Question #: 16
Topic #: 2
[All D-XTR-DS-A-24 Questions]

A customer has a workload with the following attributes:

. Generates 500,000 IOPs

. Maximum bandwidth of 14 GB/s

Which XtremlO X2 solution should be recommended to the customer?

Show Suggested Answer Hide Answer
Suggested Answer: A

When troubleshooting SAN performance problems, a key indicator of a physical issue is a high CRC (Cyclic Redundancy Check) error count. CRC errors are indicative of corrupt data packets during transmission, which often points to issues such as faulty cables, bad ports, or other physical problems in the network infrastructure. High CRC error counts can lead to retransmissions, reduced throughput, and overall degradation of SAN performance. Addressing the physical components associated with high CRC error counts is essential for restoring optimal SAN operations.


While the specific Dell XtremIO Design document was not available, general SAN troubleshooting guidelines and best practices indicate that CRC errors are a critical metric to monitor for physical connectivity issues1.

Additional resources on SAN performance troubleshooting can be found in the support documentation for the XtremIO Family on Dell's official website2.

Wait, are we sure 2 X-Bricks won't cut it? Sounds fishy.

Not sure about 1 X-Brick, seems too low for those numbers.

I feel like 3 X-Bricks could be overkill, but I also remember that underestimating can lead to performance issues. Maybe 2 is safer?

I'm a bit confused about the maximum bandwidth. Does that mean we need to consider both IOPs and bandwidth together when choosing the solution?

I think we practiced a similar question where we had to match IOPs to the number of X-Bricks. If I recall correctly, 2 X-Bricks might be the sweet spot for this kind of performance.

I remember we discussed IOPs and bandwidth in class, but I'm not sure how to calculate the right number of X-Bricks for this workload.

No problem, I've got this. I'll methodically go through the options and identify the one that provides the optimal balance of performance and cost for the customer.

I'm a bit unsure about this one. I'll need to review the X2 solution specs carefully and make sure I understand how they relate to the given workload attributes.

Alright, time to put my problem-solving skills to the test. I'll need to evaluate each X2 solution and determine which one best meets the customer's needs.

Okay, let's see... 500,000 IOPs and 14 GB/s bandwidth. I think I need to focus on finding the solution that can handle those performance requirements.

Hmm, this looks like a classic capacity planning question. I'll need to carefully consider the workload attributes and match them to the X2 solution options.

The answer is clearly D) 2 X-Bricks. I mean, come on, it's right there in the question - the workload has 'maximum bandwidth of 14 GB/s'. Two bricks should do the trick!
