A mixed architecture has a combination of both the HCI and Independent architectures. As shown previously in Figure 2, there would be some storage only nodes, compute only nodes, and hyperconverged nodes as part of the same PowerFlex cluster. This architecture is desirable when working with an existing compute infrastructure and adding high-performance software-defined infrastructure. This architecture can also be a starting point for a two-layer deployment design as external workloads are migrated to PowerFlex.
