The following figure shows the network architecture of the VxRail and PowerFlex nodes:
At the physical layer, two Top of Rack (TOR) (Dell or Cisco) switches are used for redundancy and load-balancing purposes. On both the TOR switches, configure Virtual Link Trunking (VLT) or Virtual Port-Channel depending on the type of switch used. Create appropriate VLANs to separate different traffic types on the physical interfaces.
The following table shows the network components:
Table 2. Network components
VxRail dynamic node: mgmt/cust_dvswitch
This vDS component is for ESXi management, vMotion, VM network, application traffic, and so on.
VxRail dynamic node: flex_dvswitch
This vDS component is for PowerFlex data network: communication between SDCs and SDSs that carries PowerFlex front-end storage traffic.
PowerFlex storage-only node: bond0
This component is for PowerFlex storage management, the data network, and the replication network (optional based on requirement).
PowerFlex storage-only node: bond1
This component is for the PowerFlex data network and replication network (optional based on the requirement).
