SONiC is a network operating system for switch configuration and monitoring. The starting point is a single rack setup using a single leaf-pair deployment using L2 uplinks to DNS and NTP services. The multirack setup for this deployment uses a BGP EVPN VXLAN network virtualization overlay with L3 uplinks to DNS and NTP services. The selected underlay for the routing protocol is BGP because it provides multiprotocol support for both IPv4 and IPv6.
VxRail is a hyperconverged infrastructure (HCI) solution that consolidates compute, storage, and network into a single, highly available, unified system. With careful planning, VxRail can be rapidly deployed into an existing data center environment, and the end-product is immediately available to deploy applications and services. VxRail encompasses:
ESXi node: ESXi is the virtualization platform where you create and run VMs and virtual appliances. For planning considerations and prerequisites that are not covered in this guide, see the Dell VxRail Network Planning Guide.
Note: This deployment guide provides a basic single cluster example. To add VxRail clusters, repeat these planning and configuration procedures. For information that is specific to VxRail, see the VxRail SolVe website has (account required).
