S1124 EP3H 48-core IBM i capacity
CPW is the IBM i throughput rating to size against. Compare 1,118,500 with the CPW of the system you run today and leave room for growth.
| IBM i | Configuration |
|---|---|
| Maximum CPW | 1,118,500 |
| CPW per core | 23,302 (1,118,500 / 48 cores) |
| Software tier | P30 |
| I/O | Native, virtualized through Virtual I/O Server (VIOS), or a combination of both |
This configuration's description lists 649,800 CPW, the same figure as the one-socket EP3H 24-core. Our processor options list gives 1,118,500 CPW for 48 cores. We confirm the rating with your quote.
The S1124 does not limit IBM i to a small partition size. Allocate the 48 cores across your IBM i, AIX, Linux, and VIOS partitions to fit the workload.

S1124 EP3H 48-core I/O, power, and physical specifications
| Specification | Configuration |
|---|---|
| Chassis | 4U rack |
| Processor-dependent PCIe | Gen5 operation with DCM; slot-specific qualifications below |
| CEC slot topology | Four Gen4 x16 or four Gen5 x8 slots; four Gen5 x8 slots with x16 connectors; two Gen4 x8 slots with x16 connectors |
| PCIe expansion | Up to two Gen4 I/O drawers; we confirm the drawer and slot arrangement with the configuration |
| Power supplies | Up to four EB3S 1600 W Titanium AC supplies, 200 to 240 V |
| Maximum power draw | 2,750 W; 2.835 kVA; single phase |

| Weight | 96 lb (43.54 kg) |
Power supplies must be ordered with the system and cannot be added later. Choose the supply count for redundancy before the order is placed.
With DCM, all PCIe slots are described as running at Gen5 speeds, while the slot list also includes Gen4 slots. We will confirm each adapter and slot speed with the selected configuration.
S1124 management, availability, and security
- Chipkill memory and active memory mirroring.
- Redundant hot-plug power and cooling, with hot-plug PCIe slots for concurrent maintenance.
- Spare processor cores that can take over from a failing core without restarting the system.
- eBMC management, processor instruction retry, and dynamic processor deallocation.
- PowerVM Enterprise Edition with optional dual VIOS.
- Capacity Upgrade on Demand (CUoD) and Power Private Cloud EP2.0.
- Up to 1,000 logical partitions or micro-partitions across the system.
- IBM 4770 Crypto Card option for quantum-safe protection, and IBM Power Cyber Vault offered with IBM Storage and IBM Expert Labs.
S1124 software and management requirements
Match the installed OS release to the selected processor feature. HMC v11 requires a 7063-CR2 appliance or virtual HMC; the 7063-CR1 cannot manage Power 11.
| Software | Levels |
|---|---|
| IBM i | 7.6 with Power 11 GA PTF group; 7.5 TR6 or later; 7.4 TR12 or later. Runs natively, virtualized, or both. |
| AIX with any I/O | 7.3 TL03 / SP 7300-03-01-2520; 7.2 TL05 / SP 7200-05-10-2520; or 7.3 TL02 / SP 7300-02-04-2520, or later. |
| AIX virtual-I/O-only partitions | 7.3 TL03 / SP 7300-03-00-2446; 7.3 TL02 / SP 7300-02-02-2420; or 7.2 TL05 / SP 7200-05-08-2420, or later. |
| VIOS | 4.1.1.10, 4.1.0.40, or 3.1.4.60, or later. |
