Our VM LPAR is running with 2 dedicated IFLs. I know IFLs are supposed to
run at full speed, but the VELOCITY report ESAHDR (from ESAMAP 3.5.1)
shows:
Power of processor in terms of service Units: 8084
which equates to 50 MSU's -- the speed of the CPs (used by zOS) on our
z/890 (capacity setting 250, 2 CPs & 2 IFLs). Is this a reporting error
or are the engines used by VM not really running at full speed and/or not
really IFLs?
A more complete extract from the ESAHDR report, which follows, almost
makes me think that the engines in use aren't IFLs even though the LPAR
image is defined at the HMC to use IFLs.
