Power 9 vs Power 11
Power 9 reached end of life. Power 11 is the current replacement generation for owners who need a supported system and a longer runway.
Power 9 reached end of life. Power 11 is the current replacement generation, with IBM i 7.6 support on the right models and a new warranty, support, firmware, and capacity runway.
The upgrade is not a one-for-one model-name swap. Size it from the workload the business runs now and the growth it expects next.
Start with the Power 9 machine type
Use the Power 9 model directory to identify the installed server and processor. Then use the comparison below to choose the Power 11 family that belongs in the quote.
Build the upgrade quote from the workload
Have providers price the Power 11 replacement against the same peak workload, software, storage, I/O, downtime, and support needs. Compare providers in the IBM reseller directory or request an IBM Power quote.
Power 9 to Power 11 upgrade comparison
| Decision Area | Power 9 Reality | Power 11 Move | Buyer Meaning |
|---|---|---|---|
| Lifecycle | Power 9 reached end of life and remains installed in working businesses. | Power 11 is the current replacement generation. | Plan the move before support or an outage sets the deadline. |
| IBM i release | IBM i 7.5 is the ceiling on selected Power 9 systems. IBM i 7.6 is not supported. | Power 11 supports current IBM i planning on the right models. | IBM i 7.6 requires a hardware upgrade. |
| Entry replacement | S914 owners may have P05 or P10 software and very different CPW needs. | Compare S1112 and S1122. | Size from peak CPW, memory, storage, adapters, and growth. |
| Scale-out replacement | S922 and S924 cover P10 and P20 IBM i workloads plus AIX and Linux. | Compare S1122 and S1124. | Carry forward the real workload instead of the old core count alone. |
| Linux and SAP replacement | L922 and H-series systems need workload and certification checks. | Compare L1122 and L1124 with the current SAP-certified design. | Treat the HANA layout and cutover as part of the server choice. |
| Enterprise replacement | E950 supports AIX and Linux but not IBM i. E980 supports IBM i, AIX, and Linux. | Compare E1150 for E950 and E1180 for E980. | Keep the operating-system difference clear before sizing begins. |
Decision Notes
- Power 11 is the replacement generation. The exact model depends on the operating system and the workload, not the Power 9 name alone.
- A working Power 9 server still needs an upgrade date because support, firmware, parts, and IBM i release limits can narrow the choices.
- A useful quote starts with the machine type, processor feature, memory, storage, adapters, operating-system level, peak workload, and downtime window.
