General Features

2.1 GHz AMD RX-421ND Quad-Core CPU with AES-NI Encryption Acceleration
• The TS-873U is equipped with a 2.1 GHz AMD RX-421ND Quad-Core processor (turbo core up to 3.4 GHz), dual-channel 8GB DDR4 RAM, four 1GbE ports, and a pre-installed dual-port 10GbE network card. With a dual 10GbE configuration, the TS-873U is capable of delivering up to 1567 MB/s throughput for fast multi-tasking with low power consumption, while the accelerated encryption engine with AES-NI enables encryption performance up to 1315 MB/s with AES 256-bit full NAS volume encryption to boost system performance, security, and help ensure the confidentiality of sensitive business data stored in the NAS.

10GbE Connectivity
• The TS-873U supports 10GbE high-speed networks with an included dual-port 10GbE SFP+ PCIe network adapter, supporting fast data throughput for businesses that demand higher bandwidth for virtualization and fast backup and restoration for growing amounts of data.

Business Continuity
• The business-ready TS-873U is designed to provide 24/7 operations and services. The support for comprehensive RAID configurations and hot-swapping allow for replacing hard drives without service interruption. QNAP's advanced RAID recovery technology also helps if any healthy drives are accidentally removed from a degraded RAID volume. The system can be recovered by reinserting the wrongly-removed hard drives so the data can still be accessible. The TS-873U delivers high reliability and efficiency with quad LAN support for multiple port trunking modes including failover support.

M.2 SATA III 6 Gb/s SSD & 2.5" SSD Cache
• The TS-873U supports SSD caching to increase IOPS performance, and supports higher transfer speeds and reliability with two optional M.2 2280 SATA III 6 Gb/s SSDs. Using an SSD cache boosts overall system performance and is well-suited for improving the overall workflow of random IOPS demanding applications such as virtualization. QNAP's Qtier Technology empowers the TS-873U with Auto Tiering that further helps continuously optimize storage efficiency across M.2 SSDs, 2.5" SSDs, and high-capacity SATA drives.

QTS Operating System
• With modularized multiple applications and functions, QTS enhances management efficiency, personal productivity, multimedia, and much more. Intelligent agent services have also been added to simplify system operations and management. The user-friendly QTS features an intelligent desktop that allows you to find desired functions quickly, monitor important system information on a real-time basis, open multiple application windows to run multiple tasks concurrently with greater working efficiency, and provides a built-in App Center with install-on-demand apps to extend NAS functionality.

Storage for Comprehensive Virtualization Applications
• The TS-873U is a comprehensive iSCSI/IP-SAN storage solution, and supports VMware, Citrix, Microsoft Hyper-V, and Windows Server 2012 R2, benefiting flexible deployment and management in virtualization environments. The TS-873U 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.

Integrated Virtualization and Container Solutions
• Virtualization Station allows you to host virtual machines (VM) on the TS-873U and access them via a web browser or Virtual Network Computing (VNC), while Container Station integrates LXC and Docker lightweight virtualization technologies for operating multiple isolated Linux systems on the TS-873U, as well as downloading apps from the built-in Docker Hub Registry. Container Station also supports the QIoT Containers platform that helps quickly structure your IoT environment and deployment on your private IoT cloud. No longer constrained by physical network performance, the Network & Virtual Switch increases data transfers between VMs, containers, and NAS through the internal interface.

Cross-Platform File Sharing and Sync
• The TS-873U centrally stores data, logs, and various files, and supports SMB/CIFS, AFP, and NFS protocols for file sharing across Windows, Mac, Linux/UNIX networks. Coupled with Qsync - a utility that turns a QNAP NAS into a safe, high-capacity data center for file synchronization - files uploaded to the TS-873U will be made available for all linked devices, such as computers, laptops, or mobile devices. You can sync shared folders and team folders for group file sharing, thus enhancing the flexibility of team projects and collaboration.

Backup & Disaster Recovery Solutions
• The TS-873U offers flexible backup solutions for Windows and Mac users, Volume/LUN snapshots (block-based LUN and file-based LUN), Folder snapshot, Snapshot Replica, and Clone. It also supports Hybrid Backup Sync that consolidates backup, restoration, and synchronization functions (using RTRR, rsync, FTP, and CIFS/SMB) for transferring data to local, remote, and cloud storage spaces as a comprehensive data storage and disaster recovery plan. Up to 256 snapshots per volume or LUN and a maximum 1024 snapshots per NAS. It is recommended to use block-based LUN snapshots.

Security to Protect Your Data
• In open network environments, business data may be exposed in a potential hack. The TS-873U provides numerous security options, such as antivirus, encrypted access, IP blocking, 2-step verification, and more. IT administrators can also control the access rights of each user to different folders, preventing unauthorized access to important files. The TS-873U supports AES 256-bit encryption, preventing sensitive business data from unauthorized access and breach even if the hard drives or the entire system were stolen. Windows AD server, LDAP server, and built-in LDAP service are also supported.

VPN & Proxy Server
• The QVPN app combines VPN Server and VPN Client functionality. Through QVPN, the TS-873U can be used as a VPN server with L2TP/ IPsec, OpenVPN, and PPTP support, allowing you to securely access data shared within the private local network. The TS-873U can also be used as a VPN Client to connect to other VPN servers or virtual private network through PPTP and OpenVPN for secure data transmission. VPN Client also allows your NAS to connect to multiple servers at the same time. You can connect your devices to your NAS and the VPN server at home to access data on the LAN; via VPN Client on your NAS you can connect to international VPN servers for accessing regionally-restricted services such as Netflix and Hulu in HD Station.

Qsirch
• The TS-873U provides Qfiling and Qsirch for organizing and searching for files, providing you with an efficient data storage center. Qfiling automates file organization - simply determine filing conditions, set a schedule, and files will be organized and archived based on your settings.
