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 disk groups on VxRail D-Series

Figure 5.22 shows the front view of VxRail D560/F. There are only eight disk slots on VxRail D560/F; disk slots 0 to 5 are used for the capacity tiers, and disk slots 6 to 7 are used for the cache tier. The capacity disks support SAS/SSD, and the cache disks support SSD:

In the release of VxRail 7.0.201 or later, VxRail D560/F only supports one option of a disk group, which contains one cache disk and up to three capacity disks per disk group. Table 5.11 shows a disk group configuration for each disk slot in VxRail D560/F:
