Top 10 things you must read to get more technical with VI3
Once you have learned the basics of Vmware VI3 it's time to dig deeper into it and learn even more about it to get more detailed information on how everything works. There are many unique concepts in virtualization that vastly differ from traditional physical servers that you need to understand to become an expert with it. If you want to go beyond the basics then you need to learn more about things like memory usage, performance, resource management, cpu scheduling, SAN configuration and security. This top 10 list is a combination of white papers and documentation from VMware as well as VMworld 2007 presentations that will help you increase your knowledge to help you master VMware VI3.
