The following figure shows the logical network on a PowerFlex two-layer configuration with an MX7000 solution with four data networks:
There were two VLAN design changes on the PowerFlex Management Controller from our standard logical design, which are shown in red:
The management/production MX91B16n switches provide network connectivity to the customer environment and are connected, as shown in the following figure:
The MX9116n FSE modules that are located inside the B chassis slots provide storage connectivity to the PowerFlex storage-only nodes, as shown in the following figure:
The MX7116n FEM modules are used to connect multiple chassis. The following figure shows the MX7116n FEM module and its associated connectivity ports:
To provide a better representation of a fully cabled system, the following figure shows the MX9116n FSE and MX7116n FEM connections:
Each node in the MX740c compute architecture is inserted into an MX7000 chassis and contains two network mezzanine adapters. Each mezzanine adapter contains two 25 GbE network links for a total of four 25 GbE links per node. The following figure shows that the mezzanine adapters are hard wired to a specific fabric slot.
Note: This detail was considered when we configured the MX7000 chassis and associated nodes for maximum high availability.
Because each chassis contains a pair of MX9116n FSE modules and a pair of MX7116n FEM modules, the internal connections alternate when Chassis1 Node1 is compared with Chassis2 Node1 for high availability and redundancy purposes. Each mezzanine card is connected to one MX9116n FSE and one MX7116n FEM.
