Design of vSAN 2-Node Cluster on VxRail

In the previous chapter, we learned about cluster expansion in the VxRail 7.x system, including the scale-out and scale-in rules for each model for a VxRail node. Compared to the traditional server and storage architecture, VxRail cluster expansion is very easy and flexible.

Three VxRail nodes with the same hardware configuration are required in a VxRail cluster when you build a VxRail cluster prior to VxRail v4.7.100. Starting with VxRail v4.7.100, there is support for a vSAN two-node cluster on VxRail. The VMware vSAN two-node cluster on VxRail is designed for small-scale deployments, and the workloads and High Availability (HA) requirements are low. In this chapter, you will learn about VxRail vSAN two-node clusters, and we will discuss how to plan and design a VxRail vSAN two-node cluster.

This chapter includes the following main topics:

• Overview of VxRail vSAN two-node clusters
• Designing a VxRail vSAN two-node cluster
