Our AI servers are built to be the most power efficient on the market with advanced electrical design, intelligent distribution and redundant power systems. Our infra, chips, models and software are designed to minimise energy use and maximise value per watt utilised.

Our novel prototype immersion cooling GPU cluster is an Australian first with significant energy benefits. Our closed cooling loops eliminate evaporation and drastically reduce water demand.

Our segregated high-performance network includes hardware management, hypervisor and cluster management, inference serving networks, and training networks with extreme east–west bandwidth (400–800 Gbps per node), enabling frontier model training. Redundancy includes multi-path fibre and automatic failover provide resilience and continuous availability.

Dense GPU servers with NVLink and PCIe Gen5 architectures. CPUs include high-core-count for orchestration, preprocessing and hybrid applications. Hot NVMe-based distributed storage for active training datasets, and cool erasure-coded object storage for archival and compliance requirements.

As we’re colocated in major DCs, cross connects are fast and secure. Ideal for connecting your AI workloads to other devices, networks or DCs, all while avoiding the public internet.

For each server or workstation, Zai Node provides fully certified Hardware Manifest and Attestation documentation, ensuring security protocols are met.

Spin up and spin in <24 hrs also with controls to stop unexpected run times.

Unlike hyperscalers, Zai Node makes our infra open for physical and digital third party inspections and verifications.

Our servers and workstations are accompanied by a Certificate of Australian Origin.
