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 can’t 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 we’re 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 you’ve properly handled those details. It’s about having a passion for these details. It’s about loving the systems we build. It’s 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.

商品描述(中文翻譯)

《VMware vSphere 6.5 主機資源深入解析》是一本建立一致高效的 ESXi 主機的指南,由《vSphere 集群深入解析系列》的作者撰寫。這是一本讓人無法放下的書。適合系統管理員、架構師、顧問、有志成為 VCDX 的人以及渴望深入了解控制 CPU、記憶體、儲存和網路資源行為的元素的人閱讀。

這本書展示了我們可以從根本上和實質上改善我們正在建立的系統。通過深入了解和優化我們的系統,我們可以使目前運行的系統保持一致的更快速度。

事實上,基礎架構的細節很重要。細節至關重要,尤其是對於抽象資源層的分散式平台,如 NSX 和 vSAN。只有深入了解您的系統,才能確保您正確處理了這些細節。這是對這些細節的熱情。這是對我們所建立的系統的熱愛。這是對全面了解它們的理解。

本書解釋了物理資源組件和 VMkernel 資源排程器背後的概念和機制,使您能夠:
- 為當前和未來的非一致性記憶體存取(NUMA)系統優化工作負載。
- 了解 vSphere 平衡電源管理如何利用 CPU Turbo Boost 功能,以及為什麼高性能模式不會使用該功能。
- 了解每通道 3-DIMMs 配置導致性能下降 10-20% 的原因。
- 了解 TLB 的工作原理,以及在虛擬化環境中禁用大頁面的壞處。
- 瞭解為什麼 3D XPoint 是 vSAN 快取層的理想選擇。
- 瞭解佇列是什麼,以及它們在端到端儲存數據路徑中的位置。
- 調整 VMkernel 組件以優化 VXLAN 網路流量和 NFV 環境的性能。
- 瞭解為什麼 Intel 的數據平面開發套件(DPDK)顯著提升了封包處理性能。

這本書將幫助您深入了解 vSphere 6.5 主機資源,並提供實用的優化建議,以提升您的系統性能。
