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.

VxRail satellite nodes

In the preceding sections, we learned the difference between VxRail nodes with vSAN and VxRail dynamic nodes. From VxRail 7.0.320 or above, the VxRail satellite node is available. This node is a type of VxRail node and it supports lifecycle management through VxRail Manager. But it only requires a single IP address to connect to the VxRail cluster in an HQ data center.

In Figure 2.8, there is a VxRail cluster with four nodes in the HQ data center and one VxRail satellite node in each remote site (A, B, and C). Each VxRail satellite node and VxRail cluster is managed by a single vCenter instance through a Wide Area Network (WAN) in the HQ data center. If you deployed these nodes in your environment, the virtual machines could be running on local RAID storage (PERPC H755 controller) or secondary storage.
