What is the minimum number of nodes required for creating a Fault Set in PowerFlex?

Show Suggested Answer Hide Answer
Suggested Answer: D

6 Nodes: To utilize the Fault Set feature (which provides higher availability than standard SDS grouping, typically for rack awareness), PowerFlex requires a minimum configuration.

The Math:

A Protection Domain requires a minimum of 3 Fault Sets to support the 2-copy mirroring (Primary, Secondary, and a third location for rebuilding if a set fails).

Dell PowerFlex engineering requirements state that each Fault Set must contain at least 2 SDS nodes to ensure local redundancy and performance balance within the set.

$3 text{ Fault Sets} times 2 text{ Nodes} = 6 text{ Nodes}$ minimum.

I remember it being 6 for some setups, but 3 is standard.

Wait, are you sure it's not 2? That seems low.

I recall reading that 6 nodes are required for optimal redundancy, but I don’t think that’s the minimum for a Fault Set.

I’m pretty confident it’s 2 nodes, but I could be mixing it up with another concept from the study material.

I practiced a similar question, and I feel like the answer might be 4 nodes. It just seems like a safer number.

I think I remember something about needing at least 3 nodes for a Fault Set, but I'm not entirely sure.
