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.

Design of vSAN 2-Node Cluster on VxRail

In the previous chapter, we learned about cluster expansion in the VxRail 7.x system, including the scale-out and scale-in rules for each model for a VxRail node. Compared to the traditional server and storage architecture, VxRail cluster expansion is very easy and flexible.

Three VxRail nodes with the same hardware configuration are required in a VxRail cluster when you build a VxRail cluster prior to VxRail v4.7.100. Starting with VxRail v4.7.100, there is support for a vSAN two-node cluster on VxRail. The VMware vSAN two-node cluster on VxRail is designed for small-scale deployments, and the workloads and High Availability (HA) requirements are low. In this chapter, you will learn about VxRail vSAN two-node clusters, and we will discuss how to plan and design a VxRail vSAN two-node cluster.

This chapter includes the following main topics:

  • Overview of VxRail vSAN two-node clusters
  • Designing a VxRail vSAN two-node cluster
  • ...
