How do two P1 subscriptions under the same tenant split the Power BI environment?

[mmossel]

Would it be technically possible to have two P1 subscriptions under the same tenant, to allow splitting the complete Power BI environment, including workspaces, apps, and activity logs for example? What exactly is getting split, and what is not?

Access levels are not defined at the capacity level, it is defined at the workspace level. So no matter how many capacities you divide one into, if you assign a workspace to a premium capacity, if you give access to the workspace, the user will be able to access the report.

And if you are talking about accessing multiple reports which belong to different workspace in different premium capacities, it's possible to provide access to the reports which are hosted in different premium capacities. End users will never know the difference, as I said the access levels are maintained at the workspace level. 

And not only access levels, there will be no difference in auditing the activities. Even if you split a capacity into two, there will be two capacities created with two different capacity id's. So when you access a workspace, you can defferentiate the audit logs by the capacity id.

You can always upgrade or downgrade the capacity size. If you have a P2 (16 v-cores), you can split it into 2 P1 (8 v-cores each). And yes, you can have 2 P1 capacities under the same tenant.

@_sfrost I understand capacity sizing, I just don't understand well enough how it get's split when you do that?

For example, can one user then not access workspaces on P1 node from a different subscription? And, can admins only see activity log from the subscription that a certain workspace belongs to?
