HPE7-J02 Exam - Topic 5 Question 2 Discussion

Actual exam question for HP's HPE7-J02 exam

Question #: 2
Topic #: 5

[All HPE7-J02 Questions]

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?

ABy adding another expansion shelf

BBy increasing the amount of 10/25 Gb NICs

CBy replacing 10/25 Gb with a 32 Gb FC HBA

DBy adding SCM to the solution

Show Suggested Answer

Suggested Answer: B

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.

Adding another expansion shelf sounds familiar, but I don't think it directly impacts sequential read performance like the other options might.

I feel like replacing the 10/25 Gb NICs with a 32 Gb FC HBA could improve performance, but I wonder if that would be overkill for this setup.

I think the key here is to identify the bottleneck in the current configuration. If the network is the limiting factor, then adding more NICs or faster ones could be the way to go. But if the storage is the issue, then SCM might be the better solution.

Adding another expansion shelf could be a good way to increase the storage capacity, but I'm not sure if that would directly improve the read performance. I'll need to consider the other options as well.

I'm a bit confused by the options here. Replacing the 10/25 Gb NICs with a 32 Gb FC HBA seems like it might work, but I'm not sure if that's the most efficient approach. I'll need to think this through.

Okay, let's see. The question is asking about improving the read performance, so I'm thinking adding more network interfaces or faster storage like SCM could be the way to go.

Hmm, this looks like a tricky one. I'll need to carefully analyze the exhibit and the options to figure out the best way to enhance the sequential read performance.
