How can I assign a hardware tier to an organization?

The organizational structure in Domino can be used to provide group level permissions to a set of users.  If for example, you have an expensive GPU tier that you would like to assign access to for a set of users it can be done from the organization administration screen.  

Navigate to Admin>>Users>>Organizations>>hardware tiers and select which hardware tiers you would like the org to have access to.  Note that global tiers are accessible to all orgs by default.
