What allows for array upgrades without any degradation in performance?

The feature that allows forarray upgrades without any degradation in performanceisnon-disruptive upgrades.

Why This Matters:

Non-Disruptive Upgrades:

Pure Storage FlashArray supports rolling upgrades, enabling software updates (e.g., Purity//FA) and hardware upgrades (e.g., controllers) without interrupting operations.

During a controller upgrade, the active/active architecture ensures that one controller continues handling I/O operations while the other is upgraded, maintaining consistent performance.

Why Not the Other Options?

A. ActiveCluster:

ActiveCluster provides synchronous replication for high availability but does not directly relate to non-disruptive upgrades.

C. Right-Size Guarantee:

The Right-Size Guarantee ensures customers receive the expected effective capacity based on their workload's data reduction profile. It is unrelated to upgrades or performance.

D. Protection groups:

Protection groups are used for replication and snapshot management but do not impact the ability to perform non-disruptive upgrades.

Key Points:

Non-Disruptive Upgrades:Ensure seamless updates without impacting performance or availability.

Active/Active Architecture:Enables continuous I/O processing during upgrades.

Customer Experience:Minimizes downtime and disruption during maintenance or upgrades.
