Each application and service that is running on a cluster has specific CPU needs. Table 3–4 lists the CPU control activities that are available on different versions of the Solaris OS.

If you want to apply CPU shares, you must specify the Fair Share Scheduler (FFS) as the default scheduler in the cluster.
Controlling the CPU that is assigned to a resource group in a dedicated processor set in a global-cluster non-voting node offers the strictest level of control. If you reserve CPU for a resource group, this CPU is not available to other resource groups.
