Virtualisation

    Virtualisation
                 Hardware Level – eg LPAR
                 Operating System Level
                      - eg Solaris Containers/Zones

How Oracle Recognises Virtualisation



                  Hard   Soft




 www.rocela.com
“Hard” Partitioning
• Oracle recognises various forms of server partitioning
  as “Hard” partitioning
• Some examples are as follows;
   – Solaris 10 Containers (capped containers only)
   – LPAR
   – DLPAR
   – Capped Micro-Partitions
   – vPar                                 Hard     Soft
   – nPar

 “Soft” Partitioning
• Oracle classes other forms of virtualisation as “Soft”
  Partitioning and views as a more flexible form of
  partitioning
• The processor capacity can be easily changed
• As such Oracle does not permit “Soft” partitioning as
  a means to determine or limit the number of software
  licences required for any given server
• Some examples of “Soft” partitioning;
    – VMware
    – AIX Workload Manager
    – HP Process Resource Manager

Oracle VM
• Oracle has it’s own form of virtualisation which can
  be used as soft or hard partitioning
• In most cases it is recognised as soft partitioning
• If the CPU binding is hardcoded then it could be
  recognised as hard partitioning
