A system administrator is asked to review a proposed configuration for a 64 core Power 780 server that will have four 12X PCIe I/O Drawers. The intent is to ensure that the configuration will support the ability to take any single enclosure (CEC) offline for maintenance without isolating any of the 12X PCIe I/O Drawers from an SPCN segment attached to an active Power 780 enclosure. What is the correct number of System Power Control Network (SPCN) cables required for maximum availability?
