148 Logical Partitions on System i5
5.2.6 Partition memory
Figure 5-7 shows the initial partition memory panel that is displayed. Memory can be
allocated in a combination of megabytes (MB) or gigabytes (GB). Megabyte allocations are
restricted to multiples of the logical memory block size. Currently, the value for the logical
memory block size is 16 MB.
Notice that the default MB values do not automatically disappear when you add values into
the GB window. These values must be removed manually. Also, the 128 MB minimum value is
too small a minimum for an i5/OS partition.

There are three memory values for a partition profile:
򐂰 Minimum memory: This amount of memory is required for the partition. The profile will fail
to activate if the minimum memory is not met.
򐂰 Desired memory: This is the requested amount of memory for the partition. On profile
activation, the partition will receive an amount of memory between the minimum and
desired amounts depending on what is available.
򐂰 Maximum memory: The maximum represents the upper limit for memory. Memory
allocations cannot go above the maximum. In order to go above the maximum, the
maximum value needs to be changed.
