On non z/OS platform like x86 with Linux or Windows servers, we often use Dev or Test machines at a purposely less than 50% capacity allowing DR on the test machines as the remaining CPU power is available. Contrary to what a lot of people say about mainframe, using CPU's at a low percentage is a definite advantage as far as you are not paying a different bill,and using a CPU at 95% is just a disadvantage.
And, this is exactly what I'm seeing many of our customers doing with their mainframes. They are setting up LPAR Capacity groups to guarantee a large amount of so-called "white space" on the CEC--sometimes over 50 percent. They can then use this white space for sudden demand spikes from existing LPARs or for failover from other LPARs or CECs.
