HP HPE XP P9500 Manual page 7

The controller chassis includes the following maximum number of components: two service
processors, 512 GB cache memory, four grid switches, four redundant power supplies, eight
channel adapters, four disk adapters, and ten dual fan assemblies. It is mounted at the bottom
of the rack because it is the heavier of the two units. If a system has two SVPs, both SVPs are
mounted in controller chassis #0.
The following illustration shows the locations of the components in the controller chassis.
