Which predefined role serves as the data storage VM superuser?

The predefined role that serves as the data storage VM superuser is known as "vsadmin." This role is specifically designed to manage storage resources within a virtualized environment, ensuring that the user has sufficient permissions to perform necessary administrative tasks related to data storage virtual machines (VMs). The vsadmin role allows for comprehensive access to storage configurations, data management, and can facilitate operations that require elevated privileges for effective management of storage solutions.

In the context of storage virtualization, the vsadmin role is critical for tasks such as provisioning storage, configuring networking options for VMs, and managing data policies, all of which are essential for maintaining the efficiency and performance of storage systems in a virtualized setup. This role emphasizes the importance of specialization in the management of VMs and storage resources, which is necessary for optimal performance and data protection.

Roles like admin and superuser might include broader system-wide permissions that could span beyond storage-specific tasks, while the storage-admin role is focused on storage functionalities but may not encompass the full range of actions permitted to a superuser specifically designed to manage data storage VMs.
