We used the PowerEdge MX7000 modular infrastructure to provide the network switching layer in this solution. The network layer consists of:
- Two MX9116n Fabric Switching Engine (FSE) I/O Modules (IOMs) or switches—We configured two MX9116n IOMs installed in MX fabric slot A1 and MX fabric slot B1 to run converged LAN and SAN traffic in this solution. We configured the two IOMs in Virtual Link Trunking (VLT) mode. We configured the two QSFP28 (100 Gb) external-facing unified ports in four 16 Gb/s Fibre Channel (FC) break-out mode and directly attached them to the PowerMax 2000 storage array. We configured the QSFP28 external-facing port in four 10 GbE break-out mode and uplinked it to spine switches for external LAN connectivity. We configured the 25 GbE internal-facing ports that we connected to the CNA ports in the MX840c blades to carry FCoE traffic and LAN traffic. For details about the LAN and SAN network configuration, including FC zoning, see Compute and network design in Appendix B.
- Redundant MX management module—We connected redundant 1 GbE MX management modules to 1 GbE switches. We used this management module to manage the MX7000 chassis and MX9116n IOMs, and to connect to the iDRACs on the MX840c blades.
