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.

Failover scenarios of RP4VM on VxRail

This section will discuss some failover scenarios of RP4VM, including a faulty vRPA, a faulty journal, replication links disconnected, a faulty plugin server, and a faulty vCenter Server instance.

Failure scenario 1

Figure 9.12 shows local replication of RP4VM. Which status will the protected VMs trigger if vRPA-1 is faulty in the vRPA cluster?

Figure 9.12 – Local replication of RP4VM

The running VMs can still be running in the VxRail cluster, and the services of vRPA-1 will fail over to vRPA-2. The location replication can continue to execute. You can still manage all operational tasks of RP4VM within vCenter Server. The next section will discuss another failure scenario.

Failure scenario 2

Figure 9.13 shows local replication of RP4VM. Which status will the protected VMs trigger if the connection of journal volumes is disconnected?
