i5/OS on IBM System p5 and eServer p5 servers

This topic provides information about some limitations and constraints that exist for i5/OS^® on an IBM System p5™ and eServer™ p5.

You can choose to install and run i5/OS on an IBM System p5 and eServer p5 server if all of the following conditions apply:

• You have a limited amount of i5/OS workload.
• You anticipate limited growth for your i5/OS workload.
• You want to consolidate your i5/OS workload onto a single server where the processing capability on the server will be almost entirely used by either AIX^® or Linux^® logical partitions.

There are limitations to how you can configure your i5/OS logical partitions on an IBM System p5 and eServer p5 server, and you cannot upgrade the IBM System p5 and eServer p5 server to overcome these limitations. IBM System i5™ and eServer i5 servers are more suitable for users who want to upgrade their current iSeries™ servers and who anticipate continued i5/OS application workload growth. You might also consider IBM System i5 and eServer i5 servers if you want to use your iSeries skills to manage the consolidated environment.

• Requirements for i5/OS on IBM System p5 and eServer p5 servers
  All of the hardware requirements for running i5/OS on IBM System i5 and eServer i5 servers also apply to running i5/OS on IBM System p5 and eServer p5 servers. In addition, you must also adhere to the hardware requirements specific to running i5/OS on an IBM System p5 and eServer p5 server.
• Limitations for running i5/OS on IBM System p5 and eServer p5 servers
  There are several limitations for running i5/OS on IBM System p5 and eServer p5 servers. They include limitations to server models, processors, and using resources of other logical partitions.
• Supported functions
  Although there are limitations to how you can implement i5/OS on IBM System p5 and eServer p5 servers, many functions are still available.
• Migration process
  Before you begin, you must ensure that you have met all the requirements required to run i5/OS on IBM System p5 and eServer p5 servers. Otherwise, the hardware and software installation processes are identical to those used to install i5/OS on IBM System i5 and eServer i5 servers.
