Qtier™ optimization for around-the-clock acceleration
The TVS-473e features SSD caching, and also supports optional M.2 SATA 6Gb/s SSDs. Using an SSD cache boosts overall system performance, and is perfect for improving the overall workflow of random IOPS demanding applications such as virtualization. QNAP’s Qtier™ Technology empowers the TVS-473e with auto tiering that further helps continuously optimize storage efficiency across M.2 SSD, 2.5-inch SSD, and high-capacity SATA drives with around-the-clock acceleration. The new Qtier™ 2.0 features IO-awareness that empowers SSD-tiered storage with a cache-like reserved space to handle burst I/O in real time, greatly maximizing the advantages of SSD.
Easy installation and direct access to files with USB QuickAccess
With its innovative USB QuickAccess port, the TVS-473e eliminates the complications of first-time NAS installation and provides direct access to files stored on the TVS-473e - all without needing network connectivity. Simply use a compatible cable* to connect the TVS-473e to a PC or Mac device, and use Qfinder Pro** to configure it. It is just that easy. You can also assign access rights to users for different folders to prevent unauthorized access to important files.
Superior 4K video transcoding and dual 4K HDMI output
The TVS-473e features AMD 3rd Gen GCN architecture with breakthrough GPU performance to support 4K H.264 video decoding and stunning 4K UHD display. It delivers superior real-time 4K and 1080p video transcoding to convert videos to universal formats that can be smoothly played on PCs, mobile devices and Smart TVs. The TVS-473e offers dual HDMI output that support "duplicated" or "extended" desktop configurations. You can connect the NAS to a HDTV or A/V receiver and use the media player in HybridDesk Station (HD Station) with the QNAP remote control (sold separately) or Qremote mobile app to enjoy rich media content and 4K @30Hz videos with the best audiovisual experience.
Block-based iSCSI LUN: Ideal choice for virtualization storage
The TVS-473e supports block-based iSCSI LUN, and supports VMware®, Citrix®, Microsoft® Hyper-V® and Windows Server® 2012 R2, providing high-performance, reliable and affordable storage solution for virtualization environments. The TVS-473e supports VMware VAAI and Microsoft ODX to increase performance by offloading server loading for ESXi server and Hyper-V respectively, and supports QNAP vSphere Client plug-in and QNAP SMI-S provider with enhanced operational efficiency and management in virtualization applications. Moreover, using the iSCSI Extensions for RDMA (iSER) protocol with a compatible 10GbE NIC helps boost data transfer performance of the TVS-473e as VMware® ESXi storage, providing an essential tool to optimize demanding virtualization applications.
