HPE7-J02 Exam - Topic 8 Question 18 Discussion
Topic #: 8
The storage solution based on the exhibit is deployed at a customer site.
How can the sequential read performance values be enhanced for this configuration?
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.
