My company wants to downgrade its processor, but it recognizes that there may be significant processing constraint if they do. So they want to simulate the environment before they take the plunge.
The environment is a 3 engined 552 MIPS CEC, and the goal is to downsize to a 492 MIPS CEC. The Company runs 6 LPARs on this processor. My thinking is that I may be able to simulate the 492 MIPS processor using the following technique: 1. Define a test LPAR to a weight equivalent to 60 MIPS (approximately 10.87% of the processor) and hard cap it on the HMC, then 2. Initiate two IEFBR15 soaker jobs to drive the capped test LPAR to 60 MIPS and keep it there till the Company obtains the performance observations it requires. Once the test is completed, the hard cap can be removed from the test LPAR and test LPAR can be returned to its former weight. This seems straight forward.
