What happens to active workloads during a PowerFlex upgrade?

Question

Options

• AThey are suspended until the upgrade is complete
• BThey are migrated to another cluster
• CThey continue running without disruption
• DThey are backed up and restored post-upgrade

• A
  6% (1)
• C
  94% (16)

Explanation

PowerFlex is designed for non-disruptive upgrades (NDU), meaning active workloads keep running uninterrupted throughout the upgrade process - making option C correct. This is a core architectural feature of PowerFlex's software-defined storage, where the upgrade is performed in a rolling fashion across nodes so I/O operations never need to stop.

Why the distractors are wrong:

• A (suspended) - Suspension would mean downtime, which defeats the purpose of an enterprise-grade, always-on storage platform.
• B (migrated to another cluster) - Cross-cluster migration is not part of the NDU process; PowerFlex handles upgrades within the same cluster seamlessly.
• D (backed up and restored) - This implies destructive downtime; PowerFlex upgrades require no backup-restore cycle because data is never at risk during the process.

Memory tip: Think of PowerFlex NDU like replacing tires on a moving car - the system keeps rolling while components are swapped out one at a time. If you see "PowerFlex upgrade" on an exam, the answer almost always points to zero downtime.
