From the author of the vSphere Clustering Deep Dive series -
The VMware vSphere 6.5 Host Resources Deep Dive is a guide to building consistent high-performing ESXi hosts. A book that people cant put down. Written for administrators, architects, consultants, aspiring VCDX-es and people eager to learn more about the elements that control the behavior of CPU, memory, storage and network resources.
This book shows that we can fundamentally and materially improve the systems were building. We can make the currently running ones consistently faster by deeply understanding and optimizing our systems.
The reality is that specifics of the infrastructure matter. Details matter. Especially for distributed platforms which abstract resource layers, such as NSX and vSAN. Knowing your systems inside and out is the only way to be sure youve properly handled those details. Its about having a passion for these details. Its about loving the systems we build. Its about understanding them end-to-end.
This book explains the concepts and mechanisms behind the physical resource components and the VMkernel resource schedulers, which enables you to:
- Optimize your workload for current and future Non-Uniform Memory Access (NUMA) systems.
- Discover how vSphere Balanced Power Management takes advantage of the CPU Turbo Boost functionality, and why High Performance does not.
- How the 3-DIMMs per Channel configuration results in a 10-20% performance drop.
- How TLB works and why it is bad to disable large pages in virtualized environments.
- Why 3D XPoint is perfect for the vSAN caching tier.
- What queues are and where they live inside the end-to-end storage data paths.
- Tune VMkernel components to optimize performance for VXLAN network traffic and NFV environments.
- Why Intel's Data Plane Development Kit significantly boosts packet processing performance.

This book redefined the phrase “deep dive”, and I’m taking a lot of notes for future authoring and presentations. The depth of content is unparalleled in tech authoring.
Topic sections such as CPU, memory, storage, and networking, the four main areas of resource management on any virtualization host, are presented. Anyone can talk about these settings in general, but the advanced VCDX-level topics are covered in incredible depth. We work with a lot of advanced virtualized SQL Server VMs, and significant discussions from this book for performance tuning these SQL Servers include:
Advanced vNUMA balancing and optimization
CPU core counts versus clock speed
vNUMA memory speeds and non-local memory access
Clearing up misconceptions about vSphere Balanced Power Management
Queues and resource allocations
Go get this book – NOW! It’s a must read, and read it twice. No, three times. Then give the book to colleagues who can benefit. I’ve got two copies on my desk right now, and know who these will be sent to after I’m done re-reading them!
Clear, concise and to the point. This is a book I'll return to time and time again, as there is simply no way you can read this once, and be done with it. There is simply to much information in here to digest in a single read through. Don't be fooled by the VMware vSphere mention in the title, even if you don't work exclusively with VMware vSphere environments, this book is still an invaluable resource for anyone working with datacenter technologies.
Simply put: Buy this book.
