zIIPs

Software pricing implications Furthermore, from a software perspective, zIIPs are very similar in concept to zAAPs. zIIPs cannot be IPL'd and cannot run any operating systems. This optional feature allows customers to purchase additional processing power exclusively for select data serving environments without affecting the total MSU rating or machine model designation. IBM does not impose IBM software charges on zIIP capacity. Additional IBM software charges apply when additional general purpose CP capacity is used. Also, zIIPs may have the effect of reducing charges for Sub-capacity eligible IBM software products by lowering the rolling 4-hour average MSUs for LPARs with assigned zIIPs. Customers are encouraged to contact their specific ISVs/USVs directly to determine if their charges will be affected.
