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.

Determining storage performance requirements

Storage performance is an important factor of storage design. The storage must be designed to meet not only the capacity requirements but also the performance requirements for writes and reads to disk. Disk performance is measured in Input/Output per Second (IOPS). One disk read request or one disk write request is equal to one IO. The storage performance must support the current requirements and growth.

How to do it...

The IOPS required to support an application is calculated based on the percentage of read IO, the percentage of write IO, and the write penalty of the RAID level the workload will be hosted on.

To calculate the IOPS requirements, perform the following steps:

  1. Determine...
