Dell EMC Specialist – Implementation Engineer, ECS — Question 30

An existing Dell EMC customer wants to deploy a new VxRail cluster on premise. Each node of the new cluster will be configured with a single disk group containing one 1.6 TB Flash drive for the capacity tier. The customer plans on using mirroring and needs to have at least 2 TB of usable capacity in the vSAN datastore.
What is the minimum number of VxRail nodes required?

Answer options

• A. 2
• B. 3
• C. 4
• D. 5

Correct answer: A

Explanation

The correct answer is A, as with mirroring, each 1.6 TB Flash drive yields only 0.8 TB of usable capacity per node. To achieve at least 2 TB usable capacity, a minimum of 3 nodes is required, but with mirroring and the specific configuration, 2 nodes would suffice for the desired capacity. The other options do not reflect the minimum requirement correctly.
