Why Now?

The Gap Between Enterprise Ambition and Data Reality

Storage silos and data fragmentation—driven by legacy architecture, M&A, and rapid tech adoption—make it hard for platform engineers and data scientists to reach the datasets they need, causing enterprise AI initiatives to faulter.

Storage Silos

For decades, IT teams ran three separate data silos for specific data types and use cases, piling on cost, complexity, and a wider attack surface.

Limited Visibility

Data engineers lack visibility across their entire data estate and the necessary permissions to access key data for model fine-tuning and inference.

Stale Data

AI is only as current as its data. Models running on stale data return outdated, inaccurate answers that erode user trust in the AI application.

Data Exposure

GDPR and EU AI Act compliance is non-negotiable, yet every data copy risks drift, inconsistent permissions, and exposing information that should stay protected.

We had great success with VAST in the past. So when we needed to replace storage in the arenas, we decided to future-proof ourselves by implementing VAST in all 32 arenas.

The VAST AI Operating System

One Storage Platform for the Enterprise

Consolidate Platforms

Run every data type and workload on a single all-flash system, retiring the sprawl of specialized storage systems.

Unify Business Data

A single global namespace lets data engineers discover and prepare data quickly, without sifting through silos.

Real-Time Insights

Event-driven workflows process and catalog new data the moment it lands, so it’s query-ready with no batch delays.

Consistent Security

Consistent permissions are enforced across all protocols and vectors on-prem and in the cloud, minimizing data exposure.

Use Cases

Breaking Down Legacy Silos with VAST AI OS

VAST AI OS provides the scalability, performance, and security needed to modernize applications, host traditional VMs, and unlock the full potential of generative AI.

Universal Storage

Universal Storage makes it easy to build a data foundation for enterprise apps and AI that is fast and affordable.

Unlike legacy NAS or SAN, VAST DataStore unifies file, object, and database semantics in a single platform. It eliminates tiering and rebalancing, provides ACID guarantees, and leverages similarity-based data reduction to make all-flash storage economically viable at exabyte scale.

VAST DataStore uses locally decodable erasure codes that restore data in a fraction of the time of Reed-Solomon with only 2.7% overhead. Combined with immutable snapshots and distributed metadata, it ensures data integrity, ransomware protection, and minimal downtime during failures.

VAST DataStore provides granular audit logs across NFS, SMB, and S3, capturing user activity, authentication, and admin changes. The logs integrate with SIEM and analytics tools, streamlining compliance with HIPAA, GDPR, and other standards. Immutable storage ensures audit data integrity.

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.
