VxRail node connectivity
Each VxRail node connection uses two 25 GbE SFP28 interfaces to the Dell EMC Networking S5248F-ON
switches. The switches are located in the rack for ease of manageability. All switch interfaces are configured
as a VLAN trunk interface. The External Management VLAN is untagged while the remaining four are tagged
on each downstream interface.
Figure 8 shows the connections and the associated VLANs, with the S5248F-ON switches configured as a
VLT pair. As shown in Figure 8, the VxRail node iDRAC connects to the Dell EMC Networking S3048-ON,
which serves as the external management switch.
