Abstract

A qualitative resource assignment wizard receives qualitative information for a logical partition (LPAR) and calculates computer resource assignments for the LPAR based on the qualitative information and a set of conversion functions. For example, the qualitative resource assignment wizard may calculate a processing unit assignment, a memory assignment, and an I/O slot assignment for the LPAR. The qualitative information may be input by a user, for example, utilizing a graphical user interface (GUI). In one embodiment, the conversion functions are calculated during a training phase, in which a user periodically provides qualitative information while resource usage data is gathered. The wizard may reside in a hardware management console (HMC) or other administrative console and/or may be a component of a hypervisor or other partition management code. Software code associated with the wizard may be provided by a network server application to a client system for enabling a user to remotely input the qualitative information.
