Nesting partitions
gWLM allows you to form SRDs consisting of various compartment types. This ability provides
flexibility in dividing your complex. For example, you can divide your complex as shown in
Figure 5-1. The complex has four nPars, two of which are divided into vPars. One npar is hosting
virtual machines, and the fourth npar is not divided. gWLM allows you to create an SRD
containing the two virtual machine guests, the two vPars from npar 2, the two vPars from npar
3, and npar 4. The workloads in any of these compartments can then borrow resources from any
of the other compartments in the SRD. If TiCAP is available on the complex, gWLM can migrate
the usage rights to where they are needed.
NOTE: No more than one deployed SRD per complex should have nested partitions.
