S1022 EPGA 40-core IBM i capacity
| IBM i | Configuration |
|---|---|
| CPW per IBM i LPAR | 104,700 |
| Software tier | P10 |
| Cores per IBM i LPAR | 4 |
| I/O | Virtualized through VIOS; multiple IBM i partitions supported |
The 40 physical cores describe the system, not one IBM i partition. Allocate them across your IBM i, AIX, Linux, and VIOS partitions.
S1022 EPGA 40-core CPW per core
CPW per core is the CPW rating divided by the cores that deliver it. IBM i is licensed by core, so this number shows how much IBM i work you get from each licensed core. On this model each IBM i partition is limited to four cores, so the figure is the partition rating divided by four.
| Configuration | Cores counted | CPW | CPW per core |
|---|---|---|---|
| EPGA 40-core | Four cores per IBM i LPAR | 104,700 | 26,175 |
S1022 EPGA 40-core AIX performance (rPerf)
rPerf is the relative performance rating for AIX workloads. ST is single-thread. SMT2, SMT4, and SMT8 show the rating with two, four, or eight hardware threads running on each core.
| Configuration | ST | SMT2 | SMT4 | SMT8 |
|---|---|---|---|---|
| EPGA 40-core | 324.1 | 602.4 | 798.4 | 1024.1 |

Compare S1022 EPGA 40-core with other S1022 configurations
Every S1022 runs IBM i in four-core partitions, so the choice between two-socket features comes down to core count and clock speed for AIX and Linux, and how many IBM i partitions you need.
