System scale-out upgrades
VxRail Appliance is designed to scale-up system capabilities as workloads requirements grow.
You can add NICs, memory and storage capacity to existing nodes, or add nodes to the cluster.
Adding storage and nodes to an existing cluster are customer procedures, with Dell EMC
services available if needed. Other upgrades such as adding memory and GPUs are performed
by Dell EMC Customer service.
Adding a node to an existing cluster
Node upgrades are shipped from the factory with ESXi and other VxRail software pre-installed.
Dell EMC Professional Services install the nodes in the rack, cables it to the network switches,
and connects power.
Procedure
1. Power on the new appliance.
Once the appliance is powered on, it broadcasts availability and VxRail Manager displays
the available node in the Dashboard view of VxRail Manager. The following figure shows an
example of a newly detected node ready to be added to the cluster.

2. Click Add Node to add the new nodes to the cluster.
Prior to the VxRail 4.5 release, nodes were added one at-a-time. Beginning with VxRail 4.5,
up to six new nodes can be selected and added in a single operation.
3. Enter the vCenter credentials.
The figure below is an example screenshot of this prompt. Administrator credentials or the
credentials of a user with necessary permissions to add a node to the cluster is required.
