Dell Technologies node expansion focuses on increasing the capacity of an existing solution that is powered by a Dell Integrated System (hybrid or all-flash scale unit). 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 scale unit 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 scale unit nodes.
Node expansion for the solution is an automated process. Full details are available in the Dell Integrated System for Microsoft Azure Stack Hub Customer Node Expansion Guide.
The following figure shows the workflow of customer delivery and deployment of node expansion for the Dell Integrated System.
The following figure shows the high-level workflow for adding an SU node to an Azure Stack Hub SU.
The following table lists the minimum hardware components that are required for the node expansion process.
|Operational Dell Integrated System for Microsoft Azure Stack Hub||1|| |
Existing customers owning a Dell Integrated System server (hybrid, all-flash, or dense configuration)
For details about the servers, see:
PowerEdge R640 server for HLH and all-flash scale unit
PowerEdge R740xd server for hybrid scale unit
PowerEdge R840 server for dense and GPU scale unit
|Additional scale unit nodes||1 or 4 (multiples)|| |
You can only order scale unit 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 Integrated System to which new scale unit 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 Integrated System switch-ports configuration (ToRs and BMC) when adding new scale unit nodes as part of the Dell Technologies node expansion.
