7.3 Creating an IBM i 6.1 partition
Using Integrated Virtualization Manager (IVM) to create an IBM i 6.1 partition is
similar to using the HMC. IVM uses a number of defaults that simplify partition
creation. For example, because IBM i 6.1 partitions cannot own physical
hardware on an IVM-managed system such as a BladeCenter JS23/JS43, those
screens are omitted from the creation wizard. Other screens are simplified as
well that relate to shared processor pool settings and memory settings. Typically
you will need to tailor the partition properties to change the settings so they are
more granular.
One other difference between the HMC method and using IVM, if you are familiar
at all with the HMC you know that the partition has properties and the partition
profile contains the definition of your selections for hardware, load source,
console etc. With the HMC you may even have multiple partition profiles for one
partition. In IVM, there is only one entity that describes both the partition
properties and the partition profile. There are not separate partition profiles in
IVM.
Since your IBM i partition is virtual, IVM defaults the load source and alternate
IPL adapters to the Virtual SCSI client adapter in the IBM i 6.1 partition, and the
console adapter to the first Virtual Ethernet adapter. If you plan to use separate
Virtual Ethernet adapters for LAN console and production traffic, and you want to
use the second Virtual Ethernet adapter for the LAN console, you can make the
change in the partition properties.
7.3.1 IBM i 6.1 minimum requirements
The minimum recommended amount of memory for an IBM i 6.1 client partition
on the BladeCenter JS23/JS43 blade is 1 GB. If you running two or more
IBM i 6.1 partitions on the same blade, ensure there is enough memory on your
blade.
The actual memory and CPU values should be sized individually for each IBM i
6.1 workload using the IBM Workload Estimator, which is available at:
http://www.ibm.com/systems/support/tools/estimator/index.html
Note: Also consider the system firmware or POWER Hypervisor for the
BladeCenter JS23/JS43 blade will allocate some memory for its usage. This
amount will vary but is generally less than 1GB. This value can be found on
the main panel of IVM listed by Reserved firmware memory.
