VAST DataSpace
The Global Data Fabric for AI and Analytics
Unify data across edge-to-cloud environments in one global fabric that delivers all-flash performance and strict consistency for AI and analytics everywhere.
Legacy Challenges
Why Global Data Access Has Always Fallen Short
Legacy global-namespace systems promised anywhere-access but delivered latency, inconsistency, and lock-in. The VAST DataSpace breaks those limits with a global data fabric that unifies clusters worldwide while preserving strict transactional consistency.
Slow and Inconsistent Writes
Legacy global namespaces drag performance down to WAN speeds. The VAST DataSpace decentralizes fine-grained locks and leases, enabling local speed writes with strict consistency across sites.

A global data fabric connects edge, core, and cloud environments into a single, consistent data space. It eliminates latency, inconsistency, and data silos caused by separate storage or replication systems. The VAST DataSpace delivers strict consistency and local-speed access everywhere, giving AI and analytics real-time visibility into enterprise data without the complexity of legacy global-namespace solutions.
The VAST DataSpace uses decentralized locks and leases to maintain strict consistency while allowing local-speed reads and writes at every location. Unlike systems that rely on eventual synchronization, it enforces real-time coherency through write leasing and intelligent caching. The result is immediate data access without WAN latency or conflicts; performance and consistency without compromise.
Yes. The VAST DataSpace delivers globally distributed data to wherever compute is available—on-premises, in the cloud, or at the edge. Its adaptive synchronization modes pre-stage or fetch data dynamically, ensuring every GPU, CPU, or analytics node runs on current information. The platform removes the need to move entire datasets, accelerating model training and inference at global scale.
Traditional replication systems copy whole datasets on a schedule, creating stale views and squandering bandwidth. The VAST DataSpace synchronizes only the blocks that change, using predictive prefetch and adaptive modes (Lazy, Eager, Schedule) to keep data aligned with compute demand. This architecture delivers continuous, fine-grained consistency with minimal network overhead.
Absolutely. VAST Cloud Instances run natively in AWS, Azure, and Google Cloud, allowing cloud compute to access on-premises data with local performance. Ephemeral instances cache data for burst workloads, while persistent instances mirror writes for full durability. Together, they extend your global namespace seamlessly into any cloud region without re-architecting applications.
