HPE CloudPhysics is the designated assessment service for gathering detailed performance and configuration analytics from existing VMware environments. It utilizes a lightweight virtual appliance called the "Observer," which is deployed into the customer's vCenter. The Observer collects comprehensive usage metrics over time without being intrusive. This data is then used to accurately model and size a new HPE SimpliVity solution based on the actual workload demands of the customer's current Dell and VMware infrastructure. This process ensures a right-sized solution, avoiding over-provisioning or under-provisioning.

A. The HPE NinjaOnline SimpliVity Sizer is a tool used to calculate the required configuration based on metrics you provide; it does not have the capability to gather these metrics from a live environment.

B. The HPE InfoSight Primary Storage sizing tool is designed for sizing HPE's dedicated storage arrays (e.g., HPE Alletra, Primera), not for Hyperconverged Infrastructure (HCI) solutions like HPE SimpliVity.

D. HPE InfoSight for SimpliVity is a cloud-based management and analytics tool for monitoring the health and performance of existing HPE SimpliVity clusters, not for assessing external, third-party environments for migration.

1. HPE CloudPhysics Official Documentation: "The HPE CloudPhysics service is based on a SaaS model that uses a lightweight, virtual appliance (the Observer) that you install in your data center. The Observer streams metadata from your virtual infrastructure to the HPE CloudPhysics portal for analysis."

2. HPE SimpliVity Sizing Process: Official HPE solution briefs and guides for SimpliVity frequently reference the use of assessment tools to gather workload data before using the sizer. "HPE and our partners use assessment tools like HPE CloudPhysics to collect data on your existing environment... This data is then used as input for the HPE SimpliVity Sizer."

3. HPE Ninja-Series Sizing Tools: The purpose of the sizer is explicitly for configuration based on known inputs. "The HPE SimpliVity Sizer helps you design an HPE SimpliVity solution based on workload requirements and host resources." The tool's interface requires manual input or import of pre-collected data.
