5 x 25GbE iSCSI Random IOPS (4K)

Read speeds up to 1,253,234 IOPS and write speeds up to 791,094 IOPS.

Maximize storage efficiency. Manually move active data to high-performance SSDs and cold data to high-capacity HDDs.

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.

The TVS-h877AX 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.

Slot 1: PCIe Gen 4 x4

Slot 2: PCIe Gen 4 x8 (or x4)

Slot 3: PCIe Gen 4 x4

Note: When Slot 1 is not in use, Slot 2 provides PCIe Gen 4 x8 bandwidth; when Slot 1 is in use, Slot 2 provides PCIe Gen 4 x4 bandwidth.

The 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.

VMs

Run Windows, Linux, UNIX, and Android virtual machines directly on the NAS via Virtualization Station.

Containers

Run LXD and Docker containers for lightweight virtualization and microservices application development.

SR-IOV

Install a compatible PCIe network card (QXG-25G2SF-BCM and QXG25G2SF-E810) to enable SR-IOV for improved network resource allocation to virtual machines.

GPU

Directly assign a PCIe GPU to a virtual machine to meet the demands of tasks requiring high graphics computing power.

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.

Easy Management and Monitoring

Easily set up, remove, or rebuild clusters via the High Availability Manager application.

Ensure Data Consistency

Real-time data synchronization between active and passive servers minimizes data loss risk (RPO).

Ensure Critical Business Continuity

When the active server fails, the passive server can take over within 1 minute (RTO < 60 seconds).

Built a Smart Knowledge Hub with RAG Search

The TVS-h877AX integrates the Qsirch search engine with RAG technology, cloud-based LLMs, and generative AI to perform precise natural language searches across massive NAS file content, generating summaries and actionable insights.

Full-Text Search

Search files by file name, content, title, metadata, email subject and body, file path, and more.

Document Preview

Preview document content without opening files, view keyword-related paragraphs, and see sentences related to the file's topic.
