We are thinking about HiperDispatch implementation but I am not sure it is appropriate in our environment. We have a z196 Host = 2817-M66/700 with 12 CPs. There is one large LPAR with a share that allows access to 8.89 CPs. It is assigned 12 LPs. The rest of the LPARs on this box have very low shares. There are 8 additional LPARs and the highest physical processor share is 1.05. The rest of the PP shares vary from 0.16 to 0.53. I am not sure that there is any point to turning on Hiperdispatch for these LPARs. I read an article by Don Deese where he said HiperDispatch Management Mode cannot be effective in an LPAR unless the LPAR has a share of CPC capacity that results in at least 0.5 (the #CP value) equivalent physical processors. This was in a document about the z10 and I am wondering whether it is also true on a z196. If we enable HiperDispatch on the one LPAR will there be a negative effect on the other LPARs? In total now there are 37 LPs assigned for the box. I think this is a high number. Any comments would be appreciated.
