NAS - TVS-H877AX-R5-16G - 8-Bay QuTS hero (6x 3.5in SATA + 2x U.2 NVMe slots) R5-7000 series

Introduction

Powered by an AMD Ryzen™ 7000 series 6-core processor and DDR5 memory, the TVS-hx77AX series combines ZFS data integrity with upcoming Qtier storage tiering technology to redefine performance standards for professional video collaboration and enterprise virtualization.

Zen Architecture & DDR5
AMD Ryzen™ 7000 series 6-core processor with up to 192 GB DDR5 memory (optional ECC), enabling heavy multitasking and high-load VM applications.

U.2 SSD Acceleration
Hybrid drive bays with U.2 PCIe Gen 4 NVMe SSD support, delivering massive bandwidth for virtualization, databases, and high-speed video workflows.

NFS over RDMA
Enable NFS over RDMA to bypass CPU overhead, transforming the NAS into high-throughput, low-latency direct storage for AI training and inference workloads.

10GbE & 2.5GbE
Built-in dual 10GBASE-T and dual 2.5GbE network ports to accelerate large file sharing and data-intensive transfers.

PCIe Gen 4 Expansion
Three PCIe Gen 4 slots for installing 25GbE NICs or discrete GPUs (NVIDIA RTX™ series).

Virtualization
Support for virtual machines and containerized applications, providing centralized storage, backup, disaster recovery, and storage expansion.

AMD Ryzen™ 7000 & DDR5: Pushing Multitasking to the Limit
Featuring the latest Zen 4 architecture AMD Ryzen™ 5 / 7 PRO 7000 series processors, delivering significant performance gains. Combined with expandable DDR5 memory up to 192 GB, it effortlessly handles demanding workloads including multiple virtual machines (VMs), containers, and high-resolution video transcoding.

Fusing U.2 NVMe Speed with HDD Capacity — Qtier Smart Tiering Coming Soon
Maximize storage efficiency without compromise. The TVS-hx77AX features dedicated 2.5-inch U.2 NVMe PCIe Gen 4 SSD slots for ultra-low-latency access. With the upcoming QuTS hero h6.0, Qtier storage tiering will be supported, allowing you to manually move hot data to high-speed SSDs while cold data remains on HDDs — achieving the perfect balance between performance and cost.

Powered by AMD Ryzen™ PRO 7000 Series 6-Core Processor
The TVS-h877AX features an AMD Ryzen™ 5 PRO 7645 processor (Zen 4 architecture), delivering exceptional multitasking performance and energy efficiency. Combined with 64 GB DDR5 memory and 3 x 25GbE SmartNICs, it achieves outstanding sequential throughput and random IOPS under high-load enterprise workloads.

NFS over RDMA | Unleash the True Potential of 25GbE
Eliminate CPU bottlenecks. NFS over RDMA transfers data directly between memory, delivering NVMe-like responsiveness to your workstation. This enables seamless integration with NVIDIA GB10 Grace Blackwell–powered AI supercomputers, significantly accelerating AI inference and fine-tuning workloads.

PCIe Gen 4 Expansion for Future Upgrades
The TVS-hx77AX features 3 PCIe Gen 4 slots, providing flexible hardware upgrades to meet growing business needs. Install 25GbE network cards for higher bandwidth, or add NVIDIA RTX™ 4000/5000 series graphics cards to boost AI computing and video processing capabilities.

The Ultimate Virtualization Workstation with GPU Passthrough
TVS-h877AX is a powerful platform for virtualization. Equipped with a high-frequency AMD Ryzen™ processor and supporting up to 192 GB DDR5 memory, it runs multiple virtual machines and containers simultaneously without performance lag. By installing a discrete graphics card (up to 200W) in a PCIe Gen 4 slot, GPU passthrough can be enabled for virtual machines, dramatically boosting graphics performance for design, engineering, or AI analytics workloads.

High Availability (HA) with Dual-NAS Failover
Prevent unexpected downtime and data loss.

Build an HA cluster using two TVS-h877AX units — one as the active server and the other as the passive server. When the active server encounters an unexpected failure, the passive server automatically takes over, providing instant protection. This ensures uninterrupted storage services and system availability.
