Implementing VxRail HCI Solutions

Overview of this book

Hyper-converged infrastructure (HCI) can help you simplify the provisioning and daily operations of computing and storage. With this book, you'll understand how HCI can offload the day 0 deployment and day-to-day operations of a system administrator. You'll explore the VxRail Appliance, which is an HCI solution that provides lifecycle management, automation, and operational simplicity. Starting with an overview of the VxRail Appliance system architecture and components, you'll understand the benefits of the VxRail system and compare it with the environment of traditional servers and storage. As you advance, the book covers topics such as disaster recovery and active-active and active-passive solutions for VxRail. By the end of this book, you'll have gained the confidence to manage the deployment, administration, planning, and design of a VxRail system.

VxRail scale-out rules

When we seek to expand a VxRail cluster, we must stick to the following scale-out rules:

  • The first three VxRail nodes in a cluster must be of identical models.
  • Hybrid and all-flash modes, as well as an all-NVMe node, cannot mix in a VxRail cluster.
  • All VxRail nodes in a cluster must run the same network speed, such as 25 GbE, 10 GbE, or 1 GbE.
  • All VxRail nodes in a cluster must run software of the same version.
  • All G Series VxRail nodes in a chassis must be of identical models.
  • A 1 GbE network only supports the VxRail Hybrid system with a single CPU processor.
  • The expansion node must have been physically added to the VxRail cluster, and the node connected to the VxRail network.
  • The expansion node must be discovered with VxRail Manager. The external management network of a new node must be untagged on the native VLAN by default. The internal discovery network of a new node uses the default VLAN of 3939.
  • A VMware vSphere...
