    Check QNAP NAS with Support for Virtualization application

    Transform your network with a wallet-friendly 2.5GbE switch

    Upgrading your network shouldn’t break the bank, and 2.5GbE connectivity provides immediately noticeable improvements compared to standard 1GbE. QNAP offers 2.5GbE switches that supports Multi-Gigabit NBASE-T™ and allows you to use existing CAT5e cables to connect multiple computers and NAS, assisting organizations in implementing high-speed, secure and scalable network environments without going over budget.

    Switch operating systems for optimal data integrity and reliability

    The TS-873A also supports QuTS hero - QNAP’s ZFS-based NAS operating system. Providing end-to-end data integrity, data reduction (inline data deduplication, compression and compaction), and much more, QuTS hero uses additional system resources to ensure an optimal environment for protecting business data.

    1. QTS and QuTS hero use different file systems. You must remove all the drives from the TS-873A before switching from QTS to QuTS hero.
    2. QuTS hero requires a NAS with at least 8 GB memory.
    3. Inline Data Deduplication requires a NAS with at least 16 GB memory (at least 32 GB memory is recommended for optimal performance).
    4. It is recommended to create an SSD RAID with at least two SSDs for the QuTS hero system drive to attain optimal system performance. Please note that M.2 SSD hot-swapping is only supported by M.2 SSD slots on PCIe cards (such as the QM2). M.2 SSD slots that are built into the NAS do not support hot-swapping.

    Obtain performance benefits from M.2 SSD caching

    The TS-873A features 2 M.2 NVMe SSD slots for you to enjoy SSD caching or Qtier auto tiering Technology

    Improve random data access speeds with an SSD cache
    SSD caches accelerate IOPS performance and reduce latency for storage volumes. They are perfect for IOPS-demanding applications (including databases and virtualization) and can significantly improve overall workflows.

    Maximize the value of SSDs with Qtier Technology
    Qtier™ Technology empowers the TS-873A with auto tiering that helps continuously optimize storage efficiency by automatically moving data between M.2 SSDs, 2.5-inch SSDs, and high-capacity HDDs based on the data's access frequency. 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 SSDs.

    Note: Qtier Technology is supported by QTS

    Upgrade to 10GbE and abundant capability with PCIe expansion

    The TS-873A features two PCIe Gen 3 x4 slots that allows for various expansion cards for expanding application potential.

    Note: TS-873A uses high-profile expansion cards

    SAS/ SATA expansion card

    Designed for connecting the TS-873A to TL SATA, TL SAS and REXP expansion units to increase storage capacity.


    5GbE/10GbE network card

    Enable lightning-fast throughput for bandwidth-demanding tasks, such as virtualization, massive data transmission, and fast backup/restoration.


    QM2 M.2 SSD/10GBE CARD

    Adds M.2 NVMe SSD/ SATA SSD caching or 10GbE (10GBASE-T) connectivity to the NAS for optimized performance and bandwidth.


    USB 3.2 GEN 2 (10GBPS) expansion card

    Enjoy higher network speeds or boost the USB connectivity for faster file transfer.


    Wi-Fi 6 wireless adapter

    Install a PCIe 802.11AX network adapter (based on the Intel® AX200) in your NAS to create a seamless Wi-Fi 6 network environment or add a QWA-AC2600 wireless adapter with WirelessAP Station to build a wireless access point.


    SAS/ SATA expansion card

    Designed for connecting the TS-873A to TL SATA, TL SAS and REXP expansion units to increase storage capacity.


    5GbE/10GbE network card

    Enable lightning-fast throughput for bandwidth-demanding tasks, such as virtualization, massive data transmission, and fast backup/restoration.


    Easy and Secure File Management

    File Station allows direct management of files stored on the TS-873A and in the cloud. Users can easily upload files from their PC, drag/drop files between folders, rename/delete files, and configure file/folder permissions to prevent unauthorized access. Microsoft Office Online can also be used to directly view/edit Microsoft Office documents stored on the TS-873A. Confidential/sensitive data can be encrypted to add extra security.

    Install a graphics card for GPU-accelerated computing

    Graphics cards are optimized for graphical calculations and transformations, but require significantly more power than other hardware. The TS-873A features PCIe slots to support high-profile graphics cards that do not need power cables, including NVIDIA® GeForce® GTX1650 graphics cards to boost performance of applications such as video editing , 4K UHD transcoding, imaging processing in QTS and performance of virtual machines via GPU passthrough.

    1. Supported video formats depend on the hardware and software specifications of the devices. Playback capability and quality may vary due to factors including the original file formats/quality, hardware and software limitations, and output devices.
    2. When Virtualization Station uses graphics cards, the NAS will temporarily stop hardware transcoding acceleration for QTS (and vice versa).
    3. Consult the Compatibility List for information on supported NAS and graphics cards.

    Build an affordable Fibre Channel SAN environment

    Common Fibre Channel Storage Area Networks (SAN) devices are often costly. By installing a QNAP 16Gb Fibre Channel card (QXP-16G2FC 16Gb) in the TS-873A, you can set a Fibre Channel Target using the iSCSI & Fibre Channel app. Moreover, the LUN Masking and Port Binding features provide an additional layer of data security.

    High-speed 2.5GbE VM Backup Solution

    With Hyper Data Protector, the TS-873A becomes an agentless backup tool for unlimited VMware® vSphere and Microsoft® Hyper-V VM backup. Hyper Data Protector features incremental backup, global deduplication, backup scheduling and recovery compression. With 2.5GbE connectivity, backup and restoration times are greatly reduced, providing a cost-effective solution for disaster recovery.
