IBM Power 11 Models

IBM Power S1122 9824-22A

IBM Model S1122 9824-22A is the 2U Power11 choice for buyers who need more IBM i, AIX, or Linux capacity than S1112 without moving to a 4U system.

IBM Model S1122 9824-22A
Form Factor 2U scale-out
Family Scale-out
Supported Operating Systems AIX, IBM i, Linux
Best Fit IBM i, AIX, and Linux workloads that need a full-width 2U system with more capacity than S1112

Key Characteristics

  • 4 through 60 Power11 cores
  • P10 IBM i software tier
  • 64 GB through 4 TB of DDR5 memory
  • 8 internal NVMe bays and one optional NED24 drawer
  • Supports AIX, IBM i, and Linux

Workload Fit

  • 2U IBM i production systems
  • Growth beyond S1112 limits
  • Mixed AIX, IBM i, and Linux consolidation
  • Projects that do not need the 4U S1124 capacity envelope

IBM Model S1122 9824-22A is the Power11 model to compare when S1112 is too tight but a 4U S1124 is more system than the project needs.

It keeps the rack footprint at 2U while adding processor choices from 4 through 60 cores, up to 4 TB of memory, 8 internal NVMe bays, and more I/O expansion. The important catch is IBM i sizing: every S1122 is in software tier P10, but not every processor choice gives IBM i the same LPAR room.

S1122 processor choices and IBM i limits

ERGR eSCM

4 or 8 cores at 3.6 to 4.0 GHz. Midland lists 118,200 CPW for 4 cores and 236,400 CPW for 8.

ERGQ eSCM

10 or 20 cores at 3.05 to 4.0 GHz. AIX and Linux can use the wider system while IBM i follows the LPAR rule.

EBG8 DCM

16 or 32 cores at 3.0 to 4.2 GHz. More hardware cores do not automatically create a larger IBM i partition.

EBG9 DCM

24 or 48 cores at 2.65 to 4.15 GHz. Best suited when several partitions use the wider system.

EBGA DCM

30 or 60 cores at 2.4 to 3.95 GHz. Match the highest core counts to the complete partition plan.

Midland's current S1122 table lists a maximum IBM i LPAR size of 4 cores or 118,200 CPW, except for ERGR processor builds. That exception is the part a quote needs to state clearly. An 8-core ERGR configuration and a larger DCM configuration may have very different total resources while still producing a different IBM i answer than the hardware core count suggests.

S1122 memory, NVMe, and I/O capacity

Memory64 GB through 4 TB

32 DDR5 DDIM slots.

Internal NVMe8 U.2 bays

Up to 122.4 TB with 15.3 TB mainstream drives.

NED24 expansion1 drawer

24 U.2 bays beyond the chassis.

CEC PCIe10 adapter positions

Gen4 and Gen5 slot types.

I/O drawer1 drawer

12 Gen4 PCIe slots.

S1112, S1122, or S1124

S1112 9242-21B

Compact entry system. Move up when memory, storage, adapters, or IBM i growth exceed the smaller box.

S1122 9824-22A

2U P10 system with broader processor, memory, and I/O choices.

S1124 9824-42A

Largest S-series capacity with a higher IBM i tier, 8 TB, 16 internal NVMe bays, or two expansion drawers.

Source context: Midland's current S1122 9824-22A product record supplies the processor codes plus the IBM i tier and LPAR boundary. It also supplies the memory, NVMe, and I/O limits on this page. Confirm the final feature codes and partition plan in the quote.
