Summary: comparing FCP and ECKD disk devices

Taking into account the aspects summarized in the executive summary above, some clear recommendations can be made as to which device configuration is most suitable:
  • When maximum performance should be reached FCP devices are good candidates, but it requires additional CPU capacity to drive the workload
  • When administration effort and low CPU requirements have a high priority, ECKD devices with HyperPAV are good candidates

There are certainly other criteria such as the existing environment and skills which might favor one or the other disk type.
