VMware vSphere 6.x Datacenter Design Cookbook - Second Edition

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. With the release of 6.x a whole range of new features has come along such as ESXi Security enhancements, fault tolerance, high availability enhancements, and virtual volumes, thus simplifying the secure management of resources, the availability of applications, and performance enhancements of workloads deployed in the virtualized datacenter. This book provides recipes to create a virtual datacenter design using the features of vSphere 6.x by guiding you through the process of identifying the design factors and applying them to the logical and physical design process. You’ll follow steps that walk you through the design process from beginning to end, right from the discovery process to creating the conceptual design; calculating the resource requirements of the logical storage, compute, and network design; mapping the logical requirements to a physical design; security design; and finally creating the design documentation. The recipes in this book provide guidance on making design decisions to ensure the successful creation, and ultimately the successful implementation, of a VMware vSphere 6.x virtual data center design.

Determining the storage performance requirements


Storage performance is an important factor in storage design. The storage must be designed to meet not only the capacity requirements, but also the performance requirements for writes to and reads from the 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 the number of IOPS a workload requires.

  2. Identify the percentage of read IO to write IO for the workload.

  3. Determine the write penalty of the RAID level that will host the workload.

  4. Calculate the IOPS the storage must be capable of providing in order to support...
