What is the QNAP TVS-h877AX-R5-16G?
The TVS-h877AX-R5-16G is an eight-bay hybrid desktop NAS running the QuTS hero operating system. It provides six 3.5-inch SATA drive bays, two U.2 NVMe PCIe Gen 4 x4 bays, 16GB DDR5 memory, integrated AMD Radeon™ Graphics and three PCIe Gen 4 expansion slots.
AMD Ryzen™ 7000 Series and DDR5 Memory
Zen 4 processing and expandable DDR5 memory support demanding multitasking.
The TVS-h877AX-R5-16G uses an AMD Ryzen™ 5 7000 series 6-core/12-thread processor with integrated AMD Radeon™ Graphics. Its 16GB UDIMM DDR5 memory can be expanded to 192GB across four DDR5 slots, with optional ECC memory support.
This platform is designed for heavy multitasking, high-load virtual machines, containers and high-resolution video transcoding.
Hybrid SATA and U.2 NVMe Storage
Combine high-capacity hard drives with high-speed U.2 NVMe SSD storage.
Six SATA Drive Bays
Six 3.5-inch SATA bays support 3.5-inch SATA hard drives and 2.5-inch SATA solid state drives.
Two U.2 NVMe Bays
Two 2.5-inch U.2 NVMe PCIe Gen 4 x4 bays support compatible PCIe Gen 4 and PCIe Gen 5 U.2 SSDs.
SSD Cache Acceleration
SSD cache acceleration is supported for workloads that benefit from faster storage access.
High-Speed Networking and Expansion
Built-in multi-gigabit connectivity with flexible PCIe Gen 4 expansion.
Dual 10GBASE-T
Two 10GBASE-T ports support 10G, 5G, 2.5G, 1G and 100M network speeds.
Dual 2.5GbE
Two additional 2.5GbE ports support 2.5G, 1G, 100M and 10M connectivity.
Three PCIe Gen 4 Slots
Three PCIe Gen 4 slots support expansion including optional 25GbE adapters and discrete GPUs, including NVIDIA RTX™ series cards.
Virtualization, NFS over RDMA and GPU Support
Designed for centralized storage, virtual workloads and low-latency data access.
The TVS-h877AX supports virtual machines and containerized applications for centralized storage, backup, disaster recovery and storage expansion. GPU pass-through is also supported.
NFS over RDMA can bypass CPU overhead to provide high-throughput, low-latency direct storage for supported AI training and inference workflows.

QuTS hero and Qtier Information
ZFS-based storage integrity with supplied information about current and upcoming tiering functions.
The TVS-h877AX uses the QuTS hero operating system. The supplied product content describes Qtier for QuTS hero as allowing active data to be moved to high-performance SSDs and cold data to high-capacity HDDs.
The same supplied content also describes upcoming Qtier smart tiering technology. Availability and the exact level of automatic data migration should therefore be confirmed before relying on this feature.
Frequently Asked Questions
Quick answers about the TVS-h877AX-R5-16G.
How much memory is installed?
This configuration includes 16GB UDIMM DDR5 memory. The NAS supports up to 192GB across four DDR5 slots and supports optional ECC memory.
Which drives does the TVS-h877AX-R5-16G support?
The six 3.5-inch bays support 3.5-inch SATA hard drives and 2.5-inch SATA SSDs. The two 2.5-inch bays support U.2 SSDs, with U.2 NVMe compatibility limited to PCIe Gen 4 and PCIe Gen 5 SSDs.
Are the U.2 SSD bays hot-swappable?
Yes, with a condition: to enable hot-swap after system startup, the U.2 SSD must be installed before the NAS is powered on.
What network ports are built in?
The NAS includes two 10GBASE-T ports and two 2.5GbE ports. Optional 25GbE connectivity can be added via an adapter.
Does it support PCIe expansion?
Yes. It has three PCIe Gen 4 slots, with Slot 1 operating at Gen 4 x8 when Slot 2 is unused or Gen 4 x4 when Slot 2 is in use.
Does it support virtualization and GPU pass-through?
Yes. The supplied information lists support for virtual machines, containerized applications and GPU pass-through.
What is the standard warranty?
The supplied datasheet lists a standard five-year warranty.
U.2 hot-swap note: A U.2 SSD must be installed before the system is powered on to support hot-swapping after startup.
Memory note: For dual-DIMM configurations, use a pair of identical DDR5 modules. Use QNAP memory modules with identical specifications and refer to the hardware user manual before installation.
