Depending on the architecture of the Server Unit, there are fundamentally different technical solutions for VM2000.
Implementation principle for SU /390
On SU /390, VM2000 controls the hardware of the Server Unit.
The VM2000 monitor manages all the VMs and provides its functions via the VM2000 user interface.
A VM2000 hypervisor controls the execution of all guest systems on the VMs. Sophisticated scheduling mechanisms ensure that the guest systems run as efficiently as possible.
Detailed information can be found in the section "Implementation on SU /390".
Implementation principle for SU x86
On SU x86, the X2000 carrier system controls the hardware of the Server Unit.
The VM2000 monitor manages the VMs with the guest system BS2000 (BS2000 VM) and provides its functions via the VM2000 user interface.
The Xen hypervisor virtualizes the global resources CPU and main memory, controls the execution of all VMs (scheduling), and performs load balancing for CPU utilization.
The central manual for operating SE servers is the manual “Operation and Administration” [19]. A detailed description of working with the SE manager is also provided there.
