IBM Power S1124 9824-42A
IBM Model S1124 9824-42A is the 4U Power11 scale-out system with P20 or P30 IBM i tiers, up to 8 TB of memory, and twice the internal NVMe bays of S1122.
Key Characteristics
- 16 through 60 Power11 cores
- P20 or P30 IBM i software tier
- 64 GB through 8 TB of DDR5 memory
- 16 internal NVMe bays and up to two NED24 drawers
- Supports AIX, IBM i, and Linux
Workload Fit
- Larger IBM i production systems
- Growth beyond S1122 memory and I/O limits
- Multi-workload consolidation
- P20 and P30 Power11 projects
IBM Model S1124 9824-42A is the largest scale-out system in the Power11 S-series. It is the model to compare when an S1122 quote looks workable today but too tight for the planned life of the system.
The 4U chassis supports 16 through 60 Power11 cores, P20 or P30 IBM i software tiers, up to 8 TB of memory, 16 internal NVMe bays, and two I/O expansion drawers. That is a real capacity step, not merely a taller version of S1122.
S1124 processor choices and IBM i tiers
3.4 to 4.2 GHz in IBM i tier P20.
3.05 to 4.15 GHz in IBM i tier P30.
2.8 to 3.95 GHz in IBM i tier P30.
The tier change matters before the benchmark number does. A 16-core or 32-core EP3X build stays in P20. The EP3H and EP3Y builds move to P30. That software tier belongs in the first quote comparison because it changes the cost of the system around the hardware.
S1124 memory, NVMe, and I/O capacity
32 DDR5 DDIM slots and twice the S1122 ceiling.
Up to 244.8 TB with 15.3 TB mainstream drives.
24 U.2 bays in each drawer.
Gen4 and Gen5 slot types.
Broader enterprise I/O while remaining in the S-series.
S1122, S1124, or E1150
S1122 9824-22A
2U Power11 with P10 IBM i, up to 4 TB, one NED24 drawer, and one I/O drawer.
S1124 9824-42A
P20 or P30 IBM i with up to 8 TB, 16 internal NVMe bays, and two drawers.
E1150 9043-MRU
Enterprise memory, database, or I/O capacity for AIX and Linux only. IBM i is not supported.
S1124 is the end of the scale-out comparison, not a smaller E1150. The right next model depends on the operating system as much as the capacity.
Source context: Midland's current S1124 9824-42A product record supplies the processor codes plus the P20 and P30 tiers. It also supplies the memory, NVMe, and I/O limits on this page. Confirm the final feature codes and partition plan in the quote.
