HPE CloudPhysics is a SaaS-based platform designed to collect and analyze data from an existing IT infrastructure, such as a VMware vSphere cluster. It deploys a lightweight virtual appliance (Observer) to gather detailed performance, capacity, and configuration metrics over time. This data-driven insight is then used to accurately model workload requirements and provide precise sizing recommendations for a technology refresh to solutions like HPE SimpliVity. This ensures the new hyperconverged environment is right-sized based on actual, observed usage rather than estimates, preventing over-provisioning or under-provisioning.

B. HPE Storage Sizing Tool: This is a general-purpose tool for sizing traditional HPE storage arrays (e.g., Alletra, Primera) and is not the primary data collection tool for an HCI solution like SimpliVity.

C. HPE NinjaSTARS: This is an internal HPE and partner tool used for configuring, quoting, and validating solutions. It uses the output from a sizing tool like CloudPhysics but does not collect the initial data itself.

D. HPE dHCI Sizer: This tool is specifically designed for sizing HPE's disaggregated HCI (dHCI) solutions, which have a different architecture from HPE SimpliVity.

"How it works" section: The page describes the process: "The HPE CloudPhysics Observer is a virtual appliance that is deployed in the customer’s data center. It streams metadata to the HPE CloudPhysics portal for analysis... to deliver data-driven insights for smarter IT decisions." This confirms its role as the data collection and analysis tool for infrastructure assessment.
