Sizing the IDPA is the most important activity to complete before the installation process. Sizing the appliance provides the system administrator with a holistic view of the compute, bandwidth, and storage consumption for the workloads that the customer wants to protect using the IDPA.
To facilitate the sizing process, the system administrator (SE) and Professional Service (PS) team members can use the Solution Builder tool (Dell Technologies internal access only). This tool can generate the sizing report for the IDPA based on customer inputs and workloads that would be protected using the IDPA.
