IBM Power S1124 9824-42A
IBM Model S1124 9824-42A is the larger 4U scale-out Power11 server for heavier consolidation and growth beyond S1122.
Key Characteristics
- 4U rack form factor
- Higher core and memory ceiling than the S1122
- Supports AIX, IBM i, and Linux
Workload Fit
- Growing IBM i and AIX environments outgrowing a 2U system
- Multi-workload consolidation
- Mid-market to lower-enterprise scale-out deployments
IBM Model S1124 9824-42A is the larger 4U scale-out Power11 rack system in the lineup, positioned above the S1122 9824-22A for organizations that need more core and memory headroom or that are consolidating multiple smaller workloads onto one system.
It runs the same AIX, IBM i, and Linux operating systems as the S1122, but the 9824-42A model changes the conversation from compact 2U growth into broader 4U production scale-out.
What IBM Model S1124 9824-42A changes
| Area | S1124 9824-42A position | Buyer impact |
|---|---|---|
| Chassis stance | 4U scale-out | Gives the system more room for larger growth and I/O planning than the 2U scale-out boxes. |
| Family role | Largest S-series scale-out IBM i, AIX, and Linux model | Often the last stop before a buyer shifts from scale-out thinking into enterprise E-series thinking. |
| Best-fit projects | Mixed-workload growth, broader consolidation, larger IBM i estates | Useful when several smaller workloads need to land on one platform with room to grow. |
| Comparison trigger | Quote beside E1150 when database or resilience requirements become more enterprise-like | Keeps buyers from defaulting to 4U scale-out when the real need is enterprise-class behavior. |
Why buyers choose S1124 instead of S1122
The S1124 9824-42A becomes the right answer when the S1122 9824-22A looks serviceable today but too tight for the service life of the platform. Buyers usually get here because of projected partition growth, broader consolidation goals, or storage and adapter planning that already wants more breathing room than a denser 2U platform offers.
It is still a scale-out machine, but it is the scale-out machine for buyers who already know their footprint will not stay small.
