Yeah, management server mount secondary storage.
Reason behind this is CS does patching of system vms by injecting systemvm.iso into system
vm. In this process, management server mounts secondary storage and copies systemvm.iso image
into secondary storage inside "systemvm" folder. Later that would be mounted by system vm.
During system vm startup there is a script "cloud-early-config" which installs the content
of mounted iso inside the system vm. 

Hope that clarifies.
