Dell VxRail Network Planning Guide

Routing services

VxRail cluster operations depend on the networks that run on both the virtual network inside the cluster and on the adjoining physical network switches.

Some of the networks for VxRail management and for end-user access must be passed to the upstream network. Other VxRail networks can stay isolated on the adjoining network switches.

You should reserve VLAN IDs in your data center network to be assigned to support the VxRail networks, especially for production workloads. All reserved VLANs must be configured on the adjoining physical switches that are connected to the VxRail nodes. The VLANs cannot be configured as private VLANs.

Certain VxRail management components must be able to connect to data center services, such as DNS and NTP. Routing services must be configured to enable connectivity to these services for these management components. Other networks, such as those required for end-user access must also be configured to support routing end-users and external applications to the VMs running on the VxRail cluster.

If L3 routing services are not configured on the adjacent physical switches, the VLANs that need to pass upstream must be configured on adjoining network switch uplinks. Services must also be configured on the ports on the upstream network devices, so they can pass through upstream to L2 or L3 networks. If L3 services are enabled on the adjacent physical switches, configure the VLANs that need to pass upstream to terminate at this layer. Configure routing services for these networks to pass upstream.
