What command shows all available storage in a VPLEX system?

The correct response indicates that the "Performance Dashboard" is utilized to view all available storage in a VPLEX system. This dashboard serves as a comprehensive interface that presents not only storage availability but also other performance metrics related to the entire system. It provides a visual representation of resource utilization, helping administrators to quickly assess the status of storage assets within the VPLEX environment.

In contrast, the other options serve different functions or may not exist within the VPLEX command set. For example, the command that specifically focuses on showing storage status or availability might seem relevant but doesn't encompass the broader data and performance analysis presented by the Performance Dashboard. The systems in VPLEX use a range of specific commands and reports, yet a performance dashboard synthesizes those into a user-friendly interface, effectively summarizing the entire storage landscape in a single view.
