# About VAST Block CSI Driver

## Overview of VAST Block CSI Driver

VAST Block Storage CSI Driver allows container orchestration frameworks such as Kubernetes to dynamically provision NVMe-based block storage on a VAST cluster.

With VAST Block CSI Driver, you can:

- [Provision](/develop/docs/provision-block-storage-with-vast-block-csi-driver-2-7#vast-block-csi-driver-workflow) block volumes based on multiple Kubernetes storage classes
- [Provision](/develop/docs/provision-block-storage-with-vast-block-csi-driver-2-7#provision-ephemeral-block-volumes) ephemeral block volumes
- [Provision](/develop/docs/provision-block-storage-with-vast-block-csi-driver-2-7#provision-static-volumes) static block volumes
- [Protect](/develop/docs/protect-block-volumes-with-vast-snapshots-and-clones-2-7#overview-of-vast-snapshots-and-clones) the block volumes being provisioned with VAST snapshots and clones
- [Replicate](/develop/docs/replicate-block-volumes-with-vast-csi-replication-operator-2-7) block volumes to another VAST cluster

VAST Block CSI Driver capabilities include:

- [Support](/develop/docs/provision-block-storage-with-vast-block-csi-driver-2-7#provision-block-volumes-on-multiple-vast-clusters) for multiple VAST clusters
- [Support](/develop/docs/about-vast-block-csi-driver-27#support-of-vast-cluster-multitenancy-for-block-storage) for multiple VAST cluster tenants
- [DNS-based resolution](/develop/docs/provision-block-storage-with-vast-block-csi-driver-2-7#set-up-dnsbased-virtual-ip-resolution-for-block-volumes) of virtual IPs

> **Note:** VAST Cluster 5.3 or later is required for block storage provisioning.

VAST Block CSI Driver can be deployed using one of the following methods:

- [Helm chart-based deployment](/develop/docs/deploy-vast-block-csi-driver-2-7#steps-to-deploy-vast-block-csi-driver)
- [VAST CSI Operator for Kubernetes](/develop/docs/deploy-vast-block-csi-driver-2-7#deploy-vast-block-csi-driver-with-vast-csi-operator-for-kubernetes)
- [VAST CSI Operator for OpenShift](/develop/docs/deploy-vast-block-csi-driver-2-7#deploy-vast-block-csi-driver-on-openshift-with-vast-csi-operator)
