GLYPH<SM590000> Currently not running on IBM Z servers: – No IBM Z skills – Want to implement cloud  – Have expectations that are acquired fromanother hypervisors’ management, such as  VMware, KVM, and Citrix E.3 DPM overview Traditional IBM Z servers are highly virtualized with the goal of maximizing the use of  compute (processor and memory) and I/O (storage and network) resources, and  simultaneously lowering the total amount of resources needed for workloads. For decades,  virtualization was embedded in the IBM Z architecture and built into the hardware and  firmware.  Virtualization requires a hypervisor, which manages resources that are required for multiple  independent virtual machines. The IBM Z hardware hypervisor is known as IBM Processor  Resource/Systems Manager (PR/SM). PR/SM is implemented in firmware as part of the base  system. It fully virtualizes the system resources, and does not require extra software to run. PR/SM allows the defining and managing of subsets of the IBM Z resources in LPARs. The  LPAR definitions include several logical processing units (LPUs), memory, and I/O resources.  LPARs can be added, modified, activated, or deactivated in IBM Z platforms by using the  traditional Hardware Management Console (HMC) interface. DPM uses all its capabilities as the foundation for the new user experience. In addition to  these capabilities, DPM provides an HMC user interface that allows customers to define,  implement, and run Linux partitions without requiring deep knowledge of the underlying IBM Z  infrastructure management; for example, input/output configuration program (IOCP) or  hardware configuration definition (HCD).
