Pure Storage Exam FBAP_002 Topic 3 Question 46 Discussion

Actual exam question for Pure Storage's FBAP_002 exam

Question #: 46
Topic #: 3

A customer reports far lower than expected performance on the FlashBlade, in a Oracle RMAN backup solution. The environment consists of four Oracle database nodes, each with 1x10Gb/s NIC, connected via NFS, to a fully populated FlashBlade chassis. Only a small number of blades are being used. Synthetic performance testing shows no performance issues in the network.

What should the architect suggest to causing this issue?

AOracle RMAN uses HCC compression, so this a poor use case for FlashBlade.

BdNFS is not enabled on the Oracle nodes or the number of RMAN channels is too low. ***

CThe sustained write performance of a 15 blade FlashBlade is 1.5GB/s

DThe FlashBlade only has 8x10Gb/s uplink connectivity to the customer's top of rack switches.

Ooh, a poor use case for FlashBlade? Sounds like someone's trying to sell us some snake oil. I'll stick with the dNFS option, thank you very much.

No way, the sustained write performance of the FlashBlade should be enough for this setup.

I think the HCC compression might be the real culprit here.

But what about the low number of RMAN channels? Could that be causing the problem?

I agree, dNFS not being enabled could definitely be the issue.

8x10Gb/s uplinks? That's like having a sports car with a bicycle chain. No wonder they're seeing performance issues!

1.5GB/s? That's a pretty decent sustained write performance for a 15 blade FlashBlade. I don't think that's the problem.

Yeah, that could definitely be causing the performance problem. They should check that out.

Maybe the architect should suggest enabling dNFS and increasing the number of RMAN channels to improve performance.

Wait, Oracle RMAN uses HCC compression? That's news to me. I don't think that would be the cause of the performance issues here.

I agree with you, Tayna. It could also be that the number of RMAN channels is too low.

The issue is definitely with the dNFS configuration or the number of RMAN channels. If those aren't set up properly, you're not going to get the performance you expect from the FlashBlade.

I think the issue might be related to dNFS not being enabled on the Oracle nodes.
