Exascale HPC Performance. Enterprise Simplicity.
No kernel rebuilds. No patch cycles. No downtime.
Run your most demanding HPC and AI workloads with the performance and scale of a parallel file system and the simplicity of NAS, at archive economics. Built on DASE (Disaggregated and Shared Everything), VAST AI OS decouples compute from storage so everything runs on one all-flash platform, without the rigidity and overhead of legacy architectures.

Built for the I/O Demands of Modern HPC
Keep GPUs and CPUs Fed. Always.
A fully parallel data and metadata path sustains throughput at any scale, across mixed sequential MPI and random AI I/O patterns. The exact workload profile that degrades Lustre and GPFS under load. Long-running simulations and multi-week AI training runs complete on schedule, without stalls or retries.

Scale to Exabytes Without Re-Architecting.
DASE decouples storage media from the servers that manage it. Capacity and performance scale independently, live, with no namespace fragmentation, no disruptive rebalancing, no cluster downtime. Proven in deployments beyond 100 PB. The same architecture that runs petabytes today scales to exabytes tomorrow without a forklift.

Operations That Run Themselves.
Standard NFS delivers parallel file system performance. No proprietary client stack, no kernel rebuilds, no version matrix to manage. Rolling upgrades and self-healing run with zero downtime. Multi-week jobs survive infrastructure changes without interruption.
