If you want to use Azure Elastic SAN as data storage, you'll need an [Azure role-based access control (Azure RBAC) Owner](../../role-based-access-control/built-in-roles.md#owner) role on the Azure subscription. Owner-level access grants the Azure Container Storage extension the proper permissions to interact with Elastic SAN's API. If you're planning on using Azure Disks or Ephemeral Disk as data storage, you don't need special permissions on your subscription.

 - **Ephemeral Disk**: This option uses local NVMe drives or temp SSD on the AKS cluster nodes. It's extremely latency sensitive (low sub-ms latency), so it's best for applications with no data durability requirement or with built-in data replication support such as Cassandra. AKS discovers the available ephemeral storage on AKS nodes and acquires the drives for volume deployment.
