VMware vSphere 6.7 Data Center Design Cookbook - Third Edition

By: Mike Brown, Hersey Cartwright

Overview of this book

VMware is the industry leader in data center virtualization. The vSphere 6.x suite of products provides a robust and resilient platform to virtualize server and application workloads. This book uses proven infrastructure design principles and applies them to VMware vSphere 6.7 virtual data center design through short and focused recipes on each design aspect. The second edition of this book focused on vSphere 6.0. vSphere features released since then necessitate an updated design guide, which includes recipes for upgrading to 6.7, vCenter HA; operational improvements; cutting-edge, high-performance storage access such as RDMA and Pmem; security features such as encrypted vMotion and VM-level encryption; Proactive HA; HA Orchestrated Restart; Predictive DRS; and more. By the end of the book, you will be able to achieve enhanced compute, storage, network, and management capabilities for your virtual data center.

Using jumbo frames

Enabling jumbo frames on the networks that's used for vMotion or IP storage can increase performance and throughput. When jumbo frames are configured, iSCSI or NFS packets can be transferred over the network in a single frame; there is no fragmentation. This decreases the amount of CPU overhead that's necessary to encapsulate (and de-encapsulate) IP storage packets.

How to do it...

Refer the following steps to design and implement jumbo frames:

  1. Determine the use cases for enabling jumbo frames
  2. Configure the jumbo frames on virtual switches
  3. Configure the jumbo frames on VMkernel ports
  4. Ensure that jumbo frames are configured end to end on the physical network, that is, physical switches and array...
