Question #: 7
Topic #: 4

[All D-PWF-OE-00 Questions]

What is the primary purpose of a Protection Domain in PowerFlex?

AGrouping nodes based on geographical location

BIsolating storage resources for fault containment

CManaging metadata for storage pools

DConfiguring node maintenance schedules

Show Suggested Answer

Suggested Answer: B

The Protection Domain (PD) is the fundamental unit of fault isolation.

Isolating storage resources for fault containment (Option B): The PowerFlex mesh-mirroring algorithm works only within a Protection Domain. Data on Node A (in PD1) will only be mirrored to other nodes inside PD1. It will never be mirrored to PD2.

Why is this important? If a catastrophic software bug or a massive power surge affects one Protection Domain, the damage is contained there. The other Protection Domains continue to function normally. It allows administrators to segment the cluster (e.g., PD_Production vs. PD_Test) to ensure that issues in one environment do not bleed into another.

But B is more about reliability. We need that in PowerFlex.

I vaguely recall something about managing metadata, but I don't think that's the main purpose. Maybe it's C?
