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 G-Series

This last section will discuss the disk group design for VxRail G-Series. Figure 5.25 shows the front view and rear view of VxRail G560/F. There are 24 disk slots on the VxRail G-Series chassis; disk slots 1 to 5, 7 to 11, 13 to 17, and 19 to 23 are used for the capacity tiers, and disk slots 0, 6, 12, and 18 are used for the cache tier. It supports the installation of four nodes into each VxRail G-Series chassis. VxRail G-Series supports hybrid and All-Flash configurations. The capacity disks only support 3.5” SAS/SATA, and the cache disks only support 2.5” SSD or NVMe:

In the release of VxRail 7.0.201 or later, VxRail G560/F only supports one disk group.

Each disk group contains one cache disk and up to five capacity disks per disk group. Table 5.12 shows a disk group configuration for each disk slot in the VxRail G-Series chassis:
