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.

Internal vCenter Server with an external DNS

This section will discuss VxRail deployment with the internal vCenter Server and an external DNS, and go through a scenario for this VxRail deployment.

Overview

In Figure 3.1, you can see two clusters connected to an external DNS server, VxRail Cluster and vSphere Cluster, in the VMware environment. The vSphere cluster is a standard cluster that is managed with vCenter Server, and this VxRail configuration is the VxRail standard deployment option. VxRail Manager and the internal vCenter Server (embedded vCenter Server) are installed on VxRail Cluster. Each VxRail node and all virtual machines (VxRail Manager, vCenter Server, and the other virtual machines) are configured in the customer DNS server host records. All the virtual network port groups are configured on VDS in the VxRail cluster.

If you choose the VxRail deployment with the internal vCenter Server and an external DNS, you need to consider the following:

  • The internal...
