An IBM I customer has installed a Power System E980 with 32 installed and 20 active cores. They run VIOS on four cores and three IBM i LPARS in capped mode.
LPAR A uses 8 cores.
LPAR B uses 6 cores.
LPAR C uses 2 cores.
The customer has a requirement to make LPARs A and B highly available and wants to use PowerHA for IBM i to achieve this.
What is the minimum number of cores that need to be licensed for PowerHA on the primary server?
