The VAST DataStore

LDAP, Active Directory

• Secure multi-tenancy with multiple authentication sources. VAST DataStore supports LDAP, Kerberos, and Active Directory, enabling seamless integration into enterprise identity frameworks.

Multiprotocol ACL

• Safeguard multiprotocol access to any data with a unified permission model. VAST DataStore enforces consistent access controls across NFS, SMB, and S3 protocols, eliminating permission mismatches and simplifying policy management.

Directory and User Quotas

• Optimize resource utilization with granular quotas. VAST DataStore enables precise control over storage consumption at the directory and user level, helping you enforce usage policies, prevent overconsumption, and ensure fair resource allocation across teams and tenants.

Quality of Service

• Create optimized QoS policies for service levels with on-the-fly flexibility. VAST enables dynamic bandwidth allocation and prioritization across workloads, ensuring consistent performance for critical applications. Administrators can fine-tune service levels without downtime or reconfiguration.

Access Audit

• Monitor your VAST cluster with granular protocol and admin access audit logging. Capture detailed records of user activity across NFS, SMB, and S3, including authentication events and configuration changes. Strengthen your security posture and simplify compliance reporting.

Exabyte Scale Namespace

• Scale performance and capacity independently in a single massive namespace. VAST’s disaggregated architecture enables linear scaling across compute and storage, while maintaining global consistency and low-latency access. Manage billions of files and objects without fragmentation or rebalancing.

Metadata Index in the VAST Catalog

• Leverage a built-in, high-speed index of files with point-in-time granularity. The VAST Catalog continuously logs every file and object, enabling rapid metadata queries, historical snapshots, and semantic search across billions of records. Accelerate data discovery and governance at scale.

Snapshots and Object Immutability

• Protect data from ransomware and insider threats with indestructible storage. VAST DataStore combines scalable snapshots with object immutability to prevent tampering, deletion, or rollback. Immutable data structures ensure recovery integrity and protection across AI, analytics, and backup workloads.

Similarity-Based Data Reduction

• Leverage a breakthrough global data reduction algorithm that redefines the economic equation of flash. VAST DataStore’s Similarity engine uses advanced pattern matching to compress data across billions of files and objects, even those already deduplicated, delivering an average 3:1 effective savings across VAST’s installed base.

Capacity and Performance Analytics

• Monitor your workloads via the intuitive VAST UI or export metrics to the log analytics tool of your choice. Gain real-time visibility into system health, throughput, latency, and resource utilization. Proactively optimize performance and capacity planning with actionable insights across protocols and tenants.

Distributed/Multiprotocol File Locking

• Ensure consistency of operations across the cluster. VAST DataStore enforces distributed file locking across NFS, SMB, and S3 protocols, preventing conflicts and maintaining data integrity in multi-user environments.

Transactional Storage System

• Achieve the transactional guarantees of an ACID database with the performance of a parallel file system and the scale of an object store. VAST DataStore supports atomic operations, consistency, isolation, and durability across billions of files and objects, enabling reliable, high-speed data services.

Distributed Persistent Metadata

• Leverage non-volatile, cluster-wide metadata management for superior resilience, scalability, and performance. VAST DataStore distributes metadata across the cluster to eliminate bottlenecks and ensure durability.

Global Hyperscale Flash Translation

• Unleash the potential of ultra-dense, low-cost hyperscale flash for any workload while realizing a decade of SSD durability. VAST DataStore overcomes the limitations of raw QLC devices, delivering predictable performance and endurance at exabyte scale.

Encryption at Rest and in Flight

• Protect data in transit and stored on flash with advanced encryption.VAST secures every layer of the data path using AES-256 encryption for data at rest and TLS for data in flight.

Rapid Rebuild Erasure Coding

• Revolutionary erasure coding that rebuilds in a fraction of the time of Reed-Solomon codes with as little as 2.7% overhead. VAST DataStore’s advanced algorithms minimize recovery windows and reduce failure domain impact, ensuring fast, resilient rebuilds without compromising flash
