In this chapter, you learned what the concepts of storage virtualization are and how to monitor storage metrics using vSphere performance charts and esxtop/resxtop. We also covered management of vSphere storage using the command line. Then you looked at a list of some scenarios that describe existing performance problems, and provided solutions for those performance problems. We also saw what VMware's recommended configuration for the storage array and vSphere hosts is, according to the best practices.
In the next chapter, we will see how to find the location of VMware ESXi and vCenter, and identify the log used to troubleshoot storage performance problems.
