sharepoint online – What is the StorageQuotaAllocated media in SPO?

I have a little confusion about this property assigned to the storage quota in SharePoint Online.

If I ran Get-SPOTenantI get the StorageQuota: 1304576 Y StorageQuotaAllocated: 104962048.

StorageQuota The property makes sense, since it is my total storage of the tenant, which is 1.24 TB. But what is this? StorageQuotaAllocated (100TB) the numbers are

Note: I verify the quota assigned to all my sites in the tenant that 325TB (13 sites each with a limit of 25tb).

If I execute the Get-SPOGeoStorageQuota Then the results are the same as in our tenants administration page.

GeoLocation: NAM
GeoUsedStorageMB: 99
GeoAvailableMB Storage: 1304477
GeoAllocatedStorageMB: 0
TenantStorageMB: 1304576
Type of Fee: Assigned

Which is the StorageQuotaAlocated medium? Where do these numbers come from?
