Mastering VMware vSphere Storage

By: Victor Wu, Eagle Huang

Overview of this book

<p>vSphere Storage is one of the three main infrastructure components of a vSphere deployment (Compute, Storage, and Network).</p> <p>Mastering VMware vSphere Storage begins with an insightful introduction to virtualization and creating your own virtual machines. We then talk about VMware vCenter Server and virtual machine management, as well as managing vSphere 5 using vSphere Management Assistant (vMA) and esxcli and vmware-cmd commands. We then swiftly move on to a very interesting topic, reviewing the vSphere performance and troubleshooting methodology. We then configure VM storage profiles, Storage DRS, and Storage I/O control. More significantly, we will troubleshoot and analyze storage using the VMware CLI and learn how to configure iSCSI storage.</p> <p>By the end of the book, you will be able to identify useful information to make virtual machine and virtual data center design decisions.</p>

vSphere 5 storage maximums


In some cases, the vSphere administrator isn't aware of the maximum configuration or limitations of the vSphere storage, for example, the maximum volume size of VMFS volume, or number of targets per HBA adapter. It gives some configuration errors during vSphere storage configuration. It has a different maximum configuration and limitation in each edition of vSphere. The following table shows the common maximum configuration settings in a vSphere 5.1 host:
