HPE7-J02 Exam Dumps : Advanced HPE Storage Integrator Solutions Written Exam

Detailed Explanation:

Rationale for Correct Answer:

HPE CloudPhysics provides comprehensive environment assessment and competitive sizing for virtualized environments (VMware, Hyper-V, etc.). The CloudPhysics collector (available as a .vhdx for Hyper-V) is deployed into the cluster to gather metrics on CPU, memory, storage IOPS/latency, and utilization trends. These analytics feed into the sizing of HPE storage solutions.

Distractors:

B: InfoSight sizing tools work with HPE systems, not competitive 3rd-party storage like Pure.

C: SAF is a manual assessment requiring email submission and is not the correct modern method for this case.

D: NinjaProtected applies to backup analysis, not production Hyper-V cluster sizing.

Key Concept: CloudPhysics.vhdx collector for Hyper-V sizing with 3rd-party infrastructure.

Detailed Explanation:

Rationale for Correct Answer:

In Alletra 5000/6000 sizing, the Failure Domain Reserve (FDR) is used to account for rebuild overhead in case of drive failure. HPE best practices define that, unless otherwise directed by the sizing tool or customer requirements, the minimum FDR value should be set to 23% of the largest drive size. This ensures enough reserve capacity for fault tolerance and sustained performance during rebuilds.

Distractors:

B/C: Low-read latency is influenced by cache and workload profile, not by arbitrary FDR percentages.

D: Using the smallest drive is incorrect — rebuild impact must be sized against the largest drive.

Key Concept: FDR sizing based on 23% of largest drive = HPE best practice.

Detailed Explanation:

Rationale for Correct Answer:

For competitive or 3rd-party (non-HPE) environments like Dell + VMware, HPE CloudPhysics is the correct tool. The Observer VM is deployed into vCenter to gather real-world workload metrics (CPU, memory, storage I/O). These analytics can then be used for SimpliVity HCI sizing.

Distractors:

A: NinjaOnline SimpliVity Sizer requires input metrics, but it cannot directly collect from 3rd-party environments.

B: InfoSight sizing applies to HPE arrays, not competitive storage.

D: InfoSight for SimpliVity only monitors existing HPE SimpliVity clusters.

Key Concept: CloudPhysics Observer → gathers competitive workload metrics → feeds into SimpliVity sizing.
