S1022 EPGA 20-core IBM i capacity
| IBM i | Configuration |
|---|---|
| CPW per IBM i LPAR | 106,300 |
| Software tier | P10 |
| Cores per IBM i LPAR | 4 |
| I/O | Virtualized through VIOS; multiple IBM i partitions supported |
The 20 physical cores describe the system, not one IBM i partition. Allocate them across your IBM i, AIX, Linux, and VIOS partitions.
S1022 EPGA 20-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 20-core | Four cores per IBM i LPAR | 106,300 | 26,575 |
S1022 EPGA 20-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.
No AIX rPerf rating is listed for this one-socket configuration. The two-socket EPGA 40-core is rated 1024.1 at SMT8.
