In the logical design for ESXi, you determine the high-level integration of the ESXi hosts with the other components of the VMware Cloud Foundation instance for providing virtual infrastructure to your workloads and NSX Edge nodes.

To provide the resources required to run your workloads and NSX Edge nodes on VMware Cloud Foundation, each ESXi host consists of the following elements:

  • CPU and memory

  • Storage devices

  • Out of band management interfaces

  • Network interfaces

Figure 1. ESXi Logical Design
An ESXi host has CPU and memory for compute, vSAN local storage and non-local storage, and NICs for virtual switch uplinks and a card for out of band host management.
