Powered by AMD's powerful Ryzen processor, the TS-977XU delivers high system performance with up to 4 cores/4 threads and Turbo Core up to 3.4 GHz. The TS-977XU features a hybrid structure with four 3.5" HDD and five 2.5" SSD drive bays, allowing for enabling SSD caching and Qtier auto-tiering technology to greatly boost IOPS to meet the performance requirements of demanding applications. The TS-977XU features two SFP+ 10GbE ports and two Gigabit ports for high-speed connectivity, providing businesses and organizations with an ideal solution for quickly deploying a high-bandwidth, high-reliability storage environment.
Install up to five SSDs in the 2.5" drive bays to enable SSD caching and Qtier for optimal system performance.
Two 10GbE SFP+ ports provide higher bandwidth to empower applications like virtualization, 4K video editing and file sharing.
PCIe expandability allows for installing QM2 expansion card, USB 3.1 Gen 2 (10Gbps) cards, or wireless network cards.
Snapshots add an extra layer of protection for disaster recovery plans. You can set a custom snapshot schedule and can use snapshots to recover data from a local or remote NAS.
Scalable storage supporting virtualization, containerized apps, centralized storage, backup, sharing, and disaster recovery.
Besides using QNAP storage expansion enclosures, you can also leverage QNAP VJBOD technology to use the unused storage space from other NAS.
Top-class hardware engineering with high I/O expandability
The hardware design of the TS-977XU provides exceptional system performance and expandability to fulfill diverse application requirements.
Absolute performance with AMD Ryzen and up to 64GB RAM
Powered by a high-performance AMD Ryzen 3 1200 processor with AES-NI encryption acceleration and up to 64GB DDR4 RAM, the TS-977XU delivers aggressive yet power-smart performance to meet your multitasking demands. For resource-demanding business applications such as VDI, R&D, private cloud, and server virtualization, look no further than the TS-977XU.
Hybrid structure for enabling SSD and tiered storage
The TS-977XU features an HDD+ SSD hybrid structure (including five 2.5" and four 3.5" drive bays), allowing you to leverage the benefits of both hard drives and SSD to provide high storage capacity and high performance. Qtier Technology empowers the TS-977XU with automatic tiering that continuously optimizes storage utilization across high-performance SSD and high-capacity hard drives. 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.
SSDs and HDDs sold separately.
Dual-channel memory delivers power-smart performance
The TS-977XU supports dual-channel DDR4 memory and features four Long-DIMM slots. When using paired memory modules, the TS-977XU leverages the power of dual-channel architecture to boost performance. You can also customize the memory configuration (supports up to 64GB RAM) of the TS-977XU, making it the most ideal and cost-efficient storage solution for environments like virtualization that contain dynamically-changing workloads.
Extend NAS functionality with PCIe cards
The TS-977XU features a PCIe slot that allows for installing a 10GbE/40GbE network card, a QM2 M.2 SSD/10GbE PCIe card, or a wireless network card to provide greater application potential.
10GbE/ 40GbE adapters
Supports lightning-fast throughput for bandwidth-demanding tasks such as virtualization and fast backup/restoration for an ever-growing amount of data.
QM2 card with M.2 SSD/10GbE support
Add M.2 SSD caching or 10GbE (10GBASE-T) connectivity to the NAS to enjoy optimal performance.
Wireless network cards
Use with the WirelessAP Station app to transform the NAS into a convenient wireless base station, allowing network resources of the NAS to be shared with multiple devices.
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-977XU provides a 250 watt power supply and a PCIe slot that supports low-profile AMD Radeon or NVIDIA GeForce graphics cards that do not require additional power. Installing a graphics card can boost performance of applications such as video editing, 4K video transcoding, imaging processing in QTS and the performance of virtual machines via GPU passthrough.
Performance & reliability. Your wise choice.
The TS-977XU supports advanced business features to provide maximized efficiency and performance while ensuring 24/7 services.
USB 3.1
USB 3.1 Gen 2 (10Gbps) provides speeds up to 10Gb/s (double the speed of USB 3.0) to greatly boost data transfer performance, allowing for transferring large files faster and more easily.
Central management
Designed for IT administrators, QRM+ provides a single-point solution to discover, map, monitor and manage all Windows, Linux and IPMI devices in your network, and facilitates device discovery with a graphical topology diagram
Optimized performance for VMware Virtualization with iSER
With the built-in dual 10GbE ports that natively features Mellanox ConnectX-4, the TS-977XU supports the iSCSI Extensions for RDMA (iSER) protocol to boost data transfer performance of the TS-977XU as VMware ESXi storage and to reduce the CPU load of the ESXi server. iSER can provide a significant increase in performance, providing an essential tool to optimize demanding virtualization applications.
Block-based iSCSI LUN: Ideal choice for virtualization storage
The TS-977XU supports block-based iSCSI LUN that provides a more reliable and isolated environment than file-based LUN. Supporting VMware, Citrix, Microsoft Hyper-V and Windows Server 2016, the TS-977XU provides a high-performance, reliable and affordable storage solution for virtualization environments, while also supporting 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 and QNAP SMI-S provider with enhanced operational efficiency and management in virtualization applications.
All-in-one server to host virtual machines and containers
Virtualization Station and Container Station jointly introduce a hybrid approach to virtualization. No matter your virtualization needs, you can count on QNAP for complete virtualization support.
Virtualization Station
Virtualization Station allows you to run multiple Windows, Linux, UNIX and Android virtual machines and access them via a web browser or VNC (Virtual Network Computing). Businesses can run virtualized server applications on a single NAS without the need for additional physical servers.
Container Station
Container Station integrates LXC and Docker lightweight virtualization technologies. You can download apps from the built-in Docker Hub Registry. It supports container import/export and permission settings. It's easy deployment, portable, and efficient.
Upgrade your IT environment with QNAP's fast and affordable 10GbE Switch!
QNAP 10GbE/NBASE-T unmanaged switches allow you to instantly upgrade your network environment at a cost-effective price. With a 10GbE network you can enjoy blazing-fast transfer speeds, empower bandwidth-demanding tasks like virtualization, and enable simultaneous real-time access to large NAS-based files using multiple workstations (ideal for video editing and multimedia). QNAP also provides a 10GbE PCIe network expansion card for Windows/Linux PCs to take advantage of high-speed LAN environments.
Optimized collaboration with seamless file sharing and sync
The TS-977XU centrally stores data and files, and supports SMB/CIFS, AFP and NFS protocols for file sharing across Windows, Mac, and Linux/UNIX networks. Coupled with Qsync (a utility that turns a QNAP NAS into a safe, high-capacity data center for file synchronization) any file uploaded to the TS-977XU 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 to enhance the flexibility of team projects and collaboration. Files can be centrally managed using File Station, including files from mobile devices and optical disc drives. File Station also allows you to mount a remote NAS, and transfer files between your NAS and public cloud services for greater convenience.
Complete backup planning
The TS-977XU provides a reliable, flexible backup & disaster recovery solution to assist organizations in routine backup jobs with cost-efficiency and high productivity.
Windows and Mac backup
Use the license-free QNAP NetBak Replicator utility to back up/restore files on Windows devices. Time Machine is also supported for Mac users.
Hybrid Backup Sync
