IBM Power E1150 (9043-MRU)
A 4U enterprise scale-up server built for memory- and data-intensive AIX and Linux workloads, offering up to 120 Power 11 cores and 16 TB of DDR5 memory per node. Does not support IBM i.
The 9043-MRU is the machine type of the IBM Power E1150, the four-socket 4U enterprise system in the Power 11 line. It scales to 120 cores and 16 TB of DDR5 per node with heavy I/O expansion behind it. There is one thing about this machine type that decides most enquiries immediately: it does not run IBM i.
The E1150 is an AIX and Linux machine. That is why it carries rPerf ratings rather than CPW and why it has no IBM i software tier. If you found this machine type while sizing an IBM i consolidation, the 9080-HEU E1180 is the enterprise Power 11 system you want, and the 9824-42A S1124 is the scale-out one.
The E1150 runs AIX and Linux only. It does not support IBM i. Enterprise-scale IBM i buyers should evaluate the E1180 or a scale-out S-series model (S1122/S1124) instead.

E1150 vs E1180
Choosing between E1150 and E1180
| Factor | E1150 | E1180 |
|---|---|---|
| Max cores (commonly quoted build) | 120 (4 sockets, single node) | 128 (8 sockets, 2 nodes) |
| Max cores (full scale) | 120 (single node only) | Up to 256 across a 4-node maximum configuration |
| IBM i support | Not supported (AIX/Linux only) | Supported |
| Max memory | 16 TB per node | Up to 64 TB across up to 4 nodes |
| Positioning | Mid-tier enterprise scale-up, AIX/Linux | Flagship, highest-end enterprise scale-up, IBM i/AIX/Linux |
All Power 11 servers, including the E1150, require a v11 Hardware Management Console: either the HMC 7063-CR2 hardware appliance or the IBM vHMC software appliance. The prior 7063-CR1 model is not supported.

Figures are the published maximums for this machine type. A specific installed system is defined by its processor feature code and activated core count, not by the machine type alone.
How to confirm you have a 9043-MRU
From IBM i
DSPSYSVAL QMODEL returns the model portion and DSPSYSVAL QPRCFEAT returns the processor feature code. Together those two values identify a 9043-MRU build exactly, which is more than the E1150 name alone tells a vendor.
From AIX, Linux or VIOS
lsconf reports the machine type and model on the first lines of output. prtconf gives the same alongside processor implementation and clock speed.
From the HMC
Managed system properties shows the machine type-model and serial together, plus installed against activated cores. This is the view to screenshot when requesting a quote.
From the bezel
The 9043 prefix is shared with the Power 10 E1050, which is 9043-MRX. The suffix is the only thing separating a Power 11 E1150 from a Power 10 E1050 in a parts lookup.
Next steps for a 9043-MRU
Processor features across the enterprise line are compared on the Power 11 CPU page, with the full listing at IBM Power E1150. For an IBM i enterprise workload, see the 9080-HEU E1180 instead, and check the ceilings on the Power 11 specs page.
