Dell Technologies node expansion focuses on increasing the capacity of an existing solution that is powered by a Dell EMC Integrated System (hybrid or all-flash SU). Node expansion offers flexibility to existing customers to increase their capacity in homogenous increments of either a single node, multiple single nodes, a set of four nodes, or multiple sets of four nodes. Each new SU node must be homogenous with the nodes present in the existing stack, which means that it has the same CPU type, memory, disk number, and disk size. Customers can expand their capacity up to 16 SU nodes.
Node expansion for the solution is a semi-automated process. Full details are available to Dell Technologies employees and support-related partners in the Dell EMC Integrated System for Microsoft Azure Stack Hub Deployment Guide.
The following figure shows the workflow of customer delivery and deployment of node expansion for the Dell EMC Integrated System.
Figure 40. Customer delivery and deployment workflow for node expansion
The following figure shows the high-level workflow for adding an SU node to an Azure Stack Hub SU. The node expansion workflow is run from the OpenManage Enterprise virtual machine.

The following table lists the minimum hardware components that are required for the node expansion process.

Additional SU nodes
1 or 4 (multiples)
You can only order SU nodes in quantities of one or four. All nodes in the integrated system must be homogenous, including the nodes that are being added.
The total nodes (after the expansion is complete) cannot exceed sixteen.
Node expansion requires a working Dell EMC Integrated System to which new SU node or nodes are added. After they order new nodes, customers must ensure that the following prerequisites are met before installation:
The Dell Technologies Support team can help customers with any queries.
Customers must modify their existing Dell EMC Integrated System switch-ports configuration (ToRs and BMC) when adding new SU nodes as part of the Dell EMC node expansion.
