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.

Identifying RAID levels


Redundant Array of Independent Disks (RAID) combines multiple physical disks into a single unit of storage. The advantages in speed, reliability, and capacity can be realized depending on which RAID level is selected. RAID provides the first level of protection against data loss due to a disk failure.

How to do it...

In order to select the proper RAID level required to support virtual workloads, you need to perform the following steps:

  1. Identify the different RAID levels and capabilities.

  2. Select an appropriate RAID level to support a virtualized workload based on capacity and performance requirements.

How it works...

RAID0 stripes disks together to appear as a single disk with a capacity equal to the sum of all the disks in the set. It provides excellent performance and capacity efficiency but offers no data protection. If a disk fails in a RAID0 set, the data is lost and must be recovered from a backup or some other source. Since this level offers no redundancy, it is not...
