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 Cluster Expansion

In the previous chapter, you had an overview and learned about the design of VMware vSAN on the VxRail 7.x system, including Failure Tolerance Method (FTM), Failures to Tolerate (FTT), and stripe width. You understood the relationship and instead of vSAN objects and components on different vSAN storage policies—for example, RAID 1 and RAID 5. Based on the different scenarios, you now understand the benefits of the vSAN storage policy of how to offload daily operations in the virtualization environment.

Scale-up and scale-out are the core features of the VxRail 7.x system. You can add different hardware components to an existing VxRail cluster if you plan to increase the resources on the VxRail 7.x system, including memory, number of capacity storage drives, and number of VxRail nodes. Each model of VxRail supports different scale-up configurations. This chapter will discuss the design of disk groups on each type of VxRail 7.x system—that...
