SouthernCrossAI (SCX) has announced its integration into the Equinix Fabric AI ecosystem, marking a significant step in the expansion of sovereign AI inference capabilities across the Asia-Pacific region. The development enables enterprises, government agencies, and developers to access SCX’s ASIC-accelerated inference nodes through secure, low-latency private connectivity.
Through Equinix Fabric, organisations can now connect directly to SCX infrastructure without routing data through public internet pathways or offshore hyperscaler environments. The company said this approach is designed to ensure that data remains within locally governed infrastructure while enabling high-performance AI inference at scale.
SCX’s existing deployment at Equinix’s SY5 IBX data centre in Sydney forms the foundation of its operational network. The company confirmed that additional nodes across Equinix facilities in Australia will be rolled out progressively through 2026 and beyond, extending sovereign AI capacity to key enterprise and government markets.
“Joining Equinix Fabric AI ecosystem means that any organisation connected to Equinix Fabric can now reach our sovereign inferencing nodes with a private, direct connection,” said David Keane. “This is how we scale Australian AI — not by moving data overseas, but by making world-class inference available where Australian data already lives.”
Equinix Australia also highlighted the significance of the collaboration. “SCX represents exactly the kind of innovative sovereign AI provider that enterprises and government agencies need,” said Chris Johnston, Interim Managing Director of Equinix Australia. “Together, we are building the infrastructure for Australia’s AI future.”
Alongside the ecosystem integration, SCX confirmed that its national expansion will be powered by SambaNova Systems’s next-generation SN50 Reconfigurable Dataflow Unit (RDU). The chip is designed specifically for agentic AI inference workloads and will form the backbone of SCX’s multi-site infrastructure rollout across Australia.
According to SambaNova, the SN50 delivers up to five times the peak speed and more than three times the throughput of NVIDIA Blackwell B200 GPUs in agentic inference scenarios. The system operates at an average of 20 kilowatts per rack, allowing deployment in existing air-cooled data centres without requiring major infrastructure upgrades.
The SN50 architecture supports models of up to 10 trillion parameters and context windows extending to 10 million tokens. It also enables rapid model switching at millisecond latency, a capability increasingly required for multi-model AI workflows in enterprise and government environments.
SCX confirmed that SN50 deployment will begin as part of its national rollout across Equinix facilities in Sydney, Melbourne, and Brisbane. Additional nodes are expected to come online through 2026 and 2027, building a distributed sovereign inference network accessible through Equinix Fabric.
The SN50 is scheduled to begin shipping in the second half of 2026. Its integration positions Australia among the early adopters of next-generation AI inference infrastructure at sovereign scale.
As part of the partnership expansion, SambaNova Chief Revenue Officer Harry Ault visited Sydney to engage with customers and government stakeholders. He described Australia as a key market for sovereign AI development and highlighted SCX’s infrastructure approach as a model for regional deployment.
“The Asia-Pacific region represents one of the most significant opportunities for sovereign AI infrastructure globally,” Ault said. “SCX has built a full-stack platform combining world-class inference hardware with Equinix connectivity. The deployment of SN50 will be a defining moment for Australian AI.”
