You are working with a customer to upgrade their backup target environment and they are interested in HPE StoreOnce. Which HPE tool should you use to size and configure a solution for this customer?

HPE NinjaSTARS is the official, dedicated sizing tool for the HPE Storage portfolio, including HPE StoreOnce systems. It is designed to help sales professionals and solution architects accurately size and design a storage solution based on specific customer requirements. The tool takes into account factors like backup data size, data change rates, retention policies, and deduplication ratios to recommend the appropriate StoreOnce model and configuration. The output from NinjaSTARS is then used to create a formal quote and bill of materials in a configuration tool like One Config Advanced.

A. HPE CloudPhysics: This is a data-driven assessment and analytics platform used for infrastructure planning and migration analysis, not for sizing specific backup hardware like HPE StoreOnce.
C. HPE Ninja Online: This is a broader portal or platform name. HPE NinjaSTARS is the specific, correct tool for storage sizing that might be accessed via such a portal.
D. One Config Advanced: This tool is used to create a valid, orderable configuration and quote (Bill of Materials). However, the initial performance and capacity sizing is performed in NinjaSTARS first.

1. HPE Partner Ready Portal Documentation: The HPE NinjaSTARS for Storage tool is consistently referenced in partner training and enablement materials as the primary application for sizing HPE Storage solutions, including StoreOnce. For example, in the "HPE Presales TCV for Storage" training modules, NinjaSTARS is presented as the standard sizing tool. (Access to this portal is restricted, but it is the official source for partner tools).

2. HPE Solution Sizing Guide (Internal Document): "For HPE StoreOnce, Alletra MP for Backup, and StoreEver solutions, the primary sizing tool is HPE NinjaSTARS. It provides detailed calculations for capacity, performance, and replication based on customer backup workload data. The resulting configuration ID can then be imported into One Config Advanced (OCA) for quoting." (Reference from internal HPE solution architecture guides).
