HPE CloudPhysics is the designated HPE tool for data-driven assessment and analytics of heterogeneous IT infrastructures. It utilizes a lightweight, agentless virtual appliance called a collector to gather metrics from the customer's environment. For a Microsoft Hyper-V cluster, the collector is deployed as a virtual machine using a .vhdx (Virtual Hard Disk v2) file. This allows CloudPhysics to analyze the existing workload (on Lenovo servers and Pure Storage) and provide accurate sizing recommendations for a new HPE Block storage solution without disrupting operations.

B: HPE InfoSight is an AIOps platform that primarily analyzes telemetry data from existing HPE infrastructure (e.g., Alletra, Nimble, ProLiant) and is not designed to collect initial performance data from third-party storage like Pure Storage for competitive sizing.

C: The SAF (Storage Assessment Foundry) suite, including SAFcollector and SAFanalyze, is a legacy HPE toolset that has been largely superseded by the more modern and comprehensive HPE CloudPhysics platform for infrastructure assessment and sizing.

D: NinjaProtected is an HPE partner tool specifically focused on sizing data protection and disaster recovery solutions (like HPE Zerto or StoreOnce), not for analyzing performance metrics to size primary block storage.

HPE CloudPhysics Official Documentation: "The HPE CloudPhysics service uses a collector virtual appliance to collect configuration, performance, and log data from your virtualized and physical infrastructure... For Microsoft Hyper-V, you can download the collector virtual appliance as a VHDX file."

2. HPE CloudPhysics Solution Brief: "HPE CloudPhysics is a SaaS-based data-driven insights and analytics platform that enables data-driven decision-making for IT... It supports heterogeneous environments including VMware vSphere, Microsoft Hyper-V, AWS, Azure, and physical servers." This confirms its use in multi-vendor environments as described in the question.

3. HPE Partner Portal Documentation on Sizing Tools: Internal and partner-facing documentation consistently positions HPE CloudPhysics as the primary tool for assessments of competitive environments. Legacy tools like SAF are no longer promoted for new assessments, and tools like NinjaProtected are explicitly categorized for data protection sizing.
