Hardware requirements for logical partitions
To implement logical partitions successfully, you need to ensure your hardware resources meet the minimum requirements. Evaluate each iSeries™ model to determine how your hardware will function once you partition your server.
During the process of planning for logical partitions, decide how you want to configure hardware resources. You can configure each server with logical partitions differently based on the following topics.
- Determining the possible number of logical partitions
The number of processors you want to add to a logical partition depends on the planned workload for the partition and the desired level of performance.- Selecting bus-level or IOP-level partitioning
Depending on your needs, there can be advantages to partitioning your I/O resources in different ways.- Choosing dedicated or switchable IOP and devices for logical partitions
Although the recommended approach is to confine all hardware within a partition, this is not always a cost-effective solution. With some devices it might be preferable to share them among partitions.- Selecting dedicated or shared processors
Partitions can use one of two modes of processors on the iSeries server. The results of your capacity planning and system hardware configuration can help you decide to utilize dedicated processors or the shared processor pool for each partition.- Performing dynamic movement of resources
Dynamic movement of resources provides users the ability to move resources between partitions without requiring a partition or system restart.- Evaluating the hardware limitations of the iSeries servers
Not all models of iSeries server support logical partitions (LPAR). You need to evaluate the hardware situations of your system before implementing logical partitions.- Networking for logical partitions
Logical partitions can use any of several communication methods to interact with other partitions or servers.
