Nested 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 1-2 “Nested partitions”. 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 Temporary Instant Capacity is available on the complex, gWLM can migrate the usage rights to where they are needed.
