Abstract

Methods and apparatus relating to optimizing boot-time peak power consumption for server and/or rack systems are described. In an embodiment, a module execution sequence for a computing device is determined to indicate a sequence of module execution during a boot process of the computing device. The module execution sequence is determined based at least partially on power consumption data and timeline data for each module of the computing device during the boot process of the computing device. Other embodiments are also claimed and described.
