To double the throughput on an existing dual XtremIO X1 10 TB X-Brick cluster, adding a dual 10 TB X-Brick Expansion Kit is recommended.
XtremIO uses a scale-out architecture, and adding a dual X-Brick expansion will increase both storage capacity and performance.
This expansion ensures balanced performance improvement and leverages the best practices configuration already in place for the existing setup.

Wait, why not just add more hosts instead of expanding the X-Brick?

I think a single 20 TB X-Brick Expansion Kit could work too.

Seems like a no-brainer to go for the dual 20 TB option!

A dual 20 TB X-Brick Expansion Kit would definitely double the throughput.

I feel like the dual 10 TB option could be a good choice, but I’m not entirely sure if that would actually achieve the desired performance boost.

I’m a bit confused about the capacity needed. Would a single 20 TB X-Brick really double the throughput, or is it more about the dual setups?

I think I practiced a question similar to this, and it mentioned that adding more bricks increases performance. Maybe the dual 20 TB option?

I remember something about needing to scale out for better throughput, but I'm not sure if a single or dual expansion kit is better.

I'm a little confused by the wording of the question. Does "doubling the throughput" mean we need to double the storage capacity, or is there another way to achieve that performance gain? I'll have to re-read the details carefully.

Okay, I've got this. The question states the hosts are already configured and tuned, so the best option is to add a single 20 TB X-Brick Expansion Kit. That will double the storage capacity and likely the throughput as well.

Hmm, I'm a bit unsure about this one. Increasing the storage capacity doesn't necessarily mean the throughput will double. I'll need to think through the details to figure out the right approach.

This looks like a straightforward question about expanding a storage cluster to increase throughput. I'll carefully read through the options and think about the requirements to determine the best solution.
