According to the HPE SimpliVity documents and learning resources, mixing nodes with different drive configurations within a cluster is not recommended, as it can result in unbalanced 10 performance and capacity utilization. This is because the HPE SimpliVity nodes use a distributed file system that replicates data across all nodes in the cluster, and the data efficiency and backup features depend on the consistent performance of the underlying storage devices. Therefore, it is best to use nodes with the same drive configuration and capacity within a cluster, and avoid mixing All-flash and hybrid nodes, or nodes with different drive types, sizes, or speeds. The other options are incorrect because they are either false or irrelevant. Mixing nodes with different drive configuration does not require an additional license, nor is it available only for AMD-based nodes. Mixing All-flash and hybrid nodes in the same cluster is not supported, as it can causeperformance and capacity issues.
