S1124 EP3H 24-core IBM i capacity
CPW is the IBM i throughput rating to size against. Compare 649,800 with the CPW of the system you run today and leave room for growth.
| IBM i | Configuration |
|---|---|
| Maximum CPW | 649,800 |
| CPW per core | 27,075 (649,800 / 24 cores) |
| Software tier | P30 |
| I/O | Native, virtualized through Virtual I/O Server (VIOS), or a combination of both |
The S1124 does not limit IBM i to a small partition size. Allocate the 24 cores across your IBM i, AIX, Linux, and VIOS partitions to fit the workload.
No AIX rPerf rating is listed for this configuration. Ask for AIX sizing with your quote.
S1124 memory and storage
| Specification | Configuration |
|---|---|
| Memory (model range) | 64 GB to 8 TB across 32 DDR5 DDIMM slots |
| Internal bays | Sixteen U.2 NVMe bays |
| Mainstream NVMe maximum | 244.8 TB raw, sixteen 15.3 TB modules |
| Enterprise NVMe maximum | 102.4 TB raw, sixteen 6.4 TB modules |
| NVMe expansion | Up to two NED24 drawers with 24 U.2 bays each |
Storage maxima are raw capacity, not usable capacity after mirroring or other protection. We confirm the memory slots available to a one-socket configuration with your quote.
S1124 EP3H 24-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 |
| Width x depth x height | 18.97 x 28 x 6.8 in. (482 x 712 x 173 mm) |
| 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. |
| Linux | RHEL 8.10, RHEL 9.4, or RHEL 10.0 or later; RHEL for SAP 9.6 or later; SLES 15 SP6 or later, including SLES for SAP. |
| Red Hat OpenShift | Container Platform 4.19 or later. |
| Hardware Management Console | HMC v11 using 7063-CR2 or virtual HMC. 7063-CR1 does not support Power 11 management. |
S1124 warranty and support options
| Coverage | Response objectives |
|---|---|
| Base warranty | Three years parts and labor, 9x5 next-business-day response. |
| Power Expert Care Advanced | 24x7 hardware coverage. Two-hour initial contact objective for Severity 1 and 2; onsite objective same day for Severity 1 and next day for Severity 2. Software maintenance with a two-hour Severity 1 response goal. |
| Power Expert Care Premium | 24x7 hardware coverage. Thirty-minute initial contact objective for Severity 1 and 2; four-hour onsite objective for Severity 1 and 2. Enhanced software maintenance with a thirty-minute Severity 1 and 2 contact objective. |
These are target objectives. Committed fix times for Severity 1 and 2 are an extra-cost option in eligible locations.
Compare S1124 EP3H 24-core with other S1124 configurations
EP3H 24-core gives 50 percent more CPW than EP3X 16-core and moves IBM i from P20 to P30. EP3Y 30-core stays in P30 and reaches 812,250 CPW from one socket. The two-socket EP3X 32-core reaches 823,000 CPW and stays in P20.
