Lenovo Integration Management Module Standard Upgrade

Integrated Management Module II (IMM2) is the second-generation management module integrated on System x servers. IMM2 will offer three levels of functionality: Basic, Standard, and Premium. Starting with IMM2, the Virtual Media Key will no longer be used. Upgrading to Standard or Advanced will be performed using a software license key using a procedure named IBM Feature on Demand (FoD).
