[All Dell VxRail Operate 2023 Questions]

An environment has two VxRail Clusters with the following configuration

* Cluster-A is using FTT = 2 and FTM = Erasure Coding

* Cluster-B is using FTT = 2 and FTM = Mirroring

A 100 GB VM is planned to be vMotioned from Cluster-A to Cluster-B. How much more vSAN capacity is consumed in Cluster-B than in Cluster-A?

A100 GB

B167 GB

C150 GB

D0 GB

Show Suggested Answer

Suggested Answer: B

To calculate the additional vSAN capacity consumed when a 100 GB VM is vMotioned from Cluster-A to Cluster-B, consider the following:

Cluster-A: FTT = 2 and FTM = Erasure Coding (RAID 6), which uses approximately 1.5 times the data size, thus 100 GB VM uses about 150 GB of vSAN capacity.

Cluster-B: FTT = 2 and FTM = Mirroring (RAID 1), which uses 3 times the data size, thus 100 GB VM uses 300 GB of vSAN capacity.

The difference in vSAN capacity consumed between Cluster-B and Cluster-A is: 300 GB (Cluster-B) - 150 GB (Cluster-A) = 150 GB

So, Cluster-B consumes 150 GB more vSAN capacity than Cluster-A.

Hmm, I think the answer is B) 167 GB. If Cluster-A is using Erasure Coding, it will only consume 100 GB, but if Cluster-B is using Mirroring, it will consume 200 GB, so the difference is 167 GB.
