You are right. I'm not working myself on these systems but they are often still called with their older name here due to the frequent renaming... Regarding the processor: yes the processor spare is new to the Power11 but features like "Processor Instruction Retry" and "Alternative processor recovery" are older. Here are documents describing the feature for old 8284-22A (S822 with Power8 CPU) [1] or even older 8204-E8A (System Power 550 with Power6 CPU) [2] [1] https://www.redbooks.ibm.com/redpapers/pdfs/redp5098.pdf https://www.redbooks.ibm.com/redpapers/pdfs/redp5098.pdf (topic 4.3.4 and 4.3.5) [2] https://www.redbooks.ibm.com/redpapers/pdfs/redp4404.pdf https://www.redbooks.ibm.com/redpapers/pdfs/redp4404.pdf
