# ZAC using BPCii on IBM z15 and z16 - Report Tests 2022-10

#### Context

- Zetaly Automated Capacity (ZAC) is a widely used product to control and optimize IBM Z capabilities
- One of the main usage of ZAC is to dynamically control Defined Capacity, and optimize the LPAR DC depending on       the incoming workload, and the given set of CPU ressources
- To adjust the LPAR attributes, ZAC uses the BCPii interface to communicate with the underlying IBM Z

#### Scope

- The test scenario will be focused on Defined Capacity for the LPAR, using ZAC  
     - as it is the most common usage scenario for clients
- ZAC is using only BCPii API v1 (non rest)
- ZAC will be installed and configured on 3 LPAR, on a single CPC

#### Objectives

- Measure BCPii performance improvement between IBM z15 and z16
