Used and Refurbished Power 9 Buying Rules
How to avoid buying the wrong Power 9 system, part, or maintenance problem in a mature reseller market.
The Practical Reading
Power 9 is mature infrastructure. That is not automatically bad. It simply means each decision should be tied to lifecycle, support, capacity, and migration timing rather than nostalgia or panic.
Checklist
Identify
Record machine type, serial, processor feature, memory, storage, adapters, and OS levels.
Validate
Check IBM support, reseller availability, firmware, and IBM i release fit.
Compare
Price maintenance and parts against a Power 10 or Power 11 replacement path.
Schedule
Put a real date on the next action, even when the answer is to keep the system.
