The utilization and performance of SAN storage can affect the performance of every virtual machine in the virtualization environment. The vSphere administrator should know how to monitor the host's storage IOPS and troubleshoot performance using vSphere tools and the command line. They should also know the property of SAN storage and operation flow between the vSphere host and SAN storage. Then they can solve performance problems easily.
In this chapter, we will learn:
Concepts of storage virtualization
Monitoring vSphere storage
vSphere storage management using the command line
Troubleshooting vSphere storage performance problems
