Scaling from petabytes to exabytes exposes the limits of storage built for a single dimension. Peak performance is table stakes, and the strain surfaces elsewhere: unpredictable behavior, inflexibility under shifting demand, and infrastructure sprawl, all consuming scarce engineering attention.
VAST AI Operating System for Model Training
Meet the Data Demands of Frontier Training with VAST
Scale to exabytes of storage across file, object, block, and tabular data with a single, reliable platform. The VAST AI OS delivers the consistent performance demanded by frontier training across all modalities with over 99.999% uptime.
Storage at Scale for AI Training
At Frontier Scale, Storage Stops Getting Out of the Way
Infrastructure You Can’t Stop Watching
Storage that performs inconsistently quietly drains training goodput, and storage that becomes unresponsive stalls thousands of GPUs while engineers debug.
Isolation at the Cost of Utilization
Training demands on storage shift constantly. Packing preprocessing, data loading, and checkpointing onto one system risks interference, so multiple systems are deployed and capacity becomes stranded.
Operational Overhead and Sprawl
Engineering attention is the scarcest resource, yet growing tenfold often means tenfold the tuning, migrations, and separate silos, each with its own technology to master.
