What is skew?

Show Suggested Answer Hide Answer
Suggested Answer: D

Skew refers to the non-uniform distribution of I/O over storage capacity. In storage systems, skew is an important factor to consider as it indicates that certain areas of the storage receive more I/O operations than others. This can lead to performance hotspots and affect the overall efficiency of the storage system. Managing skew is essential to ensure balanced performance across the storage array.

I'm a bit confused; I thought skew was more about sustained performance, but that might be related to B instead.

I practiced a question like this, and I feel like skew has to do with uneven distribution, which makes me lean towards D.

I remember something about bursty IOPS, but I'm not sure if that relates to skew. Could it be C?

I think skew refers to how I/O isn't evenly spread out, so maybe it's D?

I'm confident that skew is related to the distribution of I/O, so I'll choose option D. It seems like the most logical answer based on what I know.
