Apparatus and method for specifying maximum interactive performance in a logical partition of a computer system independently from the maximum interactive performance in other partitions

摘要

A partitioner for creating logical partitions allows a user to specify maximum interactive performance in one partition independently of maximum interactive performance of other partitions to arrive at logical partitions that may be much different than the maximum overall interactive performance percentage of the computer system itself. First, the maximum interactive performance for a computer system is specified, and resources are allocated accordingly. Next, logical partitions may be created, which initially reflect the maximum interactive performance for the computer system as a whole. Finally, the maximum interactive performance can be specified for a partition independently of the interactive performance in other partitions. In this manner a computer system that is configured as a server system with low interactive and high batch performance can have two different partitions, one that has very low interactive performance and the other that balances interactive and batch processing. In this manner two partitions that have greatly different performance attributes can be defined within the limitations of the specified interactive and batch performance for the computer system as a whole.
