Hitachi Vantara HCE-3700 Exam - Topic 5 Question 44 Discussion

A VSP G1000 performance analysis shows that server response times for virtualized volumes are high, 100 ms and higher, but HDD utilization rates in an external HUS 150 never exceed 35%. There are no processor or path constraints in the configuration. The workload is steady and stable. Which two actions will optimize this configuration? (Choose two.)
A) Increase the external path LUN queue depth in the VSP G1000. and B) Spread the server load across more and smaller LUNS per RAID group in the HUS.
C) Break up each HUS LUN into several smaller volumes in the VSP G1000.
D) Migrate the HUS LUNs to RAID groups with faster HDDs. References: https://manualzz.com/doc/13486869/optimize-hitachi-storage-and-server-platforms-in-vmware-v...

Option D sounds good too, faster HDDs could really improve performance.

Not sure about option C, breaking up LUNs might complicate things.

Surprised that HDDs are underutilized but response times are still high!

I think option B is a better choice, spreading the load could help a lot.

Definitely go with option A, increasing the LUN queue depth makes sense.

Migrating to faster HDDs seems like a solid option, but I’m hesitant since the current utilization is so low. Would that really make a difference?

I practiced a similar question where breaking up LUNs improved response times. I wonder if that applies here too.

Spreading the load across smaller LUNs sounds familiar; I think it could help with performance, but I’m not entirely confident about the specifics.

I remember we discussed LUN queue depth in class, but I'm not sure if increasing it is the right move here since the HDD utilization is low.

I'd go with customer order fill rate. That's the ultimate goal of the master scheduling process, so it makes sense to use that as the key performance indicator.

Hmm, I'm a bit unsure about this one. The question mentions "faster" loading, so I'll need to carefully consider the different API options and their performance characteristics. I may need to do some research on the Bulk API versus the other choices.

I'm a little confused by this question. Are we talking about the redo log files or the archive log files? The solutions could be different depending on the specific issue. I'll need to re-read the question carefully.
