Partition Managers are users with administrative privileges allowing the creation and management of partitions in the overall system.
Only the System Administrator/Master User can designate other users as Partition Managers.
Further, only administrators can be designated as Partition Managers. See the FAQ "Why are there different types of users? What are they?" for more information.
Partition Managers are created and managed by the System Administrator/Master User in the User tools on the left side of the Remote Services web page.
