I thought E was more about management than workload sizing.

Wait, are we really considering A? Seems off.

I think B is also important, but not as much as C and D.

I practiced a similar question, and I think splitting of workloads was mentioned as a key factor, but I’m not entirely confident.

I feel like extent of serialization might be relevant, but I don't remember it being emphasized as much as the others.

I remember something about read vs. write ratios being important for sizing, but I can't recall if it was specifically for PowerStore.

I think the random vs. sequential I/O is definitely one of the attributes we discussed, but I'm not sure about the second one.

The question is asking about I/O workload characteristics, so I'll focus on options that describe the nature of the I/O, like random vs. sequential and read vs. write. Those seem like the most important factors for sizing the PowerStore solution.

I'm a bit confused by the options here. Is "Extent of Serialization" and "Splitting of Workloads" even relevant for this question? I'll need to double-check my understanding of these concepts.

Okay, I've got this. Random vs. sequential I/O and read vs. write ratios are definitely the two key attributes to consider when sizing the PowerStore storage.

Hmm, I'm not entirely sure about this one. I'll need to think through the different I/O workload characteristics and how they relate to sizing the PowerStore solution.

This looks like a straightforward question about I/O workload characteristics. I'll focus on identifying the two most relevant attributes from the options provided.
