- At the time IBM submitted its certification request for the IBM Power System E980 (9080-M9S), the Red Hat Enterprise Linux 8 (RHEL 8) supported limits for ppc64le-based systems were 768 logical CPUs and 32TB of memory, as stated here: Red Hat Enterprise Linux technology capabilities and limits.
As the IBM system can be configured with memory and processor amounts in excess of the supported RHEL 8 limits, it was subjected to extended testing beyond the normal hardware certification tests to achieve certification with configurations that exceed the supported limits.
