IBM Power S1122 9824-22A
IBM Model S1122 9824-22A is the mainstream 2U scale-out Power11 rack server for IBM i, AIX, and Linux growth beyond S1112 limits.
Key Characteristics
- Dense 2U rack form factor
- Up to 60 Power11 cores
- Up to 4 TB memory
- Supports AIX, IBM i, and Linux
Workload Fit
- Rack-based SMB and mid-market IBM i workloads
- Growth beyond S1112 memory and processor ceilings
- Mixed AIX/IBM i/Linux consolidation at modest scale
IBM Model S1122 9824-22A is the mainstream 2U scale-out Power11 rack model. Where the S1112 9242-21B focuses on entry IBM i, branch, and near-edge deployments, the S1122 9824-22A gives buyers a full-width 2U platform with materially more processor, memory, and I/O headroom.
That makes the S1122 9824-22A the cleaner fit when the S1112's 512 GB ceiling, 4 direct NVMe bays, or IBM i boundaries start to feel tight, but the workload still does not justify moving into the 4U S1124 9824-42A or enterprise E-series.
What IBM Model S1122 9824-22A is for
| Question | S1122 9824-22A answer | Why it matters |
|---|---|---|
| Primary role | Mainstream 2U scale-out IBM i, AIX, and Linux server | This is the model many buyers will land on when they want a modern rack server without jumping to 4U. |
| Scale position | Above S1112 and below S1124 | It is the midpoint where compact entry deployments turn into broader production growth plans. |
| Core and memory stance | Up to 60 Power11 cores and up to 4 TB memory | Enough room for materially larger partitions and longer growth runway than the S1112 class. |
| Typical buyer | IBM i, AIX, or mixed-workload shops that need real scale-out capacity in 2U | It catches many mid-market refresh projects before they become 4U or enterprise decisions. |
Why buyers step up from S1112 to S1122
The S1122 9824-22A is where the Power11 story starts to feel less like compact entry hardware and more like a long-lived production platform. If IBM i growth, memory appetite, or mixed partition density already looks larger than the S1112's compact design envelope, the S1122 is usually the more honest first quote.
It still preserves the 2U rack posture that many data centers want, but it stops forcing buyers to squeeze around the smaller platform assumptions of the S1112 class.
