Line 8: ==PR/SM== Formally, LPAR designates the mode of operation or an individual logical partition, whereas PR/SM is the commercial designation of the feature.<ref name="Singh"/>{{rp\|83}} PR/SM (Processor Resource/System Manager) is a type-1 [[Hypervisor]] (a [[virtual machine]] monitor) that allows multiple ~~[[LPAR\|~~logical ~~partition]]s~~partitions to share physical resources such as [[Central processing unit\|CPU]]s, memory, [[Channel I/O\|I/O channels]] and LAN interfaces; the LPARs can share I/O devices such as [[direct access storage device]]s (DASD). PR/SM is integrated with all [[IBM System z]] machines. Similar facilities exist on the [[IBM Power Systems]] family, and its predecessors. [[IBM]] introduced PR/SM in 1988 with the [[IBM 3090]] processors.<ref>{{cite web\|url=http://www.redbooks.ibm.com/redpapers/pdfs/redp5157.pdf\|title=IBM Z Functional Matrix\|author1=Frank Packheiser\|author2=Octavian Lascu\|author3=Bill White\|page=18\|publisher=[[IBM]]\|date=2018}}</ref>
