How many data storage VMs must a cluster contain to serve data to clients?

To serve data to clients, a cluster must contain at least one data storage virtual machine (VM). This single data storage VM is responsible for presenting the storage resources to client applications. It handles client requests, manages data storage, and ensures the availability of the data.

Having at least one data storage VM allows the cluster to operate and facilitate communication with clients seeking access to stored data. If there were no VMs present, the cluster would not have the capability to provide any data services. Therefore, the presence of at least one data storage VM is fundamental for effective data management and client interactions in a cloud or virtual environment.
