Discuss NetApp NS0-593 Exam Topic 2 Question 74

You have a customer who is concerned with high CPU and disk utilization on their SnapMirror destination system. They are worried about high CPU and disk usage without any user operations.

In this situation, what should you tell the customer?

ASuggest that the customer manually cancel any scanners on the destination to reduce CPU usage.

BExplain that background tasks such as SnapMirror throttle up in the absence of user workload.

CSuggest that the customer throttle their SnapMirror relationships to reduce resource consumption.

DExplain that only user workload should use the CPU and Investigate further.

Suggested Answer: B

SnapMirror is a data replication technology that allows efficient and flexible data protection and disaster recovery for NetApp ONTAP storage systems1

SnapMirror transfers data between source and destination volumes using a network connection.SnapMirror can use storage efficiency features such as compression and deduplication to reduce the amount of data transferred and stored1

SnapMirror transfers are scheduled and controlled by policies that define the frequency, retention, and priority of the transfers.SnapMirror policies can also specify the network bandwidth limit for the transfers2

SnapMirror transfers are considered background tasks that run in the absence of user workload.SnapMirror transfers can consume CPU and disk resources on both source and destination systems, depending on the amount and type of data being replicated3

SnapMirror transfers can throttle up or down depending on the availability of system resources and network bandwidth. SnapMirror transfers will throttle up when there is no user workload, and throttle down when there is user workload.This is to ensure that SnapMirror transfers do not impact the performance of user operations3

Therefore, if a customer is concerned with high CPU and disk utilization on their SnapMirror destination system, the best answer is to explain that background tasks such as SnapMirror throttle up in the absence of user workload.This is normal and expected behavior, and it does not indicate a problem with the system3

Wait, are you saying background tasks can use that much CPU? Sounds odd.

I agree, throttling SnapMirror might help with resource issues.

Derick 10 months ago

Background tasks can definitely ramp up when there's no user load.

Wenona 10 months ago

Canceling scanners could help, but it might not be the best long-term fix.

I think user workload should be the main concern, not just background tasks.

Juliana 11 months ago

I’m a bit confused about whether user workload is the only thing that should use CPU. Option D seems a bit off, but I’m not completely sure.

Lamar 11 months ago

I practiced a similar question where we discussed CPU usage, and I think we concluded that background tasks can cause high utilization. So, B sounds familiar.

Annice 11 months ago

I'm not entirely sure, but I feel like throttling SnapMirror could help with resource issues. Option C might be worth considering.

Bernardine 11 months ago

I think I remember something about background tasks using resources when there's no user activity. Maybe option B is the right choice?

Alishia 12 months ago

I think the best approach here is to suggest throttling the SnapMirror relationships to reduce resource consumption. That seems like the most straightforward solution.

Andrew 12 months ago

I'm a bit unsure about this one. I'll need to review the options carefully and make sure I understand the implications of each before deciding.

Graciela 12 months ago

I'm pretty confident this is due to SnapMirror throttling up in the absence of user workload. I'd suggest explaining that to the customer.

Okay, let's see. The high CPU and disk usage without any user operations sounds like it could be related to background tasks like SnapMirror. I'll need to look into that more.

Keshia 1 year ago

Hmm, this is a tricky one. I'll need to think carefully about the potential causes and solutions here.

CPU and disk usage without any user operations? Sounds like the SnapMirror is trying to take over the world!

Or just explain the background tasks to the customer.

Maybe suggest throttling the SnapMirror? Could help!

Yeah, I think SnapMirror just ramps up when it's quiet.

Sounds like a classic case of background tasks running wild!

Option B seems like the way to go. Background tasks gotta do their thing, you know?
