HiperDispatch has been around for a number of years now, but there is still a
misunderstanding of the true differentials and effectiveness of logical
processors designated as high, medium, and low. In addition, there is the
seemingly never ending questions of how HiperDispatch determines the number of
high, medium, and low pool processors for an LPAR. A common practice is to
optimize LPAR configuration such that the most important LPARs have at least one
high pool processor. But how much does this matter in real life? How much
benefit can you expect to gain for your most-loved LPARs if you can give them an
extra high-pool processor? How much might that hurt other LPARs? During this
session, Scott Chapman will dive deeper into HiperDispatch and help the
attendees better understand the true meaning and effectiveness of each pool of
processors. -- Presented by Scott Chapman
