You use Companies Storage Spaces Direct. You need to view the available storage in a Storage Space Direct storage pool. What should you use?

File Server Resource Manager (FSRM) is used for managing quotas, file screening, and storage reports on file servers, not for viewing the overall available capacity of an S2D storage pool itself.

The Get-StorageSubsystem cmdlet is a PowerShell command that retrieves storage subsystem objects and can be used in scripts, but it is not a direct, graphical tool to view available storage for an end-user.

Disk Management is a snap-in for managing individual disks and volumes, but it does not provide a holistic, pooled view of a Storage Spaces Direct environment or its aggregated available capacity across multiple nodes.

Windows Admin Center is the primary graphical management tool for Storage Spaces Direct (S2D) and offers a comprehensive dashboard to monitor, manage, and view details about S2D clusters. It provides intuitive visualizations of storage pools, volumes, drives, and their available capacities, making it the most suitable and recommended tool for viewing available storage.
