Presentation Script
Process Resource/Systems Manager (PR/SM) is a hardware facility of the
ES/9000 processor series that enables the resources of a single processor
complex to be divided between distinct, predefined logical machines called
logical partitions
(LPARs). A LPAR is a collection of resources including storage
(main and expanded), computation elements (vectors and ...
