Dell VxRail Network Planning Guide
Confirm your data center network
After configuring the switch, there should be unobstructed network paths between the switch ports and the ports on the VxRail nodes. The VxRail management network and VM network should have unobstructed passage to your data center network.
Prerequisites
Before forming the VxRail cluster, the VxRail initialization process verifies the following:
- Switch and data center environment support.
- Passage of VxRail logical networks.
- Accessibility of required data center applications.
- Compatibility with the planned VxRail implementation.
Certain data center environment and network configuration errors cause the validation to fail, and the VxRail cluster is not formed. When validation fails, the data center settings and switch configurations must undergo troubleshooting to resolve the problems.
About this task
Use the switch vendor instructions for guidance.
Steps
- External management traffic is untagged on the native VLAN by default. If a tagged VLAN is used instead, customize the switches with the new VLAN.
- Internal device discovery network traffic uses the default VLAN of 3939. If this has changed, customize all VMware ESXi hosts with the new VLAN, or device discovery fails.
- Confirm that the switch ports that attach to the VxRail nodes allow passage of all VxRail network VLANs.
- Confirm that the switch uplinks allow passage of external VxRail networks.
- If you have two or more switches, confirm that an inter-switch link is configured between them to support passage of the VxRail network VLANs.
