The following figure provides a high-level overview of the topology that is used for two-layer architecture. The MX7000 compute nodes used the two-layer architecture to connect to the existing PowerFlex storage-only nodes. The same VLANs and subnets used for the storage network were extended across the entire two-layer network allowing unrouted communication between PowerFlex and MX7000.
