Lpar Memory Configuration – Guidelines for MaxMem

Guidelines for MaxMem

  • Don’t set MaxMem equal to total amount of server memory for each LPAR. This will waste memory with oversized HPTs.
  • Size MaxMem approximately 25 percent larger than Desired Memory for production LPARs that might require a DLPAR memory addition. For less important LPARs, which could be shutdown for a desired memory increase, set the MaxMem as close as possible to the Desired Memory.
  • Always set the MaxMem to a power of two to maximize DLPAR growth options.
