T5-4 Memory Segment Aliagnment, How to Calculate

edited Jun 30, 2017 3:39PM in SPARC T-series servers (MOSC) 6 commentsAnswered

When making T5 memory segment assignemnest to LDOM's, what formula do I use to select a particular memory segment from one specific bank or another:

Example:

  Say I wanted to assgn memory to a specifc LDOM from each memory bank:

ldm add-memory mblock=0x4030000000:50G ldom1

ldm add-memory mblock=0x84000000000:50G ldom1

ldm add-memory mblock=0x104000000000:50G ldom1

ldm add-memory mblock=0x184000000000:50G ldom1

   How do I "CALCULATE" additional segments for additional domains of varing starting addresses and capacity????

Memory segments (4 banks):

                    *********MEMORY*********

         RA                            PA                               SIZE

=================================== 

         

    0x30000000                0x30000000       512G

    0x80000000000      0x80000000000    512G

    0x100000000000   0x100000000000   512G

    0x180000000000   0x180000000000   512G

Howdy, Stranger!
