Supported protocols
Dedicated VAST supports all built-in VAST protocols, including NFS, S3, NVMe/TCP, and SQL, so you can connect workloads that use different access patterns.NFS
Standard POSIX filesystem access. Suitable for most AI/ML training and inference workloads that read and write files directly. Dedicated VAST supports multi-path NFS, which distributes NFS traffic across multiple network paths to increase throughput and resilience. For multi-path configuration details, see the VAST NFS multi-path documentation.S3
S3-compatible object storage access served directly by your Dedicated VAST cluster. This is the cluster’s built-in S3 endpoint, separate from CoreWeave AI Object Storage. S3 credentials are tied directly to VAST VMS user accounts. The same user identity governs both file and object access. For multi-tenant S3-compatible storage that does not require dedicated infrastructure, see CoreWeave AI Object Storage.NVMe/TCP (block)
High-performance block storage access using NVMe over TCP. Dedicated VAST lets you provision paths as block storage subsystems and partition cluster capacity as block storage volumes, without requiring specialized networking hardware such as Fibre Channel or InfiniBand. You provision block storage through VMS, the VMS REST API, or the VAST Block CSI Driver for Kubernetes. For block storage configuration details, see the VAST block storage documentation.SQL
Direct SQL query access to VAST DataBase. Lets analytics workloads query data stored on VAST without ETL or external data movement. For more information about DataBase, see Data services.VAST Views
A View is VAST’s protocol abstraction layer. Each View maps a filesystem path (or path subtree) to one or more protocols and carries the configuration for how VAST exposes that path: mount options, access permissions, and protocol-specific settings. Separate Views can expose a single path simultaneously over NFS, S3, SQL, and block, so different consumers can access the same underlying data through their preferred interface. You manage View configuration in VMS. For configuration details, see the VAST Administrator’s Guide.Kubernetes and CSI drivers
Kubernetes PVCs on Dedicated VAST use the standard VAST CSI drivers. VAST provides separate drivers for file and block storage:- VAST CSI Driver: Manages file-based PersistentVolumes (NFS). Deploys controller and node pods for volume lifecycle operations (create, delete, and resize) and mount handling. For more information, see the VAST CSI Driver documentation.
- VAST Block CSI Driver: Manages block-based PersistentVolumes (NVMe/TCP). For more information, see the VAST block storage documentation.
