Dell VxRail System Design and Best Practices

By: Victor Wu

Overview of this book

Virtualized systems are well established now, and their disparate components can be found bundled together in hyper-converged infrastructures, such as VxRail from Dell EMC. Dell VxRail System Design and Best Practices will take you, as a system architect or administrator, through the process of designing and protecting VxRail systems. While this book assumes a certain level of knowledge of VMware, vSphere 7.x, and vCenter Server, you’ll get a thorough overview of VxRail's components, features, and architecture, as well as a breakdown of the benefits of this hyper-converged system. This guide will give you an in-depth understanding of VxRail, as well as plenty of practical examples and self-assessment questions along the way to help you plan and design every core component of a VxRail system – from vSAN storage policies to cluster expansion. It's no good having a great system if you lose everything when it breaks, so you'll spend some time examining advanced recovery options, such as VMware Site Recovery Manager and Veeam Backup and Replication. By the end of this book, you will have got to grips with Dell’s hyper-converged VxRail offering, taking your virtualization proficiency to the next level.

Recovery scenarios of VxRail with VBR

This last section will discuss some data recovery scenarios of VxRail with VBR, including VM recovery, faulty vCenter Server, faulty backup repository VM replication, and instant recovery.

Scenario 1

Figure 10.17 shows a sample architecture of VxRail with VBR in a single site. VBR protects the VM, and the backup images of this VM are stored in the backup repository. If the VM is corrupted in the VxRail cluster, how do we recover the data of this VM? You can restore the VM backup images based on its RPO settings from the backup repository with VBR:

The next section will discuss another failure scenario, shown in Figure 10.18.

Scenario 2

Figure 10.18 shows a sample architecture of VxRail with VBR in a single site. What is the impact on VBR if the embedded vCenter Server instance is unavailable in the VxRail cluster? All backup jobs will...
