To display and manage groups of datastore tiers at the private cloud level, go to Infrastructure view → Abstract datastore tiers. To manage these tiers, your user role must have privileges to infrastructure, as for datastore tiers. 
...
Abstract datastore tiers enable you to set cloud storage limits per tenant in more than one cloud location, including hard limits, that will block users, and soft limits, which can trigger a warning message for users or an event that you can capture and send as a lead to your cloud sales team!
And the Abstract datastore tiers widget will display storage usage and limits for the platform-wide service levels, which can each include multiple hypervisor datastores. You can rename this widget for your dashboard, as always.
...
And you can configure the display of this widget as usual, when you add it to your dynamic dashboards in the Home view.
...
To create a group tier for your datastore tiers, go to Infrastructure → Abstract datastore tiers, click the + add button, and enter a a Name.
...
To add service levels to the group, edit existing datastore tiers to assign them to the platform datastore tier group. Or create new ones and assign them.
To restrict the total storage that a tenant can use in a specific service level, add a limit for the platform tier. Just edit the enterprise and set the limit in Allocation limits.
Note that all the platform-wide storage service levels will display, even if the tenant does not have access to them.
...
So you will still need to grant the tenant access to individual tiers in each cloud location. Within each enterprise, when you edit the cloud location and go to limits, only the tiers that the enterprise can access will display.
You can also set limits for the cloud location only and they will be independent of the enterprise limits.
...
Abstract Abstract datastore tier limits per tenant apply to new deploys, reconfiguring VMs, and VMs that are captured from hypervisors or synchronized from public cloud to onboard them into the platform.
