Run additional operating systems on the TS-451+
The Virtualization Station transforms the TS-451+ into a 2-in-a-box NAS that can function as an all-in-one NAS and a virtualization platform that supports multiple operating systems, fast VM creation, VM backup & restoration, VM import/export, snapshot, Device Management for centrally managing VM, and enables desktop operations on web browsers. With the easy-to-use interface, you can centrally manage all of the VMs created on the TS-451+ with minimal effort. You can also download VMs on demand from online VM markets and import them to the TS-451+ without any complex procedures.
Container Station – LXC and Docker® Containers inclusive
QNAP Container Station exclusively integrates LXC and Docker® lightweight virtualization technologies, allowing you to operate multiple isolated Linux® systems on the TS-451+ as well as download apps from the built-in Docker Hub® Registry. It supports container import/export and permission settings, and features an informative dashboard and flexible user interface for you to manage multiple containers. You can experience the amazing Container Station and enjoy the playground of virtual containers with the TS-451+. Container Station also supports Online Document app, which allows you to directly view, edit and store files of various types anytime on your NAS, including Office documents, images and text files.
Real-time & offline video transcoding*
The TS-451+ delivers superior real-time video transcoding (up to 4K H.264) to convert your videos to formats that can be smoothly played on PCs, mobile devices and Smart TVs. It allows for multiple devices to simultaneously view different videos stored on the TS-451+ with on-the-fly hardware accelerated transcoding, saving your time in converting videos to different formats for different devices.
With the benefits of offline transcoding, if you can only connect to an Internet connection with limited/restricted bandwidth, you can still enjoy smooth videos via File Station, Video Station, or the Qfile app by selecting a pre-rendered lower-resolution video, saving system resources of the TS-451+ for other applications. The TS-451+ also allows you to set a dedicated folder for automatic video transcoding.
Enjoy media freely with multi-zone multimedia control
Use your TS-451+ as a multi-zone multimedia system to fill every corner of your house with your choice of media. You can centrally manage and stream photos, music and videos from the TS-451+ to different rooms from a single device using Bluetooth®& USB devices connected to the TS-451+ (for music streaming only), HDMI, DLNA®, Apple TV® and Chromecast™*. Every room member in different zones can enjoy the convenience and simplicity for media playback and multimedia storage.
Alternatively, to enjoy multimedia yourself, you can choose DLNA-compatible devices, use the Qfile app on an iOS® device to browse videos/photos and play on the TV via Apple TV®, or transform the TS-451+ into a powerful streaming machine with DLNA®, Roku®, Amazon® Fire TV, and Google TV™ support with the support of Plex Media Server.
