Note: Skip this section if you do not plan to enable Dell SmartFabric Services to pass control of switch configuration to VxRail.
The planning and preparation tasks for deploying and operating a VxRail cluster on a SmartFabric Services-enabled network infrastructure differ from connecting a VxRail cluster to a standard data center network. The basic settings that are required for the initial buildout of the network infrastructure with SmartFabric Services are outlined in this section.
Enabling the SmartFabric personality on a SmartFabric Services-qualified Dell Ethernet switch initiates a discovery process for other connected switches with the same SmartFabric personality. This process forms a unified switch fabric. A switch fabric can start as small as two leaf switches in a single rack. It can expand automatically by enabling the SmartFabric personality on connected spine switches, and connected leaf switches in expansion racks.
Both the Dell Ethernet switches and VxRail nodes advertise themselves at the time of power-on on this same internal discovery network. The SmartFabric-enabled network also configures an “untagged” virtual network on the switch fabric. That virtual network enables client onboarding through a jump port for access to VxRail Manager to implement the cluster. During VxRail initial configuration through VxRail Manager, the required VxRail networks are automatically configured on the switch fabric.
Network connectivity to out-of-band management for each switch that is enabled with the SmartFabric personality is a requirement for VxRail. A reserved IP address is required for each switch.
A separate Ethernet switch outside of SmartFabric is required to support connectivity to switch management through the out-of-band network.
A reserved IP address for iDRAC connectivity to each VxRail node on this same separate management switch is recommended.
The Dell Open Management Network Interface (OMNI) plug-in must be deployed on the vCenter instance to support automated switch management after the VxRail cluster is built. The Dell OMNI vCenter plug-in is required for each Dell switch fabric pair and requires network properties to be set during the deployment process.
