Show Suggested Answer

Suggested Answer: B

The minimum supported network throughput in Gb/s for each host in an all flash vSAN cluster based on the vSAN Original Storage Architecture (OSA) is 10.

vSAN Express Storage Architecture (ESA) are only supported with 25Gbps and higher connection speeds. ESA ReadyNodes configured for vSAN ESA will be configured with 25/50/100Gbps NICs. vSAN OSA all-flash configurations are only supported with a 10Gb or higher connections. One reason for this is that the improved performance with an all-flash configuration may consume more network bandwidth between the hosts to gain higher throughput. https://core.vmware.com/resource/vmware-vsan-design-guide#sec6815-sub3

1 Gb/s? Really? That's way too low for a modern all-flash vSAN setup.

I thought it was 10 Gb/s. Guess I need to brush up on my vSAN knowledge.

The correct answer is C) 25 Gb/s. That's the minimum required for a vSAN OSA cluster.

I thought it was 10 Gb/s too, but I could be confusing it with the requirements for a different setup.

I’m leaning towards 50 Gb/s, but I might be mixing it up with another technology.

I remember practicing a question about vSAN throughput, and I feel like 25 Gb/s was mentioned as a common requirement for performance.

I think the minimum supported throughput for vSAN OSA is 10 Gb/s, but I'm not entirely sure.

I'm pretty confident the answer is 25 Gb/s. The question specifies the "vSAN Original Storage Architecture", and that's the key detail that points to the 25 Gb/s requirement.

Wait, is it really 25 Gb/s? I thought the minimum for vSAN was only 10 Gb/s. I'm going to have to double-check that before answering.

Okay, I've got this. The minimum network throughput for a vSAN OSA cluster is 25 Gb/s per host. That's option C.

Hmm, I'm not too familiar with the vSAN OSA, so I'm a bit unsure about this one. I'll need to review my notes on the different vSAN architectures.

I think the key here is to focus on the "vSAN Original Storage Architecture" part of the question. That should give us a clue about the minimum network throughput required.
