Figure 2-12 Example of initial licensing planning 2.7.5 Sub-capacity licensing for IBM software Sub-capacity licensing allows for the licensing of a software program for use on less than the full processor capacity of the System p5 systems when the software program is used within two or more partitions. Sub-capacity licensing allows a client to benefit from hardware partitioning that includes advanced IBM virtualization capabilities, such as shared processor pools, Micro-Partitioning (allowing for processor license sharing), and dynamic reallocation of resources with flexible software licensing support. The following are important considerations for sub-capacity licensing of IBM software: ► ► ► ► The sub-capacity licensing program applies to selected IBM Passport Advantage programs licensed on a per-processor basis. The client agrees to the terms of an attachment to their International Passport Advantage Agreement and submits a Passport Advantage Enrollment Form to IBM or Business Partner. The client must use IBM Tivoli License Manager for IBM Software to monitor program use and submit to IBM an IBM a use report each calendar quarter. At the time of this writing, System p5 software is not required to be monitored by ITLM. 62 <strong>Advanced</strong> <strong>POWER</strong> <strong>Virtualization</strong> on IBM System p5
IBM Tivoli License Manager (ITLM) allows the program to monitor the use of processor licenses in all the partitions where the monitored IBM software program is installed (partitions with dedicated processors, and capped and uncapped micro-partitions). For the partitions in the System p5 server where it is installed, ITLM monitors the overall usage of processor licenses, detects changes in system configuration from dynamic LPAR operations and CUoD and CUoD On/Off processor activations, and notifies IBM periodically about such changes and differences in licensing. Since IBM software program licenses are incremental, the client is required to purchase additional IBM software licenses when the use has exceeded the overall entitlement license capacity (Figure 2-13). For capped micro-partitions, ITLM becomes the tool that constantly measures the entitlement capacity of the operating systems and allows you to match the initial licensing provisioning versus the real consumption in the shared processing pool.
