2.7.1 Implementing VM2000
Depending on the architecture of the Server Unit there are two fundamentally different
technical implementations of VM2000.
Implementation principle for SU /390
On SU /390 VM2000 controls the hardware of the Server Unit.
The VM2000 monitor manages all VMs and provides its functions via the VM2000 interface.
The VM2000 hypervisor controls execution of all guest systems on the VMs. Differentiated
scheduling mechanisms ensure optimum execution of the guest systems.

In this case, HSI stands for "Hardware Software Interface". Further information is provided
in the "VM2000" manual [12].
