The argument around %CPU is mainly license cost. For example if
you have an Oracle license for that CPU, consuming any % of its
cycles costs you that fraction of the Oracle license in effect.
This is the argument that FC vendors, for example, use against
software based iSCSI and justify the cost of the HBA over a NIC.
Sounds exactly like a use case for Fair Share Scheduling and running
Oracle in its own processor pool and in a Zone. That way you get to pay
for a small number of CPUs in your Oracle license and you get to use
them for other things on the host.
