An administrator is tasked to optimize storage utilization in an existing VMware vSAN Original Storage Architecture (OSA) cluster.
The cluster has the following configuration:
Eight-node cluster with 1 disk group per node.
Virtual machines (VMs) are configured with 1 failure - RAID-1 storage policy.
Storage utilization is at 70%.
Which action can the administrator take to reduce the existing storage utilization with the minimum impact to the cluster?

Changing to 2 failure - RAID-6 is risky. Better stick with A for safety.

C could work too, but only Compression might not save enough space.

I agree, A seems effective. Minimal impact on performance too.

I think A is the best choice. Deduplication and Compression can save a lot of space.

Totally agree with A, it's the best option for reducing space!

Wait, changing to 3 failure - RAID-1? That sounds risky!

I think C) Enable Compression only is a safer choice.

If I remember correctly, RAID-6 would require more space due to the additional parity, so that option seems counterproductive for reducing utilization.

I practiced a similar question where enabling compression alone was the best option, but I can't recall if it was the same scenario with deduplication.

I'm not entirely sure, but I think changing the storage policy to 3 failure - RAID-1 might actually increase utilization instead of reducing it.

I remember we discussed how enabling deduplication and compression can significantly help with storage efficiency in vSAN.

Compression is the way to go! Option C is the clear winner. Who needs deduplication when you've got compression?

Hmm, I'm not sure about Option B. Increasing the failure tolerance might not be necessary here.

Option D looks interesting, but changing the storage policy to RAID-6 might be overkill for this scenario.
CO

I'd go with Option C. Compression alone should be enough to reduce the utilization without impacting the cluster.
LI

Option A seems like the way to go. Deduplication and compression can really optimize storage usage.

I'm feeling pretty confident about this one. I think option A is the way to go to optimize storage utilization.

Deduplication and compression seem like a good place to start, but I want to make sure I understand the other options too.
GL

A) Enable Deduplication and Compression is the way to go!
FL

Okay, I think I've got a strategy here. I'll focus on the minimum impact requirement and go from there.

Hmm, I'm a bit confused by the storage policy details. I'll need to review those before deciding.

Not sure if Deduplication will really make a big difference...
