One of the best virtualization related book of 2017, in my opinion, is the VMware vSphere 6.5 Host Resources Deep Dive written by Frank Denneman and Niels Hagoort.

It’s main target is 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. But the most valuable part, is that is not only update to vSphere 6.5, but also with new technologies, like new Xeon family, new type of disks, NVMe, …

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.

During the last VMworld 2017 (both US and EU edition), was also possible get a free copy signed by the author, thanks toRubriks that decided to support the community by giving away 2000 free copies of the printed version.

Now with the support both of Rubrik and the VMUG organization is it possible to have a Free e-book edition (PDF only)!
