Design Implication


Place the consolidated cluster in the same rack.

The consolidated cluster for ROBO is constrained to a physical rack.

The initial number of required hosts for the consolidated cluster (4 ESXi hosts) is low.

You provide on-ramp and off-ramp connectivity to physical networks (for example, north-south Layer 3 routing on NSX Edge virtual appliances) to both the management and tenant workloads by using this rack.

Edge resources require external connectivity to physical network devices.

The data centers must have sufficient power and cooling to operate the server equipment according to the selected vendor and products.


Use two separate power feeds for each rack.

Redundant power feeds increase availability by ensuring that failure of a power feed does not bring down all equipment in a rack. Combined with redundant network connections to a rack and in a rack, redundant power feeds prevent a failure of the equipment in an entire rack.

All equipment used must support two separate power feeds. The equipment must keep running if one power feed fails.
