 ## Create storage classes on top of existing storage
 
 By default, a new Kubernetes cluster only supports the local disk storage class, which stores data in a local disk. This class has limitations and can't be directly used in most production scenarios. For example, local disk volumes can only support `ReadWriteOnce` access mode, meaning the volumes can only be accessed by one pod at a time. However, [SQL Managed Instance enabled by Azure Arc](/azure/azure-arc/data/managed-instance-overview) requires [its backup volume to support the ReadWriteMany(RWX) access mode](/azure/azure-arc/data/create-sql-managed-instance?tabs=directly-connected-mode#create-an-azure-arc-enabled-sql-managed-instance), meaning the volume should support simultaneous reads and writes from multiple pods.
 
 Storage is important for any running systems, so most companies might have already set up storage infrastructures for existing systems. The Arc storage service provides a unified experience for creating storage classes on top of existing storage. With the Arc Storage Class service, cluster administrators only need to specify the name and type of the storage class to be created, and Arc Storage Class installs storage classes and their respective CSI components into their clusters. The installed components are managed by Azure, so updates are automatically installed and security vulnerabilities are automatically fixed.
