IBM System p POWER5 Model Map
Match every IBM p5 and System p POWER5 machine type to the model name people used, then carry the exact code into parts, support, operating system, and migration work.
The name on an old purchase order is not enough. Use the full machine type and model from the server label or IBM record because p5 520, 52A, 550, 55A, 570, 575, 590, and 595 are different planning records.
IBM System p POWER5 and POWER5+ machine types
Model names follow IBM's POWER5 system documentation.
| Machine type and model | IBM model | Original role | What to verify now |
|---|---|---|---|
| 7037-A50 | System p5 185 | Compact entry AIX and Linux | Processor option, memory, disks, operating system, and attached I/O |
| 9115-505 | System p5 505 | Entry rack server | Exact processor option, adapters, storage, and application support |
| 9110-510 | System p5 510 | Entry tower or rack server | Full machine code, processor feature, memory, and operating system |
| 9110-51A | System p5 510 | Updated entry configuration | Do not shorten 51A to 510 on parts or migration records |
| 9111-520 | System p5 520 | Entry and workgroup server | Processor generation, memory, storage, adapters, and partitions |
| 9131-52A | System p5 52A | POWER5+ entry system | Full 52A code, feature code, operating system, and activated capacity |
| 9113-550 | System p5 550 | Entry and midrange server | Processor count, memory, partitions, storage, and sustained work |
| 9133-55A | System p5 55A | POWER5+ entry and midrange | Full 55A code, processor feature, and current workload evidence |
| 9116-561 | System p5 560Q | Quad-core midrange server | Processor books, partitions, memory, I/O, and high-availability role |
| 9117-570 | System p5 570 | Modular midrange and enterprise | Every building block, partition, shared resource, and recovery dependency |
| 9118-575 | System p5 575 | High-performance computing | Cluster role, interconnect, storage, Linux or AIX level, and application support |
| 9119-590 | System p5 590 | Enterprise scale-up | Activated processors, partition map, I/O drawers, storage, and recovery design |
| 9119-595 | System p5 595 | Flagship enterprise scale-up | Complete partition, memory, I/O, storage, software, and recovery inventory |
A machine-type match identifies the family. It does not prove the processor feature, activated capacity, installed memory, storage, adapters, operating system level, or recovery condition.
Four things to capture after the model matches
1. Capacity
Record processor feature, processors installed, processors activated, memory installed, and real peak use.
2. Partitions
List every AIX or Linux partition, shared processor pool, virtual adapter, and VIOS dependency.
3. Connections
Record internal and external storage, tape, network, SAN, drawers, and special adapters.
4. Recovery
Prove backups can restore the operating system, application, data, security, and the connections around them.
If the label is hard to read, enter the partial code in the decoder and then confirm the result from AIX system commands, the HMC, or the IBM configuration record.
