Logical Partitioning of Memory

The memory size to be allocated to each LPAR can be specified for each LPAR
(in multiples of 256 MB). Each guest OS has an exclusive use of the memory
assigned to its LPAR. LPAR manager automatically determines which physical
memory offset area(s) to allocate to an LPAR when the LPAR is activated.
