Step 1. Assess your requirements and perform a sizing exercise to determine the quantity and characteristics of the VxRail nodes you need to meet planned workload and targeted use cases.
Step 2. Determine the number of physical racks needed to support the quantity and footprint of VxRail nodes required to meet workload requirements, including the top-of-rack switches. Verify that the data center has sufficient floor space, power, and cooling.
Step 3. Determine the optimal VxRail port speed to meet planned workload requirements, and to calculate the number of physical switch ports for connectivity.
Step 4. Decide whether you want to attach the VxRail nodes to the switches with RJ45 connections or SFP+ connections.
Step 5. Determine the number of additional ports and port speed on the switches for the uplinks to your core network infrastructure to meet VxRail workload requirements. Select a switch or switches that provide sufficient port capacity and characteristics.
Step 6. Reserve one additional port on the switch for a workstation/laptop to access the VxRail management interface for the cluster.
Step 7. Select a switch or switches that support the features and functionality that is required for VxRail.
Step 8. Determine whether a single switch will meet business ojectives, as it is a potential single point of failure. Dual top-of-rack (ToR) switches provide protection from a switch failure.
Step 9. Decide whether to deploy a separate switch to support connectivity to the VxRail management port on each node.
