Q: What is the most important aspect of deploying ESX Server and virtual machines?
A: The ability to provide service at least as good as that which you had with physical servers. With adherence to best practices, you should easily be able to provide this and exceed it by a phenomenal degree.
Q: ISOs have been mentioned in several of the chapters. Why are they so important?
A: Good administrators strive to never leave their chairs, cubes, or offices. If they do, they may just run into a user (we're kidding, of course). Having a library of ISOs can help you in this endeavor. In addition, they run a lot faster than regular CDs.
Q: What will happen if I deploy systems management software on the ESX Server itself?
A: If you're going to do this, make sure you allocate enough memory so that the application doesn't impact the performance of your ESX Server and thus your virtual machines. Also, use a system management package that is supported and test your installation on your ESX Server thoroughly. If you notice a degradation of performance, contact the systems management software vendor. The major vendors have instructions and best practices for deploying their products onto ESX Server.
Q: What is the most important best practice to follow?
A: The one that ensures your smooth evolution into a virtual infrastructureeducation. Learn every aspect of a virtual environment to the best of your ability. Be passionate about it and you'll reap the rewards. See the recommended reading list, troll the VMware Web site regularly, as well as other Web sites dedicated to virtualization such as p2v.net, vmguru.com, and virtual-strategy.com.
