Dell VxRail™ Appliance 4.7x Administration Guide

VxRail cluster expansion

Your VxRail cluster can be scaled from a minimum of three nodes up to a maximum of 32 nodes. Additional nodes may supported through the RPQ process (see below). The VxRail Manager automated installation and scale-out features make it easy to expand your cluster as your business demands grow.

With the VxRail Manager multi-node expansion feature, you can perform cluster expansion with up to six nodes in parallel, reducing the time required to achieve greater compute and storage capacity.

VxRail models hold from one to four nodes in a rackmount chassis. You may have a partially populated appliance chassis in the cluster. You can use the empty slots in the chassis for future expansion.

You can mix different VxRail models in the same cluster. You must adhere to the following guidelines when deploying a mixed cluster:

• The first four nodes in a cluster must be of the same type and configuration. (If there are only three nodes in the cluster they must all be the same type and configuration.)
• All appliances in the cluster must be running VxRail Manager version 4.0.400 or higher.
• First-generation appliances (sold under the VSPEX BLUE name) are not supported for VxRail Manager version 4.0.400 or higher.
• Appliances using 1GbE networking cannot be used in clusters with 10GbE networking.
• Hybrid nodes cannot be used in clusters with all-flash nodes.
