HP Exam HPE7-J02 Topic 5 Question 2 Discussion

Detailed Explanatio n:

Rationale for Correct Answe r:

The exhibit shows a system delivering ~2.3 GB/s sequential read. For large-block sequential workloads, aggregate host link bandwidth (number speed of front-end ports) is the primary limiter. Increasing the count of 10/25 Gb iSCSI NICs adds parallel lanes, raising sustained read GB/s to the hosts. This is a recommended first step in HPE sizing before changing protocols.

Analysis of Incorrect Options (Distractors):

A: Adding an expansion shelf increases capacity, not front-end bandwidth.

C: Moving to 32 Gb FC can help, but simply adding more existing 10/25 Gb ports achieves the same goal without a protocol/adapter change and is the straightforward, supported scale-out path.

D: SCM (Storage Class Memory) targets latency/IOPS; it doesn't materially lift sequential GB/s if the link budget is the bottleneck.

Key Concept: Scale front-end connectivity to increase sequential throughput; capacity or media class changes won't fix a link-limited system.
