For a book titled “Master VMware vSphere Storage,” about 1/3 of the book is spent discussing other topics. Storage does not get directly discussed until 88 pages in and begins by discussing storage APIs. I can understand giving a brief overview of vSphere but a majority of the review should be focused on the storage protocols and storage architecture rather than beginning with storage APIs and storage profiles. Once the book finally delves into configuring, optimizing, and troubleshooting storage, it does a good job covering the topics…though out of order at times (i.e. discusses optimizing before how to configure storage). Many great screenshots and diagrams demonstrating the points of discussion. However, for a book written for vSphere 5.1 / 5.5, there are quite a few screenshots from the vSphere Client rather than the vSphere Web Client. Overall 3/5.
