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.

Overview of VMware SRM

We will start by going through an overview of VMware SRM. VMware SRM is a DR and data replication solution. It supports two protection methodologies: VM replication and storage replication. Figure 8.1 shows a conceptual overview of VMware SRM. There are two sites (Protected Site and Recovery Site), and each site contains a protected workload and a non-protected workload. In a protected workload, you can define the SRM recovery plan by using vSphere Replication and storage replication, with both configurations in the recovery site. If the protected site is down, you can execute the SRM recovery plan to recover the VMs in the recovery site:

With the preceding information, you should understand how VMware SRM works. Now, we will discuss the architecture of the VMware SRM solution.
