VxRail 2-Node Implementation Considerations (VxRail 7.0.100)

Starting with version 4.7.100, VxRail supports vSAN 2-Node for small and Remote-Office Branch-Office (ROBO) deployments. This solution works best for environments that needs hyperconverged compute and storage with a minimal configuration. VxRail 2-Node consists of two VxRail E560 nodes and a vSAN Witness Appliance. It is recommended to deploy the Witness appliance in another site but in case of lacking another site it can be deployed in the same site as vSAN 2-Node.

There are some considerations and requirements that you need to have t in place before starting the VxRAIL 2-Node implementation.

  • Supports vSAN 2-node deployments with network switches.
  • Allows the order in which sites are upgraded to be specified for stretched clusters.
  • Improves the handling of VxRail alarms in vCenter.
  • Adds a Chat with Supportbutton on the Support tab.
  • Disables node removal for vSAN 2-node clusters.

You can directly upgrade you VxRail cluster if you are running VxRail software 4.0.510 or later release. You may not upgrade VxRail appliance in the following circumstances without opening a service request;

  • If you are running a 3-node cluster running VxRail 4.5.152 or earlier
  • If you are running a stretched cluster and running VxRail 4.7.212 or earlier
  • If your cluster is in unhealthy state or has critical errors
