The deployment example in this guide uses seven PowerEdge R650 servers running ESXi as nodes in the vSAN stretched cluster. Other server hardware may be used provided it meets the requirements covered in the vSAN Planning and Deployment, VMware vSphere 7.0 Update 3 Guide.
Note: Dell Technologies recommends using Dell vSAN Ready Nodes in vSAN clusters. Dell vSAN Ready Nodes are preconfigured, tested, and certified to run VMware vSAN.
